This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]15false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]26false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and leveraged derivative instruments, which primarily consist of equity index swap agreements, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Funds benchmark. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The S&P 500® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poors Corporation (S&P) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $2 billion to $401.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 8.22%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 7.01%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.  Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]58false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 137% of the average value of its portfolio. The Funds portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Funds portfolio turnover rate might be significantly higher.falsefalsefalsenonnum:textBlockItemTypenaDisclose the portfolio turnover rate provided in response to Item 14(a) for the most recent fiscal year (or for such shorter period as the Fund has been in operation).

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Funds benchmark. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The S&P 500® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poors Corporation (S&P) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $2 billion to $401.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.  <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 8.22%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 7.01%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative100false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse4false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003691Member_custom_C000010331Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseNova Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003691Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010331Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Nova Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus101true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]102false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)103false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees104false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]262false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index, or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poors Corporation (S&P) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $2 billion to $401.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index, or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poors Corporation (S&P) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $2 billion to $401.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative335false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse22false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000012221Member_custom_C000033370Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseS&P 500 Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000012221Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000033370Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0S&P 500 Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus336true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]337false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)338false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075[1]falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees339false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025[1]falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Following the bar chart, disclose the Fund's highest and lowest return for a quarter during the 10 years or other period of the bar chart. When a Multiple Class Fund offers more than one Class in the prospectus, provide annual total returns in the bar chart for only one of those Classes. The Fund can select which Class to include (e.g., the oldest Class, the Class with the greatest net assets).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.   Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index.   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The S&P 500® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poors Corporation (S&P) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $2 billion to $401.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 11pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 8.22%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 7.01%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.   Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index.   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]500false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The S&P 500® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poors Corporation (S&P) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $2 billion to $401.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.    <table cellspacing="0" cellpadding="0" style="font: 11pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 8.22%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 7.01%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative542false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse36false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003692Member_custom_C000010335Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInverse S&P 500 Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003692Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010335Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Inverse S&P 500 Strategy Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus543true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]544false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)545false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00900.0090falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees546false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses600false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue343343USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain exposure to international companies included in the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The NASDAQ-100 Index® is a modified capitalization-weighted index composed of 100 of the largest non-financial companies listed on The Nasdaq Stock Market with capitalizations ranging from $4.5 billion to $372.2 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. Currently, the NASDAQ-100 Index® is concentrated in technology companies. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Industry and Technology Sector Concentration RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely in response to such events.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correspond to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain exposure to international companies included in the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The NASDAQ-100 Index® is a modified capitalization-weighted index composed of 100 of the largest non-financial companies listed on The Nasdaq Stock Market with capitalizations ranging from $4.5 billion to $372.2 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. Currently, the NASDAQ-100 Index® is concentrated in technology companies. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Industry and Technology Sector Concentration RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely in response to such events.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correspond to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative776false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse54false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003693Member_custom_C000010339Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseNASDAQ-100 Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003693Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010339Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0NASDAQ-100 Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus777true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]778false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)779false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees780false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain inverse exposure to international companies included in the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The NASDAQ-100 Index® is a modified capitalization-weighted index composed of 100 of the largest non-financial companies listed on The Nasdaq Stock Market with capitalizations ranging from $4.5 billion to $372.2 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. Currently, the NASDAQ-100 Index® is concentrated in technology companies. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 9.10%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 10.66%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Industry and Technology Sector Concentration RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely in response to such events. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.   Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index.   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain inverse exposure to international companies included in the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The NASDAQ-100 Index® is a modified capitalization-weighted index composed of 100 of the largest non-financial companies listed on The Nasdaq Stock Market with capitalizations ranging from $4.5 billion to $372.2 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. Currently, the NASDAQ-100 Index® is concentrated in technology companies. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index. <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 9.10%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 10.66%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Industry and Technology Sector Concentration RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely in response to such events.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]1167false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark for mid-cap securities on a daily basis.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 447% of the average value of its portfolio. The Funds portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Funds portfolio turnover rate might be significantly higher.falsefalsefalsenonnum:textBlockItemTypenaDisclose the portfolio turnover rate provided in response to Item 14(a) for the most recent fiscal year (or for such shorter period as the Fund has been in operation).

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Funds exposure to 150% of the underlying index. As a result, the Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies included in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400® Index is a modified capitalization-weighted index composed of 400 mid-cap stocks chosen by S&P for market size, liquidity, and industry group representation. The S&P MidCap 400® Index covers approximately 7% of the U.S. equities market and generally represents mid-capitalization companies with capitalizations ranging from $487.9 million to $17.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.00%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.91%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]1211false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark for mid-cap securities on a daily basis.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Funds exposure to 150% of the underlying index. As a result, the Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies included in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400® Index is a modified capitalization-weighted index composed of 400 mid cap stocks chosen by S&P for market size, liquidity, and industry group representation. The S&P MidCap 400® Index covers approximately 7% of the U.S. equities market and generally represents mid-capitalization companies with capitalizations ranging from $487.9 million to $17.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.  <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.00%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.91%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative1254false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse90false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003685Member_custom_C000010311Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseMid-Cap 1.5x Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003685Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010311Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Mid-Cap 1.5x Strategy Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus1255true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]1256false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)1257false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00900.0090falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees1258false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]1379false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The S&P MidCap 400® Index is a modified capitalization-weighted index composed of 400 mid-cap stocks chosen by S&P for market size, liquidity, and industry group representation. The S&P MidCap 400® Index covers approximately 7% of the U.S. equities market and generally represents mid-capitalization companies with capitalizations ranging from $487.9 million to $17.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.00%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.91%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.   Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index.   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The S&P MidCap 400® Index is a modified capitalization-weighted index composed of 400 mid-cap stocks chosen by S&P for market size, liquidity, and industry group representation. The S&P MidCap 400® Index covers approximately 7% of the U.S. equities market and generally represents mid-capitalization companies with capitalizations ranging from $487.9 million to $17.7 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index. <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.00%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.91%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative1464false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse104false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003771Member_custom_C000010454Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInverse Mid-Cap Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003771Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010454Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Inverse Mid-Cap Strategy Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus1465true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]1466false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)1467false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00900.0090falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees1468false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]1590false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark for small-cap securities on a daily basis.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]1602false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Funds exposure to 150% of the underlying index. As a result, the Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform similarly to the securities of companies included in the underlying index. The Russell 2000® Index is composed of the 2,000 smallest companies in the Russell 3000® Index, representing approximately 10% of the Russell 3000® total market capitalization and consisting of capitalizations ranging from $22.4 million to $5.8 billion as of June 30, 2013. The Russell 3000® Index is composed of the 3,000 largest U.S. companies ranked by total market capitalization, representing approximately 98% of the U.S. investable equity market. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases.  Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.69%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.77%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.  <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif; width: 100%; background-color: white; border-collapse: collapse"> <tr> <td style="width: 3%"> </td> <td style="vertical-align: bottom; width: 1%"> </td> <td> </td> <td style="vertical-align: bottom; width: 1%"> </td> <td style="width: 94%"> </td></tr> </table> Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]1634false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark for small-cap securities on a daily basis.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Funds exposure to 150% of the underlying index. As a result, the Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform similarly to the securities of companies included in the underlying index. The Russell 2000® Index is composed of the 2,000 smallest companies in the Russell 3000® Index, representing approximately 10% of the Russell 3000® total market capitalization and consisting of capitalizations ranging from $22.4 million to $5.8 billion as of June 30, 2013. The Russell 3000® Index is composed of the 3,000 largest U.S. companies ranked by total market capitalization, representing approximately 98% of the U.S. investable equity market. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.69%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.77%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Russell 2000® Index is composed of the 2,000 smallest companies in the Russell 3000® Index, representing approximately 10% of the Russell 3000® total market capitalization and consisting of capitalizations ranging from $22.4 million to $5.8 billion as of June 30, 2013. The Russell 3000® Index is composed of the 3,000 largest U.S. companies ranked by total market capitalization, representing approximately 98% of the U.S. investable equity market. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Russell 2000® Index is composed of the 2,000 smallest companies in the Russell 3000® Index, representing approximately 10% of the Russell 3000® total market capitalization and consisting of capitalizations ranging from $22.4 million to $5.8 billion as of June 30, 2013. The Russell 3000® Index is composed of the 3,000 largest U.S. companies ranked by total market capitalization, representing approximately 98% of the U.S. investable equity market. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]1862false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]1863false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative1889false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse132false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000012222Member_custom_C000033373Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseRussell 2000 Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000012222Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000033373Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Russell 2000 Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus1890true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]1891false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)1892false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075[1]falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees1893false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025[1]falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]2014false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The Russell 2000® Index is composed of the 2,000 smallest companies in the Russell 3000® Index, representing approximately 10% of the Russell 3000® total market capitalization and consisting of capitalizations ranging from $22.4 million to $5.8 billion as of June 30, 2013. The Russell 3000® Index is composed of the 3,000 largest U.S. companies ranked by total market capitalization, representing approximately 98% of the U.S. investable equity market. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.69%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.77%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative2052false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse145false USDtruefalse$AsOf2013-07-29_custom_ProspectusTwoMember_custom_S000003772Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInverse Russell 2000 Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003772Memberdei_LegalEntityAxisexplicitMemberfalsefalseA-Class, C-Class and Institutional Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusTwoMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Inverse Russell 2000 Strategy Fund | A-Class, C-Class and Institutional Class Shares Prospectus2053true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]2054false 2rr_RiskReturnHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Inverse Russell 2000® Strategy Fundfalsefalsefalsexbrli:stringItemTypestringRisk/Return Summary Investment Objectives/Goals Include the following information, in plain English under rule 421(d) under the Securities Act, in the order and subject matter indicatedReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 2 false0Risk/Return [Heading]2055false 2rr_ObjectiveHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00INVESTMENT OBJECTIVEfalsefalsefalsexbrli:stringItemTypestringInvestment Objectives/Goals.

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.   Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the underlying index.   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]2057false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The Russell 2000® Index is composed of the 2,000 smallest companies in the Russell 3000® Index, representing approximately 10% of the Russell 3000® total market capitalization and consisting of capitalizations ranging from $22.4 million to $5.8 billion as of June 30, 2013. The Russell 3000® Index is composed of the 3,000 largest U.S. companies ranked by total market capitalization, representing approximately 98% of the U.S. investable equity market. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Correlation and Compounding Risk A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index, before accounting for fees and Fund expenses.   Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases.   Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.  <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 10.69%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 8.77%.   Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]2235false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500 Pure Growth Index is narrow in focus, containing only those S&P 500® companies with strong growth characteristics. As of June 30, 2013, the S&P 500 Pure Growth Index included companies with capitalizations ranging from $3.4 billion to $372.2 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Growth Stocks RiskGrowth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]2280false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500 Pure Growth Index is narrow in focus, containing only those S&P 500® companies with strong growth characteristics. As of June 30, 2013, the S&P 500 Pure Growth Index included companies with capitalizations ranging from $3.4 billion to $372.2 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Growth Stocks RiskGrowth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative2308false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse160false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003689Member_custom_C000010323Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseS&P 500 Pure Growth Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003689Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010323Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0S&P 500 Pure Growth Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus2309true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]2310false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)2311false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees2312false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500 Pure Value Index is narrow in focus, containing only those S&P 500® companies with strong value characteristics. As of June 30, 2013, the S&P 500 Pure Value Index included companies with capitalizations ranging from $2 billion to $276.6 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.   Value Stocks RiskValue stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]2489false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500 Pure Value Index is narrow in focus, containing only those S&P 500® companies with strong value characteristics. As of June 30, 2013, the S&P 500 Pure Value Index included companies with capitalizations ranging from $2 billion to $276.6 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Value Stocks RiskValue stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

If extraordinary expenses were incurred that materially affected the Fund's "Other Expenses," disclose in a footnote to the table what "Other Expenses" would have been had the extraordinary expenses been included.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph c -Clause i false0Other Expenses2563false 2rr_ExpensesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.02260.0226falsefalsefalserr:NonNegativePure4TypepureTotal Annual Fund Operating Expenses. If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses2564false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue329329USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

The following Instructions apply to New Funds.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 1 -Subparagraph d false0Expense [Heading]2644false 2rr_ExpenseNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.falsefalsefalsenonnum:textBlockItemTypenaThis table describes the fees and expenses that you may pay if you buy and hold shared of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $[_____] in [name of fund family] funds. Include the narrative explanations in the order indicated. A Fund may modify the narrative explanations if the explanation contains comparable information to that shown. The narrative explanation regarding sales charge discounts is only required by a Fund that offers such discounts and should specify the minimum level of investment required to qualify for a discount. Modify the narrative explanation to state that Fund shares are sold on a national securities exchange at the end of the time periods indicated, and that brokerage commissions for buying and selling Fund shares through a broker are not reflected.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 1 -Subparagraph b false0Expense Narrative [Text Block]2645false 2rr_ShareholderFeesCaptionrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00SHAREHOLDER FEES (fees paid directly from your investment)falsefalsefalsexbrli:stringItemTypestringShareholder Fees (fees paid directly from your investment).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 false0Shareholder Fees Caption [Text]2646false 2rr_OperatingExpensesCaptionrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)falsefalsefalsexbrli:stringItemTypestringAnnual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investment)Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 7 false0Operating Expenses Caption [Text]2647false 2rr_PortfolioTurnoverHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PORTFOLIO TURNOVERfalsefalsefalsexbrli:stringItemTypestringDisclose the portfolio turnover rate provided in response to Item 14(a) for the most recent fiscal year (or for such shorter period as the Fund has been in operation).

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 188% of the average value of its portfolio. The Funds portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Funds portfolio turnover rate might be significantly higher.falsefalsefalsenonnum:textBlockItemTypenaDisclose the portfolio turnover rate provided in response to Item 14(a) for the most recent fiscal year (or for such shorter period as the Fund has been in operation).

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]2653false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400 Pure Growth Index is narrow in focus, containing only those S&P MidCap 400® companies with strong growth characteristics. As of June 30, 2013, the S&P MidCap 400 Pure Growth Index included companies with capitalizations ranging from $1.3 billion to $17.7 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Growth Stocks RiskGrowth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400 Pure Growth Index is narrow in focus, containing only those S&P MidCap 400® companies with strong growth characteristics. As of June 30, 2013, the S&P MidCap 400 Pure Growth Index included companies with capitalizations ranging from $1.3 billion to $17.7 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Growth Stocks RiskGrowth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]2863false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400 Pure Value Index is narrow in focus, containing only those S&P MidCap 400® companies with strong value characteristics. As of June 30, 2013, the S&P MidCap 400 Pure Value Index included companies with capitalizations ranging from $572.2 million to $7.2 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.   Value Stocks RiskValue stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400 Pure Value Index is narrow in focus, containing only those S&P MidCap 400® companies with strong value characteristics. As of June 30, 2013, the S&P MidCap 400 Pure Value Index included companies with capitalizations ranging from $572.2 million to $7.2 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Value Stocks RiskValue stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative2937false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse202false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003769Member_custom_C000010448Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseS&P MidCap 400 Pure Value Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003769Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010448Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0S&P MidCap 400 Pure Value Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus2938true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]2939false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)2940false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees2941false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P SmallCap 600 Pure Growth Index is narrow in focus, containing only those S&P SmallCap 600® companies with strong growth characteristics. As of June 30, 2013, the S&P SmallCap 600 Pure Growth Index included companies with capitalizations ranging from $145.3 million to $4.1 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Growth Stocks RiskGrowth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P SmallCap 600 Pure Growth Index is narrow in focus, containing only those S&P SmallCap 600® companies with strong growth characteristics. As of June 30, 2013, the S&P SmallCap 600 Pure Growth Index included companies with capitalizations ranging from $145.3 million to $4.1 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Growth Stocks RiskGrowth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]3286false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P SmallCap 600 Pure Value Index is narrow in focus, containing only those S&P SmallCap 600® companies with strong value characteristics. As of June 30, 2013, the S&P SmallCap 600 Pure Value Index included companies with capitalizations ranging from $126.5 million to $3 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.   Value Stocks RiskValue stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]3332false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P SmallCap 600 Pure Value Index is narrow in focus, containing only those S&P SmallCap 600® companies with strong value characteristics. As of June 30, 2013, the S&P SmallCap 600 Pure Value Index included companies with capitalizations ranging from $126.5 million to $3 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]3333false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]3334false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Value Stocks RiskValue stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative3360false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse230false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003760Member_custom_C000010429Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseS&P SmallCap 600 Pure Value Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003760Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010429Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0S&P SmallCap 600 Pure Value Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus3361true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]3362false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)3363false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees3364false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Banking Companies that have small to mid-sized capitalizations. Banking Companies are engaged in accepting deposits and making commercial and consumer loans and include state chartered banks, savings and loan institutions, and banks that are members of the Federal Reserve System. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Banking Companies and U.S. government securities. Under U.S. Securities and Exchange Commission regulations, the Fund may not invest more than 5% of its total assets in the equity securities of any company that derives more than 15% of its revenues from brokerage or investment management activities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the banking sector and, therefore, may be concentrated in an industry or group of industries within the banking sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Banking Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the banking sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Banking Companies also may fluctuate widely in response to such events.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Banking Companies that have small to mid-sized capitalizations. Banking Companies are engaged in accepting deposits and making commercial and consumer loans and include state chartered banks, savings and loan institutions, and banks that are members of the Federal Reserve System. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Banking Companies and U.S. government securities. Under U.S. Securities and Exchange Commission regulations, the Fund may not invest more than 5% of its total assets in the equity securities of any company that derives more than 15% of its revenues from brokerage or investment management activities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the banking sector and, therefore, may be concentrated in an industry or group of industries within the banking sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Banking Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the banking sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Banking Companies also may fluctuate widely in response to such events. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement.

A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative3572false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse244false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003683Member_custom_C000010304Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseBanking Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003683Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010304Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Banking Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus3573true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]3574false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)3575false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees3576false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses3634false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Basic Materials Companies that have small to mid-sized capitalizations. Basic Materials Companies are engaged in the manufacture, mining, processing, or distribution of raw materials and intermediate goods used in the industrial sector, and may be involved in the production and transportation of metals, textiles, and wood products. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Basic Materials Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the basic materials sector and, therefore, may be concentrated in an industry or group of industries within the basic materials sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Basic Materials Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the basic materials sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Basic Materials Companies also may fluctuate widely in response to such events.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Basic Materials Companies that have small to mid-sized capitalizations. Basic Materials Companies are engaged in the manufacture, mining, processing, or distribution of raw materials and intermediate goods used in the industrial sector, and may be involved in the production and transportation of metals, textiles, and wood products. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Basic Materials Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the basic materials sector and, therefore, may be concentrated in an industry or group of industries within the basic materials sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Basic Materials Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the basic materials sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Basic Materials Companies also may fluctuate widely in response to such events. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative3809false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse262false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003810Member_custom_C000010627Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseBasic Materials Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003810Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010627Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Basic Materials Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus3810true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]3811false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)3812false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees3813false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Biotechnology Companies that have small to mid-sized capitalizations. Biotechnology Companies are engaged in the research, development, and manufacture of various biotechnological products, services, and processes; manufacture and/or distribute biotechnological and biomedical products, including devices and instruments; provide or benefit significantly from scientific and technological advances in biotechnology; or provide processes or services instead of, or in addition to, products. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Biotechnology Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the biotechnology sector and, therefore, may be concentrated in an industry or group of industries within the biotechnology sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Biotechnology Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the biotechnology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Biotechnology Companies also may fluctuate widely in response to such events.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Biotechnology Companies that have small to mid-sized capitalizations. Biotechnology Companies are engaged in the research, development, and manufacture of various biotechnological products, services, and processes; manufacture and/or distribute biotechnological and biomedical products, including devices and instruments; provide or benefit significantly from scientific and technological advances in biotechnology; or provide processes or services instead of, or in addition to, products. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Biotechnology Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the biotechnology sector and, therefore, may be concentrated in an industry or group of industries within the biotechnology sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Biotechnology Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the biotechnology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Biotechnology Companies also may fluctuate widely in response to such events. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative4046false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse280false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003802Member_custom_C000010595Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseBiotechnology Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003802Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010595Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Biotechnology Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus4047true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]4048false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)4049false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees4050false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Consumer Products Companies that have small to mid-sized capitalizations. Consumer Products Companies include companies that manufacture wholesale or retail food, staple retail products and non-durable goods such as beverages, tobacco, household and personal care products. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Consumer Products Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the consumer products sector and, therefore, may be concentrated in an industry or group of industries within the consumer products sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Consumer Products Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the consumer products sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Consumer Products Companies also may fluctuate widely in response to such events.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Consumer Products Companies that have small to mid-sized capitalizations. Consumer Products Companies include companies that manufacture wholesale or retail food, staple retail products and non-durable goods such as beverages, tobacco, household and personal care products. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Consumer Products Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the consumer products sector and, therefore, may be concentrated in an industry or group of industries within the consumer products sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Consumer Products Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the consumer products sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Consumer Products Companies also may fluctuate widely in response to such events. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative4283false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse298false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003811Member_custom_C000010631Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseConsumer Products Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003811Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010631Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Consumer Products Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus4284true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]4285false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)4286false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees4287false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Fund will invest to a significant extent in the securities of Electronics Companies that have small to mid-sized capitalizations. Electronics Companies include companies involved in the manufacture and development of semiconductors, connectors, printed circuit boards and other components; equipment vendors to electronic component manufacturers; electronic component distributors; electronic instruments and electronic systems vendors; and also include companies involved in all aspects of the electronics business and in new technologies or specialty areas. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Electronics Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the electronics sector and, therefore, may be concentrated in an industry or group of industries within the electronics sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Electronics Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the electronics sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Electronics Companies also may fluctuate widely in response to such events.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Electronics Companies that have small to mid-sized capitalizations. Electronics Companies include companies involved in the manufacture and development of semiconductors, connectors, printed circuit boards and other components; equipment vendors to electronic component manufacturers; electronic component distributors; electronic instruments and electronic systems vendors; and also include companies involved in all aspects of the electronics business and in new technologies or specialty areas. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Electronics Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the electronics sector and, therefore, may be concentrated in an industry or group of industries within the electronics sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Electronics Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the electronics sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Electronics Companies also may fluctuate widely in response to such events. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative4520false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse316false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003803Member_custom_C000010599Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseElectronics Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003803Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010599Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Electronics Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus4521true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]4522false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)4523false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees4524false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses4583false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Energy Companies that have small to mid-sized capitalizations. Energy Companies are involved in all aspects of the energy industry, including the conventional areas of oil, gas, electricity, and coal, and alternative sources of energy such as nuclear, geothermal, oil shale, and solar power, and include companies that produce, transmit, market, distribute or measure energy; companies involved in providing products and services to companies in the energy field; and companies involved in the exploration of new sources of energy, conservation, and energy-related pollution control. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Energy Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the energy sector and, therefore, may be concentrated in an industry or group of industries within the energy sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Energy Sector RiskTo the extent that the Funds investments are exposed to the energy sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Energy Companies also may fluctuate widely in response to such events.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Energy Companies that have small to mid-sized capitalizations. Energy Companies are involved in all aspects of the energy industry, including the conventional areas of oil, gas, electricity, and coal, and alternative sources of energy such as nuclear, geothermal, oil shale, and solar power, and include companies that produce, transmit, market, distribute or measure energy; companies involved in providing products and services to companies in the energy field; and companies involved in the exploration of new sources of energy, conservation, and energy-related pollution control. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Energy Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the energy sector and, therefore, may be concentrated in an industry or group of industries within the energy sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Energy Sector RiskTo the extent that the Funds investments are exposed to the energy sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Energy Companies also may fluctuate widely in response to such events. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative4758false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse334false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003806Member_custom_C000010611Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseEnergy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003806Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010611Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Energy Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus4759true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]4760false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)4761false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees4762false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses4821false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Energy Services Companies that have small to mid-sized capitalizations. Energy Services Companies are engaged in one or more businesses in the energy services field, including those that provide services and equipment to companies engaged in the production, refinement or distribution of oil, gas, electricity, and coal; companies involved with the production and development of newer sources of energy such as nuclear, geothermal, oil shale, and solar power; companies involved with onshore or offshore drilling; companies involved in production and well maintenance; companies involved in exploration engineering, data and technology; companies involved in energy transport; and companies involved in equipment and plant design or construction. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Energy Services Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the energy services sector and, therefore, may be concentrated in an industry or group of industries within the energy services sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Energy Services Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the energy services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Energy Services Companies also may fluctuate widely in response to such events.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Energy Services Companies that have small to mid-sized capitalizations. Energy Services Companies are engaged in one or more businesses in the energy services field, including those that provide services and equipment to companies engaged in the production, refinement or distribution of oil, gas, electricity, and coal; companies involved with the production and development of newer sources of energy such as nuclear, geothermal, oil shale, and solar power; companies involved with onshore or offshore drilling; companies involved in production and well maintenance; companies involved in exploration engineering, data and technology; companies involved in energy transport; and companies involved in equipment and plant design or construction. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Energy Services Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the energy services sector and, therefore, may be concentrated in an industry or group of industries within the energy services sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Energy Services Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the energy services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Energy Services Companies also may fluctuate widely in response to such events. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative4996false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse352false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003801Member_custom_C000010591Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseEnergy Services Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003801Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010591Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Energy Services Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus4997true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]4998false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)4999false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees5000false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses5059false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Fund will invest to a significant extent in the securities of Financial Services Companies that have small to mid-sized capitalizations. Financial Service Companies include commercial banks, savings and loan associations, insurance companies, brokerage companies and real-estate investment trusts. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Financial Services Companies and U.S. government securities. Under U.S. Securities and Exchange Commission regulations, the Fund may not invest more than 5% of its total assets in the equity securities of any company that derives more than 15% of its revenues from brokerage or investment management activities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the financial services sector and, therefore, may be concentrated in an industry or group of industries within the financial services sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Financial Services Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the financial services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Financial Services Companies also may fluctuate widely in response to such events.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Financial Services Companies that have small to mid-sized capitalizations. Financial Service Companies include commercial banks, savings and loan associations, insurance companies, brokerage companies and real-estate investment trusts. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Financial Services Companies and U.S. government securities. Under U.S. Securities and Exchange Commission regulations, the Fund may not invest more than 5% of its total assets in the equity securities of any company that derives more than 15% of its revenues from brokerage or investment management activities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the financial services sector and, therefore, may be concentrated in an industry or group of industries within the financial services sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Financial Services Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the financial services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Financial Services Companies also may fluctuate widely in response to such events. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative5234false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse370false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003807Member_custom_C000010615Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseFinancial Services Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003807Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010615Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Financial Services Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus5235true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]5236false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)5237false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees5238false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses5297false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue339339USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Health Care Companies that have small to mid-sized capitalizations. Health Care Companies include pharmaceutical companies, companies involved in the research and development of pharmaceutical products and services, companies involved in the operation of health care facilities, and other companies involved in the design, manufacture, or sale of health care related products or services. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Health Care Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the health care sector and, therefore, may be concentrated in an industry or group of industries within the health care sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Health Care Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the health care sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Health Care Companies also may fluctuate widely in response to such events.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Health Care Companies that have small to mid-sized capitalizations. Health Care Companies include pharmaceutical companies, companies involved in the research and development of pharmaceutical products and services, companies involved in the operation of health care facilities, and other companies involved in the design, manufacture, or sale of health care related products or services. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Health Care Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the health care sector and, therefore, may be concentrated in an industry or group of industries within the health care sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Health Care Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the health care sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Health Care Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative5472false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse388false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003808Member_custom_C000010619Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseHealth Care Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003808Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010619Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Health Care Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus5473true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]5474false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)5475false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees5476false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses5535false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Internet Companies that have small to mid-sized capitalizations. Internet Companies are involved in all aspects of research, design development, manufacturing or distribution of products or services for use with the Internet or Internet related businesses. Such companies may provide information or entertainment services over the Internet; sell or distribute goods and services over the Internet; provide infrastructure systems or otherwise provide hardware, software or support that impacts Internet commerce; or provide Internet access to consumers and businesses. Internet companies also may include companies that provide Intranet and Extranet services. The Fund will maintain broad representation of the various industries in the Internet sector. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Internet Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the Internet sector and, therefore, may be concentrated in an industry or group of industries within the Internet sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   Internet Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the Internet sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Internet Companies also may fluctuate widely in response to such events.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.     Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Internet Companies that have small to mid-sized capitalizations. Internet Companies are involved in all aspects of research, design development, manufacturing or distribution of products or services for use with the Internet or Internet related businesses. Such companies may provide information or entertainment services over the Internet; sell or distribute goods and services over the Internet; provide infrastructure systems or otherwise provide hardware, software or support that impacts Internet commerce; or provide Internet access to consumers and businesses. Internet companies also may include companies that provide Intranet and Extranet services. The Fund will maintain broad representation of the various industries in the Internet sector. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Internet Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the Internet sector and, therefore, may be concentrated in an industry or group of industries within the Internet sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Internet Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the Internet sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Internet Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative5710false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse406false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003804Member_custom_C000010603Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInternet Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003804Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010603Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Internet Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus5711true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]5712false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)5713false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees5714false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses5773false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Fund will invest to a significant extent in the securities of Leisure Companies that have small to mid-sized capitalizations. Leisure Companies are engaged in the design, production, or distribution of goods or services in the leisure industries. Leisure Companies include hotels and resorts, restaurants, casinos, radio and television broadcasting and advertising companies, motion picture production companies, entertainment software companies, toys and sporting goods manufacturers, musical recording companies, alcohol and tobacco companies, and publishing companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Leisure Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the leisure sector and, therefore, may be concentrated in an industry or group of industries within the leisure sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Leisure Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the leisure sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Leisure Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Leisure Companies that have small to mid-sized capitalizations. Leisure Companies are engaged in the design, production, or distribution of goods or services in the leisure industries. Leisure Companies include hotels and resorts, restaurants, casinos, radio and television broadcasting and advertising companies, motion picture production companies, entertainment software companies, toys and sporting goods manufacturers, musical recording companies, alcohol and tobacco companies, and publishing companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Leisure Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the leisure sector and, therefore, may be concentrated in an industry or group of industries within the leisure sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Leisure Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the leisure sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Leisure Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative5948false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse424false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003812Member_custom_C000010635Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseLeisure Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003812Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010635Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Leisure Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus5949true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]5950false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)5951false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees5952false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses6011false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

The Fund will invest to a significant extent in the securities of Precious Metals Companies that have small to mid-sized capitalizations. Precious metals include gold, silver, platinum and other precious metals. Precious Metals Companies include precious metal manufacturers; distributors of precious metal products, such as jewelry, metal foil or bullion; mining and geological exploration companies; and companies that provide services to Precious Metals Companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Precious Metals Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the precious metals sector and, therefore, may be concentrated in an industry or group of industries within the precious metals sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Precious Metals Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the precious metals sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Precious Metals Companies also may fluctuate widely in response to such events. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Precious Metals Companies that have small to mid-sized capitalizations. Precious metals include gold, silver, platinum and other precious metals. Precious Metals Companies include precious metal manufacturers; distributors of precious metal products, such as jewelry, metal foil or bullion; mining and geological exploration companies; and companies that provide services to Precious Metals Companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Precious Metals Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the precious metals sector and, therefore, may be concentrated in an industry or group of industries within the precious metals sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Precious Metals Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the precious metals sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Precious Metals Companies also may fluctuate widely in response to such events. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative6186false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse442false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003798Member_custom_C000010579Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalsePrecious Metals Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003798Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010579Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Precious Metals Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus6187true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]6188false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)6189false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees6190false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Retailing Companies that have small to mid-sized capitalizations. Retailing Companies include drug and department stores; suppliers of goods and services for homes, home improvements and yards; clothing, jewelry, electronics and computer retailers; warehouse membership clubs; mail order operations; and companies involved in alternative selling methods. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Retailing Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the retailing sector and, therefore, may be concentrated in an industry or group of industries within the retailing sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Retailing Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the retailing sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of the Retailing Companies also may fluctuate widely in response to such events. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Retailing Companies that have small to mid-sized capitalizations. Retailing Companies include drug and department stores; suppliers of goods and services for homes, home improvements and yards; clothing, jewelry, electronics and computer retailers; warehouse membership clubs; mail order operations; and companies involved in alternative selling methods. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Retailing Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the retailing sector and, therefore, may be concentrated in an industry or group of industries within the retailing sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Retailing Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the retailing sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of the Retailing Companies also may fluctuate widely in response to such events. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative6424false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse460false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003813Member_custom_C000010639Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseRetailing Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003813Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010639Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Retailing Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus6425true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]6426false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)6427false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees6428false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses6487false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Technology Companies that have small to mid-sized capitalizations. Technology Companies are companies that the Advisor believes have, or will develop, products, processes, or services that will provide technological advances and improvements. These companies may include, for example, companies that develop, produce or distribute products or services in the computer, semiconductor, electronics and communications sectors. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Technology Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the technology sector and, therefore, may be concentrated in an industry or group of industries within the technology sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Technology Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Technology Companies also may fluctuate widely in response to such events. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Technology Companies that have small to mid-sized capitalizations. Technology Companies are companies that the Advisor believes have, or will develop, products, processes, or services that will provide technological advances and improvements. These companies may include, for example, companies that develop, produce or distribute products or services in the computer, semiconductor, electronics and communications sectors. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Technology Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the technology sector and, therefore, may be concentrated in an industry or group of industries within the technology sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Technology Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Technology Companies also may fluctuate widely in response to such events. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative6662false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse478false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003809Member_custom_C000010623Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseTechnology Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003809Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010623Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Technology Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus6663true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]6664false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)6665false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees6666false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses6725false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue338338USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Telecommunications Companies that have small to mid-sized capitalizations. Telecommunications Companies include traditional and wireless telephone services or equipment providers, Internet equipment and service providers, and fiber-optics. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Telecommunications Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the telecommunications sector and, therefore, may be concentrated in an industry or group of industries within the telecommunications sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Telecommunications Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the telecommunications sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of the Telecommunications Companies also may fluctuate widely in response to such events. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Telecommunications Companies that have small to mid-sized capitalizations. Telecommunications Companies include traditional and wireless telephone services or equipment providers, Internet equipment and service providers, and fiber-optics. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Telecommunications Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the telecommunications sector and, therefore, may be concentrated in an industry or group of industries within the telecommunications sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Telecommunications Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the telecommunications sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of the Telecommunications Companies also may fluctuate widely in response to such events. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative6900false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse496false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003799Member_custom_C000010583Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseTelecommunications Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003799Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010583Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Telecommunications Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus6901true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]6902false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)6903false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees6904false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses6963false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue339339USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Transportation Companies that have small to mid-sized capitalizations. Transportation Companies may include, for example, companies involved in the movement of freight or people, such as airline, railroad, ship, truck and bus companies; equipment manufacturers; parts suppliers; and companies involved in leasing, maintenance, and transportation-related services. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Transportation Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the transportation sector and, therefore, may be concentrated in an industry or group of industries within the transportation sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Transportation Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the transportation sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Transportation Companies also may fluctuate widely in response to such events.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Transportation Companies that have small to mid-sized capitalizations. Transportation Companies may include, for example, companies involved in the movement of freight or people, such as airline, railroad, ship, truck and bus companies; equipment manufacturers; parts suppliers; and companies involved in leasing, maintenance, and transportation-related services. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Transportation Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the transportation sector and, therefore, may be concentrated in an industry or group of industries within the transportation sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Transportation Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the transportation sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Transportation Companies also may fluctuate widely in response to such events.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative7138false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse514false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003800Member_custom_C000010587Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseTransportation Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003800Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010587Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Transportation Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus7139true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]7140false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)7141false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees7142false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

The Fund will invest to a significant extent in the securities of Utilities Companies that have small to mid-sized capitalizations. Utilities Companies may include companies involved in the manufacturing, production, generation, transmission, distribution or sales of gas or electric energy; water supply, waste and sewage disposal; and companies that receive a majority of their revenues from their public utility operations. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Utilities Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the utilities sector and, therefore, may be concentrated in an industry or group of industries within the utilities sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Utilities Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the utilities sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Utilities Companies also may fluctuate widely in response to such events.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective. Utilities Sector RiskTo the extent that the Funds investments are exposed to issuers conducting business in the utilities sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Utilities Companies also may fluctuate widely in response to such events.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative7376false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse532false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003805Member_custom_C000010607Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseUtilities Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003805Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010607Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Utilities Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus7377true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]7378false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)7379false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees7380false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.25x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.25x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program. falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]7531false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Funds exposure to 125% of the underlying index. As a result, the Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain exposure to the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Europe STOXX 50® Index is a capitalization-weighted index composed of 50 European blue chip stocks consisting of capitalizations ranging from $11.4 billion to $110.8 billion as of June 30, 2013. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 125% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 125% of the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="width: 100%;

The underlying indexs highest one-year volatility rate during the five year period is 12.35%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is -5.33%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskIndirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political developments in the U.S. or abroad. In particular, the Fund may have indirect and direct exposure to the euro. The price of the euro has fluctuated widely over the past several years, and volatility has increased in recent months, due, in part, to concern over the sovereign debt levels of certain European Union (EU) members and the potential effect of this debt on the EU members participation in the European Monetary Union and the value of the euro. These and other factors may adversely affect the long-term value of the euro in terms of purchasing power in the future. A decline in the price of the euro may adversely affect the Funds performance. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Geographic Concentration in Europe RiskBecause a significant portion of the Funds investments are concentrated in issuers located in Europe, the Fund is susceptible to loss due to adverse market, political, regulatory, and geographic events affecting the various countries and regions in Europe. The European economy is diverse and includes both large, competitive economies and small, struggling economies. The European economy is vulnerable to decreasing imports or exports, changes in governmental regulations on trade, changes in the exchange rate of the euro and recessions in EU economies. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.25x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.25x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]7588false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Funds exposure to 125% of the underlying index. As a result, the Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain exposure to the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Europe STOXX 50® Index is a capitalization-weighted index composed of 50 European blue chip stocks consisting of capitalizations ranging from $11.4 billion to $110.8 billion as of June 30, 2013. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 125% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 125% of the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Times New Roman, Times, Serif;

The underlying indexs highest one-year volatility rate during the five year period is 12.35%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is -5.33%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskIndirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political developments in the U.S. or abroad. In particular, the Fund may have indirect and direct exposure to the euro. The price of euro has fluctuated widely over the past several years, and volatility has increased in recent months, due, in part, to concern over the sovereign debt levels of certain European Union (EU) members and the potential effect of this debt on the EU members participation in the European Monetary Union and the value of the euro. These and other factors may adversely affect the long-term value of the euro in terms of purchasing power in the future. A decline in the price of the euro may adversely affect the Funds performance. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Geographic Concentration in Europe RiskBecause a significant portion of the Funds investments are concentrated in issuers located in Europe, the Fund is susceptible to loss due to adverse market, political, regulatory, and geographic events affecting the various countries and regions in Europe. The European economy is diverse and includes both large, competitive economies and small, struggling economies. The European economy is vulnerable to decreasing imports or exports, changes in governmental regulations on trade, changes in the exchange rate of the euro and recessions in EU economies. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative7616false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse550false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003695Member_custom_C000010346Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseEurope 1.25x Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003695Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010346Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Europe 1.25x Strategy Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus7617true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]7618false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)7619false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.0090.009falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees7620false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]7738false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain exposure to the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Nikkei 225 Stock Average is a price-weighted average of 225 top-rated Japanese companies listed on the First Section of the Tokyo Stock Exchange that are selected to be both highly liquid and representative of Japans industrial structure. As of June 30, 2013, the Nikkei 225 Stock Average included companies with small, medium and large capitalizations ranging from $290.7 million to $207.9 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]7750false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKS falsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]7751false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="width: 100%;

The underlying indexs highest one-year volatility rate during the five year period is 9.87%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 0.29%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Geographic Concentration in Japan RiskTargeting Japan could hurt the Funds performance if Japans economy performs poorly as a result of political and economic conditions that affect the Japanese market. Japanese stocks tend to be more volatile than their U.S. counterparts, for reasons ranging from political and economic uncertainties, to a higher risk that essential information may be incomplete or erroneous. The Fund may be more volatile than a geographically diversified equity fund. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The following table shows the performance of the H-Class Shares of the Fund as an average over different periods of time in comparison to the performance of a broad-based market index. Effective May 1, 2009, the Fund changed comparative benchmarks from the Topix 100 Index to the Nikkei 225 Stock Average. This change occurred as a result of the Funds change in name and investment strategy. Prior to May 1, 2009, the Funds investment strategy sought to provide 125% exposure to the Topix 100 Index; therefore, the performance and average annual total returns shown below for periods prior to May 1, 2009 may have differed had the Funds current investment strategy, which seeks to provide 200% exposure to the Nikkei 225 Stock Average, been in effect during those periods. The Nikkei 225 Stock Average more appropriately reflects the Funds investment universe. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may invest in American Depositary Receipts (ADRs) to gain exposure to the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Nikkei 225 Stock Average is a price-weighted average of 225 top-rated Japanese companies listed on the First Section of the Tokyo Stock Exchange that are selected to be both highly liquid and representative of Japans industrial structure. As of June 30, 2013, the Nikkei 225 Stock Average included companies with small, medium and large capitalizations ranging from $290.7 million to $207.9 billion. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 9.87%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 0.29%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Geographic Concentration in Japan RiskTargeting Japan could hurt the Funds performance if Japans economy performs poorly as a result of political and economic conditions that affect the Japanese market. Japanese stocks tend to be more volatile than their U.S. counterparts, for reasons ranging from political and economic uncertainties, to a higher risk that essential information may be incomplete or erroneous. The Fund may be more volatile than a geographically diversified equity fund. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The variability of performance over time provides an indication of the risks of investing in the Fund. The following tables show the performance of the A-Class Shares and C-Class Shares of the Fund as an average over different periods of time in comparison to the performance of a broad-based market index. Effective May 1, 2009, the Fund changed comparative benchmarks from the Topix 100 Index to the Nikkei 225 Stock Average. This change occurred as a result of the Funds change in name and investment strategy. Prior to May 1, 2009, the Funds investment strategy sought to provide 125% exposure to the Topix 100 Index; therefore, the performance and average annual total returns shown below for periods prior to May 1, 2009 may have differed had the Funds current investment strategy, which seeks to provide 200% exposure to the Nikkei 225 Stock Average, been in effect during those periods. The Nikkei 225 Stock Average more appropriately reflects the Funds investment universe. The figures in the bar chart and tables assume the reinvestment of dividends and capital gains distributions but do not reflect sales charges. If they did, returns would be lower.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Funds use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. The Fund also may invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The BNY Mellon Emerging Markets 50 ADR Index is a capitalization weighted index comprised of the 50 largest emerging market based ADRs having a free-float market capitalization ranging from approximately $5.5 billion to $223.2 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="width: 100%;

The underlying indexs highest one-year volatility rate during the five year period is 12.63%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is -5.20%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Emerging Markets RiskThe Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Funds use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. The Fund also may invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The BNY Mellon Emerging Markets 50 ADR Index is a capitalization weighted index comprised of the 50 largest emerging market based ADRs having a free-float market capitalization ranging from approximately $5.5 billion to $223.2 billion as of June 30, 2013. To the extent the Funds underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 12.63%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is -5.20%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Emerging Markets RiskThe Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph d false0Total Annual Fund Operating Expenses8055false 2rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue366366USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse leveraged exposure to the underlying index. The Fund also may invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The BNY Mellon Emerging Markets 50 ADR Index is a capitalization weighted index comprised of the 50 largest emerging market based ADRs having a free-float market capitalization ranging from approximately $5.5 billion to $223.2 billion as of June 30, 2013. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the inverse performance of the underlying index. <table cellspacing="0" cellpadding="0" style="width: 100%;

The underlying indexs highest one-year volatility rate during the five year period is 12.63%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is -5.20%. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Emerging Markets RiskThe Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse leveraged exposure to the underlying index. The Fund also may invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The BNY Mellon Emerging Markets 50 ADR Index is a capitalization weighted index comprised of the 50 largest emerging market based ADRs having a free-float market capitalization ranging from approximately $5.5 billion to $223.2 billion as of June 30, 2013. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 12.63%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is -5.20%. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Emerging Markets RiskThe Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative8205false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse592false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000018292Member_custom_C000050427Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInverse Emerging Markets 2x Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000018292Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000050427Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Inverse Emerging Markets 2x Strategy Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus8206true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]8207false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)8208false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.0090.009[1]falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees8209false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025[1]falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]8307false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match the performance of a specific benchmark, before fees and expenses, on a daily basis. The Funds current benchmark is 200% of the performance of the U.S. Dollar Index® (the underlying index).

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $[_____] in [name of fund family] funds. Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Investing in derivative instruments enables the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The U.S. Dollar Index® measures the performance of the U.S. dollar against a basket of foreign currencies that include the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="width: 100%;

The underlying indexs highest one-year volatility rate during the five year period is 4.43%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 2.79%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]8350false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match the performance of a specific benchmark, before fees and expenses, on a daily basis.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

Investing in derivative instruments enables the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The U.S. Dollar Index® measures the performance of the U.S. dollar against a basket of foreign currencies that include the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 4.43%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 2.79%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative8392false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse606false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003775Member_custom_C000010466Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseStrengthening Dollar 2x Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003775Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010466Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Strengthening Dollar 2x Strategy Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus8393true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]8394false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)8395false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.0090.009falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees8396false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]8516false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The U.S. Dollar Index® measures the performance of the U.S. dollar against a basket of foreign currencies that include the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="width: 100%;

The underlying indexs highest one-year volatility rate during the five year period is 4.43%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 2.79%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Funds investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The U.S. Dollar Index® measures the performance of the U.S. dollar against a basket of foreign currencies that include the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the inverse performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The underlying indexs highest one-year volatility rate during the five year period is 4.43%. The underlying indexs annualized performance for the five year period ended June 30, 2013 is 2.79%. Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Leveraging RiskThe Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Status as a Regulated Investment Company RiskThe Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to match that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Real Estate Companies that have small to mid-sized capitalizations. Real Estate Companies, which also include master limited partnerships, are primarily engaged in the ownership, construction, management, financing or sale of residential, commercial or industrial real estate. Real Estate Companies also may include companies whose products and services are related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Real Estate Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the real estate sector and, therefore, may be concentrated in an industry or group of industries within the real estate sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Industry and Real Estate Sector RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are exposed to issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Real Estate Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund will invest to a significant extent in the securities of Real Estate Companies that have small to mid-sized capitalizations. Real Estate Companies, which also include master limited partnerships, are primarily engaged in the ownership, construction, management, financing or sale of residential, commercial or industrial real estate. Real Estate Companies also may include companies whose products and services are related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Real Estate Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the real estate sector and, therefore, may be concentrated in an industry or group of industries within the real estate sector.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]8781false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]8782false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Industry and Real Estate Sector RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are exposed to issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Real Estate Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative8808false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse634false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003773Member_custom_C000010460Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseReal Estate Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003773Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010460Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Real Estate Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus8809true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]8810false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)8811false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00850.0085falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees8812false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correspond to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will likely differ from the return of the Funds benchmark for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.2x) and the cumulative performance of the benchmark (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]8934false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correspond, before fees and expenses, to a benchmark for U.S. government securities on a daily basis. The Funds current benchmark is 120% of the daily price movement of the Long Treasury Bond. The Long Treasury Bond is the U.S. Treasury bond with the longest maturity, which is currently 30 years. The price movement of the Long Treasury Bond is based on the daily price change of the most recently issued Long Treasury Bond. The Fund does not seek to achieve its investment objective over a period of time greater than one day.falsefalsefalsenonnum:textBlockItemTypenaInvestment Objectives/Goals.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Futures and options contracts, and interest rate swaps, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in its benchmark or to securities whose performance is highly correlated to its benchmark. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities issued by the U.S. government (and derivatives thereof). Some of the Funds U.S. government securities, or cash equivalents, will be used to collateralize its derivative positions. The Fund also may invest in zero coupon U.S. Treasury bonds and enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the Long Treasury Bond has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the Long Treasury Bond times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged benchmark fund. In general, particularly during periods of higher benchmark volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) the performance of the Long Treasury Bond; (b) volatility of the Long Treasury Bond; (c) financing rates associated with leverage; (d) other Fund expenses; and (e) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 120% of the performance of the Long Treasury Bond; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 120% of the performance of the Long Treasury Bond. <table cellspacing="0" cellpadding="0" style="width: 100%;

The Long Treasury Bonds highest one-year volatility rate during the five year period is 5.88%. The Long Treasury Bonds annualized performance for the five year period ended June 30, 2013 is 7.58%. The historical volatility and performance of the Long Treasury Bond are not indications of what the Long Treasury Bond volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Leveraging RiskThe Fund achieves leveraged exposure to the Long Treasury Bond through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the Long Treasury Bond. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correspond to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and the Long Treasury Bond, rounding of share prices, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not correspond to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will likely differ from the return of the Funds benchmark for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.2x) and the cumulative performance of the benchmark (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]8977false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correspond, before fees and expenses, to a benchmark for U.S. government securities on a daily basis.

The price movement of the Long Treasury Bond is based on the daily price change of the most recently issued Long Treasury Bond.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Futures and options contracts, and interest rate swaps, if used properly, may enable the Fund to meet its objective by increasing the Funds exposure to the securities included in its benchmark or to securities whose performance is highly correlated to its benchmark. The Funds use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities issued by the U.S. government (and derivatives thereof). Some of the Funds U.S. government securities, or cash equivalents, will be used to collateralize its derivative positions. The Fund also may invest in zero coupon U.S. Treasury bonds and enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the Long Treasury Bond has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Funds performance for periods greater than one day is likely to be either greater than or less than the performance of the Long Treasury Bond times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged benchmark fund. In general, particularly during periods of higher benchmark volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) the performance of the Long Treasury Bond; (b) volatility of the Long Treasury Bond; (c) financing rates associated with leverage; (d) other Fund expenses; and (e) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 120% of the performance of the Long Treasury Bond; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 120% of the performance of the Long Treasury Bond.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The Long Treasury Bonds highest one-year volatility rate during the five year period is 5.88%. The Long Treasury Bonds annualized performance for the five year period ended June 30, 2013 is 7.58%. The historical volatility and performance of the Long Treasury Bond are not indications of what the Long Treasury Bond volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Leveraging RiskThe Fund achieves leveraged exposure to the Long Treasury Bond through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the Long Treasury Bond. Leverage also will have the effect of magnifying tracking error. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correspond to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and the Long Treasury Bond, rounding of share prices, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period longer than a full trading day will be the result of each days compounded returns over the period, which will likely differ from the inverse return of the daily price movement of the benchmark for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the benchmark. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]9174false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide total returns that inversely correlate, before fees and expenses, to the price movements of a benchmark for U.S. Treasury debt instruments or futures contracts on a specified debt instrument on a daily basis. The Funds current benchmark is the daily price movement of the Long Treasury Bond. The Long Treasury Bond is the U.S. Treasury bond with the longest maturity, which is currently 30 years. The price movement of the Long Treasury Bond is based on the daily price change of the most recently issued Long Treasury Bond. The Fund does not seek to achieve its investment objective over a period of time greater than one day.falsefalsefalsenonnum:textBlockItemTypenaInvestment Objectives/Goals.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 1,309% of the average value of its portfolio.

The Fund employs as its investment strategy a program of engaging in short sales and investing to a significant extent in derivative instruments, which primarily consist of futures contracts, interest rate swaps, and options on securities and futures contracts. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to fixed income securities issued by the U.S. government. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the Long Treasury Bond has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the Long Treasury Bond times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) performance of the Long Treasury Bond; (b) volatility of the Long Treasury Bond; (c) financing rates associated with leverage; (d) other Fund expenses; and (e) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the Long Treasury Bond; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the Long Treasury Bond. <table cellspacing="0" cellpadding="0" style="width: 100%;

The historical volatility and performance of the Long Treasury Bond are not indications of what the Long Treasury Bond volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and the Long Treasury Bond, rounding of share prices, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period longer than a full trading day will be the result of each days compounded returns over the period, which will likely differ from the inverse return of the daily price movement of the benchmark for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the benchmark. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

The Funds current benchmark is the daily price movement of the Long Treasury Bond. The Long Treasury Bond is the U.S. Treasury bond with the longest maturity, which is currently 30 years. The price movement of the Long Treasury Bond is based on the daily price change of the most recently issued Long Treasury Bond. The Fund does not seek to achieve its investment objective over a period of time greater than one day.falsefalsefalsenonnum:textBlockItemTypenaInvestment Objectives/Goals.

The Fund employs as its investment strategy a program of engaging in short sales and investing to a significant extent in derivative instruments, which primarily consist of futures contracts, interest rate swaps, and options on securities and futures contracts. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to fixed income securities issued by the U.S. government. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the Long Treasury Bond has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Funds performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the Long Treasury Bond times the stated multiple in the Funds investment objective, before accounting for fees and Fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) performance of the Long Treasury Bond; (b) volatility of the Long Treasury Bond; (c) financing rates associated with leverage; (d) other Fund expenses; and (e) period of time. The chart below illustrates the impact of two principal factorsvolatility and index performanceon Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the Long Treasury Bond; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the Long Treasury Bond.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

The historical volatility and performance of the Long Treasury Bond are not indications of what the Long Treasury Bond volatility and performance will be in the future. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Passive Investment RiskThe Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Tracking Error RiskThe Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and the Long Treasury Bond, rounding of share prices, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative9259false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse666false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000003690Member_custom_C000010327Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInverse Government Long Bond Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000003690Memberdei_LegalEntityAxisexplicitMemberfalsefalseAdvisor Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000010327Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Inverse Government Long Bond Strategy Fund | Advisor Class | Advisor Class, Investor Class and H-Class Shares Prospectus9260true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]9261false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)9262false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00900.0090falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees9263false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]9433false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to gain exposure similar to the total return of the high yield bond market as represented by the global universe (excluding emerging market countries) of fixed rate, non-investment grade debt by investing in credit default swaps, high yield securities, futures and other financial instruments with economic characteristics comparable to that of the high yield bond market as represented by U.S. and Canadian high yield bonds. Generally, high yield bonds, which are also commonly referred to as junk bonds, are those bonds rated BB+ and lower by Standard & Poors Rating Service or Ba1 and lower by Moodys Investor Services, Inc., but may include unrated bonds that the Advisor determines are of similar quality. The Advisor will consider the liquidity, transaction costs and relative value of available investments in seeking to meet the Funds investment objective. The Fund will primarily invest in credit default swaps to gain exposure similar to the high yield bond market. Credit default swaps are instruments which allow for the full or partial transfer of third party credit risk, with respect to a particular entity or entities, from one counterparty to the other. A buyer of credit default swaps is buying credit protection or mitigating credit risk. A seller of credit default swaps is selling credit protection or assuming credit risk. The Fund will normally be a seller of credit protection (assuming credit risk) as it seeks to gain exposure to the high yield bond market, but also may buy credit protection from time to time in order to maintain the appropriate level of exposure to the high yield bond market, such as during times of heavy redemption activity. In addition, the Fund may invest in bond futures for the purpose of managing duration risk. For cash management purposes, the Fund may invest in other fixed income securities and money market instruments. The Fund also may invest in other financial instruments including corporate notes, convertible debt securities, preferred securities and derivatives thereof, as well as other investment companies, including exchange-traded funds (ETFs), unit investment trusts, and closed-end funds, that invest primarily in high yield debt instruments. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments that in combination have economic characteristics similar to the U.S. and Canadian high yield bond markets and/or in high yield debt securities.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Credit Default Swap RiskThe Funds investments in credit default swaps may subject the Fund to greater risks than if the Fund were to invest directly in high yield bonds. When investing in credit default swaps, the Fund is exposed to the credit risk of both the counterparty to the credit default swap and the issuer of the underlying reference obligation. The Fund could realize a loss on its investment if it does not correctly evaluate the creditworthiness of the issuer of the bond or other reference obligation on which the credit default swap is based, as well as the continued creditworthiness of the counterparty. Investments in credit default swaps also are subject to liquidity risk. Credit RiskThe Fund could lose money if the issuer or guarantor of a debt instrument in which it invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives, such as bond futures, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Issuer Specific RiskThe value of a security may increase or decrease for a number of reasons which directly relate to the issuer. For example, with respect to the Fund, perceived poor management performance, financial leverage or reduced demand of the issuers goods or services may contribute to a decrease in the value of a security. A decrease in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the Fund to decrease. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Generally, high yield bonds, which are also commonly referred to as junk bonds, are those bonds rated BB+ and lower by Standard & Poors Rating Service or Ba1 and lower by Moodys Investor Services, Inc., but may include unrated bonds that the Advisor determines are of similar quality. The Advisor will consider the liquidity, transaction costs and relative value of available investments in seeking to meet the Funds investment objective. The Fund will primarily invest in credit default swaps to gain exposure similar to the high yield bond market. Credit default swaps are instruments which allow for the full or partial transfer of third party credit risk, with respect to a particular entity or entities, from one counterparty to the other. A buyer of credit default swaps is buying credit protection or mitigating credit risk. A seller of credit default swaps is selling credit protection or assuming credit risk. The Fund will normally be a seller of credit protection (assuming credit risk) as it seeks to gain exposure to the high yield bond market, but also may buy credit protection from time to time in order to maintain the appropriate level of exposure to the high yield bond market, such as during times of heavy redemption activity. In addition, the Fund may invest in bond futures for the purpose of managing duration risk. For cash management purposes, the Fund may invest in other fixed income securities and money market instruments. The Fund also may invest in other financial instruments including corporate notes, convertible debt securities, preferred securities and derivatives thereof, as well as other investment companies, including exchange-traded funds (ETFs), unit investment trusts, and closed-end funds, that invest primarily in high yield debt instruments. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments that in combination have economic characteristics similar to the U.S. and Canadian high yield bond markets and/or in high yield debt securities.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Credit Default Swap RiskThe Funds investments in credit default swaps may subject the Fund to greater risks than if the Fund were to invest directly in high yield bonds. When investing in credit default swaps, the Fund is exposed to the credit risk of both the counterparty to the credit default swap and the issuer of the underlying reference obligation. The Fund could realize a loss on its investment if it does not correctly evaluate the creditworthiness of the issuer of the bond or other reference obligation on which the credit default swap is based, as well as the continued creditworthiness of the counterparty. Investments in credit default swaps also are subject to liquidity risk. Credit RiskThe Fund could lose money if the issuer or guarantor of a debt instrument in which it invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives, such as bond futures, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Issuer Specific RiskThe value of a security may increase or decrease for a number of reasons which directly relate to the issuer. For example, with respect to the Fund, perceived poor management performance, financial leverage or reduced demand of the issuers goods or services may contribute to a decrease in the value of a security. A decrease in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the Fund to decrease. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse of the return of the high yield bond market for that period. As a consequence, especially in periods of market volatility, the path or trend of the high yield bond market during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the high yield bond market for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the high yield bond market. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risk of shorting and (b) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]9630false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that inversely correlate, before fees and expenses, to the performance of the high yield bond market.falsefalsefalsenonnum:textBlockItemTypenaInvestment Objectives/Goals.

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $[_____] in [name of fund family] funds. Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 0% of the average value of its portfolio. The Funds portfolio turnover rate is calculated without regard to cash instruments or derivatives.

Generally, high yield bonds, which are also commonly referred to as junk bonds, are those bonds rated BB+ and lower by Standard & Poors Rating Service or Ba1 and lower by Moodys Investor Services, Inc., but may include unrated bonds that the Advisor determines are of similar quality. The Advisor will consider the liquidity, transaction costs and relative value of available investments in seeking to meet the Funds objective. The Fund will primarily invest in credit default swaps to gain inverse exposure to the high yield bond market. Credit default swaps are instruments which allow for the full or partial transfer of third party credit risk, with respect to a particular entity or entities, from one counterparty to the other. A buyer of credit default swaps is buying credit protection or mitigating credit risk. A seller of credit default swaps is selling credit protection or assuming credit risk. The Fund will normally be a buyer of credit protection as it seeks to gain inverse exposure to the high yield bond market, but also may sell credit protection (assuming credit risk) from time to time in order to maintain the appropriate level of exposure to the high yield bond market, such as during times of heavy redemption activity. In addition, the Fund may invest in bond futures for the purpose of managing duration risk. For cash management purposes, the Fund may invest in other fixed income securities and money market instruments. The Fund also may invest in other financial instruments including corporate notes, convertible debt securities, preferred securities and derivatives thereof, as well as other investment companies, including exchange-traded funds, unit investment trusts, and closed-end funds, that provide inverse exposure to the high yield debt market. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments that in combination should provide inverse exposure to the U.S. and Canadian high yield bond markets.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the high yield bond market experiences extreme volatility. In addition, as a result of compounding, the Funds performance is likely to be either greater than or less than the inverse performance of the high yield bond market, before accounting for fees and Fund expenses. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Credit Default Swap RiskThe Funds investments in credit default swaps may subject the Fund to greater risks than if the Fund were to invest directly in high yield bonds. When investing in credit default swaps, the Fund is exposed to the credit risk of both the counterparty to the credit default swap and the issuer of the underlying reference obligation. The Fund could realize a loss on its investment if it does not correctly evaluate the creditworthiness of the issuer of the bond or other reference obligation on which the credit default swap is based, as well as the continued creditworthiness of the counterparty. Investments in credit default swaps also are subject to liquidity risk. Credit RiskChanges in an issuers financial strength or in an issuers or debt securitys credit rating may affect a securitys value and thus have an impact on Fund performance. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives, such as bond futures, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Issuer Specific RiskThe value of a security may increase or decrease for a number of reasons which directly relate to the issuer. For example, with respect to the Fund, perceived poor management performance, financial leverage or reduced demand of the issuers goods or services may contribute to a decrease in the value of a security. A decrease in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the Fund to decrease. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives. Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from the inverse of the return of the high yield bond market for that period. As a consequence, especially in periods of market volatility, the path or trend of the high yield bond market during the longer period may be at least as important to the Funds return for the longer period as the cumulative return of the high yield bond market for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -1x) and the cumulative performance of the high yield bond market. The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risk of shorting and (b) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Generally, high yield bonds, which are also commonly referred to as junk bonds, are those bonds rated BB+ and lower by Standard & Poors Rating Service or Ba1 and lower by Moodys Investor Services, Inc., but may include unrated bonds that the Advisor determines are of similar quality. The Advisor will consider the liquidity, transaction costs and relative value of available investments in seeking to meet the Funds objective. The Fund will primarily invest in credit default swaps to gain inverse exposure to the high yield bond market. Credit default swaps are instruments which allow for the full or partial transfer of third party credit risk, with respect to a particular entity or entities, from one counterparty to the other. A buyer of credit default swaps is buying credit protection or mitigating credit risk. A seller of credit default swaps is selling credit protection or assuming credit risk. The Fund will normally be a buyer of credit protection as it seeks to gain inverse exposure to the high yield bond market, but also may sell credit protection (assuming credit risk) from time to time in order to maintain the appropriate level of exposure to the high yield bond market, such as during times of heavy redemption activity. In addition, the Fund may invest in bond futures for the purpose of managing duration risk. For cash management purposes, the Fund may invest in other fixed income securities and money market instruments. The Fund also may invest in other financial instruments including corporate notes, convertible debt securities, preferred securities and derivatives thereof, as well as other investment companies, including exchange-traded funds, unit investment trusts, and closed-end funds, that provide inverse exposure to the high yield debt market. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments that in combination should provide inverse exposure to the U.S. and Canadian high yield bond markets.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]9688false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]9689false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Correlation and Compounding RiskA number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the high yield bond market experiences extreme volatility. In addition, as a result of compounding, the Funds performance is likely to be either greater than or less than the inverse performance of the high yield bond market, before accounting for fees and Fund expenses. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Credit Default Swap RiskThe Funds investments in credit default swaps may subject the Fund to greater risks than if the Fund were to invest directly in high yield bonds. When investing in credit default swaps, the Fund is exposed to the credit risk of both the counterparty to the credit default swap and the issuer of the underlying reference obligation. The Fund could realize a loss on its investment if it does not correctly evaluate the creditworthiness of the issuer of the bond or other reference obligation on which the credit default swap is based, as well as the continued creditworthiness of the counterparty. Investments in credit default swaps also are subject to liquidity risk. Credit RiskChanges in an issuers financial strength or in an issuers or debt securitys credit rating may affect a securitys value and thus have an impact on Fund performance. Currency RiskThe Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives RiskThe Funds investments in derivatives, such as bond futures, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Issuer Specific RiskThe value of a security may increase or decrease for a number of reasons which directly relate to the issuer. For example, with respect to the Fund, perceived poor management performance, financial leverage or reduced demand of the issuers goods or services may contribute to a decrease in the value of a security. A decrease in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the Fund to decrease. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative9715false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse698false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000015882Member_custom_C000043620Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseInverse High Yield Strategy Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000015882Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000043620Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Inverse High Yield Strategy Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus9716true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]9717false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)9718false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00750.0075falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees9719false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Advisor allocates investments to industries and styles according to several measures of momentum. Companies associated with industries and/or styles demonstrating positive momentum are favored while those experiencing negative momentum are disfavored. The Fund may hold both long and short positions. Equity positions are determined based on their associated industry and style momentum, risk characteristics, and liquidity. The Fund invests in equity securities, including small-, mid-, and large-capitalization securities, such as U.S. traded common stocks and American Depositary Receipts (ADRs), but also may invest in derivative instruments which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities of companies included in the different sectors or industries to which the Fund is seeking exposure. The Fund may invest in derivatives to hedge or gain leveraged exposure to a particular sector, industry or company depending on market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may enter into short sales of broad-based stock indices for hedging purposes in an effort to reduce portfolio risk or volatility. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash and other cash equivalents with maturities of one year or less to collateralize its derivative positions or for defensive purposes to seek to avoid losses during adverse market conditions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct significant trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]9847false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]9848false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Funds performance to be less than you expect.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Sector RiskBecause the Fund seeks to gain exposure to different industries and sectors in the economy, from time to time, it may invest a significant percentage of the Funds assets in issuers in a single industry or sector of the economy. To the extent the Fund has significant investment exposure to an industry or sector, such exposure may present more risks than if the Funds investments were more broadly diversified. While the Funds sector and industry exposure is expected to vary over time, the Fund anticipates that it may be subject to some or all of the risks described below. The list below is not a comprehensive list of the sectors and industries the Fund may have exposure to over time and should not be relied on as such.   Basic Materials Sector RiskTo the extent that the Funds investments are focused in issuers conducting business in the basic materials sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the basic materials sector. The prices of the securities of basic materials companies also may fluctuate widely due to the level and volatility of commodity prices, the exchange value of the U.S. dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.   Energy Sector RiskTo the extent that the Funds investments are focused in the energy sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the energy and energy commodities sectors. The prices of the securities of energy companies also may fluctuate widely due to changes in value and dividend yield, which depend largely on the price and supply of energy fuels, international political events relating to oil producing countries, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies.   Financial Services Sector RiskTo the extent that the Funds investments are focused in issuers conducting business in the financial services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of financial commitments they can make, and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. In addition, the recent deterioration of the credit markets generally has caused an adverse impact on a wide range of financial institutions and markets. Recent events in the financial sector have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and caused certain financial services companies to incur large losses.   Real Estate Sector RiskTo the extent that the Funds investments are focused in issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The general performance of the real estate industry has historically been cyclical and particularly sensitive to economic downturns. Changes in prevailing real estate values and rental income, interest rates and changing demographics may affect the value of securities of issuers in the real estate industry. Investments in real estate companies and REITs also may subject the Fund to the risks associated with the direct ownership of real estate. In addition to these risks, REITs are dependent on specialized management skills. These factors may increase the volatility of the Funds investments in REITs.   Technology Sector RiskTo the extent that the Funds investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, problems relating to bringing their products to market, very high price/earnings ratios, and high personnel turnover due to severe labor shortages for skilled technology professionals.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the security sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The Advisor allocates investments to industries and styles according to several measures of momentum. Companies associated with industries and/or styles demonstrating positive momentum are favored while those experiencing negative momentum are disfavored. The Fund may hold both long and short positions. Equity positions are determined based on their associated industry and style momentum, risk characteristics, and liquidity. The Fund invests in equity securities, including small-, mid-, and large-capitalization securities, such as U.S. traded common stocks and American Depositary Receipts (ADRs), but also may invest in derivative instruments which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities of companies included in the different sectors or industries to which the Fund is seeking exposure. The Fund may invest in derivatives to hedge or gain leveraged exposure to a particular sector, industry or company depending on market conditions. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market, which generally provides for less transparency than exchange-traded derivative instruments. The Fund also may enter into short sales of broad-based stock indices for hedging purposes in an effort to reduce portfolio risk or volatility. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash and other cash equivalents with maturities of one year or less to collateralize its derivative positions or for defensive purposes to seek to avoid losses during adverse market conditions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct significant trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Sector RiskBecause the Fund seeks to gain exposure to different industries and sectors in the economy, from time to time, it may invest a significant percentage of the Funds assets in issuers in a single industry or sector of the economy. To the extent the Fund has significant investment exposure to an industry or sector, such exposure may present more risks than if the Funds investments were more broadly diversified. While the Funds sector and industry exposure is expected to vary over time, the Fund anticipates that it may be subject to some or all of the risks described below. The list below is not a comprehensive list of the sectors and industries the Fund may have exposure to over time and should not be relied on as such. Basic Materials Sector RiskTo the extent that the Funds investments are focused in issuers conducting business in the basic materials sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the basic materials sector. The prices of the securities of basic materials companies also may fluctuate widely due to the level and volatility of commodity prices, the exchange value of the U.S. dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices. Energy Sector RiskTo the extent that the Funds investments are focused in the energy sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the energy and energy commodities sectors. The prices of the securities of energy companies also may fluctuate widely due to changes in value and dividend yield, which depend largely on the price and supply of energy fuels, international political events relating to oil producing countries, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies. Financial Services Sector RiskTo the extent that the Funds investments are focused in issuers conducting business in the financial services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of financial commitments they can make, and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. In addition, the recent deterioration of the credit markets generally has caused an adverse impact on a wide range of financial institutions and markets. Recent events in the financial sector have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and caused certain financial services companies to incur large losses. Real Estate Sector RiskTo the extent that the Funds investments are focused in issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The general performance of the real estate industry has historically been cyclical and particularly sensitive to economic downturns. Changes in prevailing real estate values and rental income, interest rates and changing demographics may affect the value of securities of issuers in the real estate industry. Investments in real estate companies and REITs also may subject the Fund to the risks associated with the direct ownership of real estate. In addition to these risks, REITs are dependent on specialized management skills. These factors may increase the volatility of the Funds investments in REITs. Technology Sector RiskTo the extent that the Funds investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, problems relating to bringing their products to market, very high price/earnings ratios, and high personnel turnover due to severe labor shortages for skilled technology professionals. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the security sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]10095false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Funds investment methodology is based on a systematic algorithm developed through extensive quantitative research that is designed to select and weight a basket of six liquid, investable factors: small cap and distressed equities, high yield (or junk) bonds and credit, merger arbitrage and an illiquidity premium. In combination, these six factors seek to target return characteristics similar to those of the universe of event driven hedge funds. Event driven hedge funds seek to profit from potential mispricings of the securities and the pricing spreads created by the risks related to a specific corporate transaction or market event. Such events can include: mergers, bankruptcies, financial or operational stress, restructurings, asset sales, recapitalizations, spin-offs, litigation, regulatory and legislative changes as well as other types of corporate events. Small cap equities, high yield bonds, and the equities of distressed companies combined with credit derivatives are a proxy for the primary instruments and exposures traded by distressed and opportunistic credit funds. A merger arbitrage index offers exposure to a liquid, diversified and broadly representative set of arbitrage positions on announced American and Western European merger and acquisition deals. The illiquidity factor seeks to represent the risk premium that may be achieved by holding illiquid securities. The factors and weights of those factors identified by the algorithm may change over time and may be long or short at any given time.   The Fund primarily seeks to obtain these exposures through swap agreements, but it also may invest in a combination of: domestic and foreign common stock; American Depositary Receipts (ADRs); credit or equity-linked instruments, primarily consisting of structured notes and exchange-traded notes (ETNs); exchange-traded funds (ETFs); other pooled investment vehicles; and other derivatives, primarily consisting of futures, options, and options on futures. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. The Funds use of derivatives and the leveraged investment exposure created by such use may be significant at times.   Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. From time to time, the Fund also may enter into short sales and invest in short positions of certain of its portfolio investments. The Fund may invest in derivatives to hedge or gain leveraged exposure to the components of a particular investable factor. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash, and other cash equivalents with maturities of one year or less to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks.   In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund also may engage in frequent and active trading or portfolio investments to achieve its investment objective. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]10096false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]10097false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility.   Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment.   Credit and Equity-Linked Derivative Investment RiskThe value of the Funds investment in these securities will rise or fall in response to changes in the underlying security or related benchmark or investment. These securities expose the Fund economically to movements in the prices of the underlying credit or equity security.   Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.   Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.   Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.   Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.   Exchange-Traded Notes (ETNs) RiskThe value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or securities markets, changes in the applicable interest rates, changes in the issuers credit rating and economic, legal, political or geographic events that affect the referenced commodity or security. The Funds decision to sell its ETN holdings also may be limited by the availability of a secondary market. If the Fund must sell some or all of its ETN holdings and the secondary market is weak, it may have to sell such holdings at a discount. ETNs also are subject to counterparty credit risk and fixed income risk.   Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes.   Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.   High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.   Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses.   Investment Technique RiskSome investment techniques of the Fund may be considered aggressive. Risks associated with the use of futures contracts, options, structured notes, and swap agreements include potentially dramatic price changes (losses) in the value of the instruments and imperfect correlations between the price of the contract and the underlying security or index. These instruments may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed.   Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return.   Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.   Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money.   Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.   OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.   Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Funds performance to be less than you expect.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the security sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling.   Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.   Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]10141false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Funds investment methodology is based on a systematic algorithm developed through extensive quantitative research that is designed to select and weight a basket of six liquid, investable factors: small cap and distressed equities, high yield (or junk) bonds and credit, merger arbitrage and an illiquidity premium. In combination, these six factors seek to target return characteristics similar to those of the universe of event driven hedge funds. Event driven hedge funds seek to profit from potential mispricings of the securities and the pricing spreads created by the risks related to a specific corporate transaction or market event. Such events can include: mergers, bankruptcies, financial or operational stress, restructurings, asset sales, recapitalizations, spin-offs, litigation, regulatory and legislative changes as well as other types of corporate events. Small cap equities, high yield bonds, and the equities of distressed companies combined with credit derivatives are a proxy for the primary instruments and exposures traded by distressed and opportunistic credit funds. A merger arbitrage index offers exposure to a liquid, diversified and broadly representative set of arbitrage positions on announced American and Western European merger and acquisition deals. The illiquidity factor seeks to represent the risk premium that may be achieved by holding illiquid securities. The factors and weights of those factors identified by the algorithm may change over time and may be long or short at any given time. The Fund primarily seeks to obtain these exposures through swap agreements, but it also may invest in a combination of: domestic and foreign common stock; American Depositary Receipts (ADRs); credit or equity-linked instruments, primarily consisting of structured notes and exchange-traded notes (ETNs); exchange-traded funds (ETFs); other pooled investment vehicles; and other derivatives, primarily consisting of futures, options, and options on futures. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. The Funds use of derivatives and the leveraged investment exposure created by such use may be significant at times. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. From time to time, the Fund also may enter into short sales and invest in short positions of certain of its portfolio investments. The Fund may invest in derivatives to hedge or gain leveraged exposure to the components of a particular investable factor. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash, and other cash equivalents with maturities of one year or less to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund also may engage in frequent and active trading or portfolio investments to achieve its investment objective. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]10142false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]10143false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Credit and Equity-Linked Derivative Investment RiskThe value of the Funds investment in these securities will rise or fall in response to changes in the underlying security or related benchmark or investment. These securities expose the Fund economically to movements in the prices of the underlying credit or equity security. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Exchange-Traded Notes (ETNs) RiskThe value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or securities markets, changes in the applicable interest rates, changes in the issuers credit rating and economic, legal, political or geographic events that affect the referenced commodity or security. The Funds decision to sell its ETN holdings also may be limited by the availability of a secondary market. If the Fund must sell some or all of its ETN holdings and the secondary market is weak, it may have to sell such holdings at a discount. ETNs also are subject to counterparty credit risk and fixed income risk. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Investment Technique RiskSome investment techniques of the Fund may be considered aggressive. Risks associated with the use of futures contracts, options, structured notes, and swap agreements include potentially dramatic price changes (losses) in the value of the instruments and imperfect correlations between the price of the contract and the underlying security or index. These instruments may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the security sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false0Performance Table Narrative10169false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse730false USDtruefalse$AsOf2013-07-29_custom_ProspectusOneMember_custom_S000029171Member_custom_C000089670Memberhttp://www.sec.gov/CIK0000899148duration2013-07-29T00:00:002013-07-29T00:00:00falsefalseEvent Driven and Distressed Strategies Funddei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_S000029171Memberdei_LegalEntityAxisexplicitMemberfalsefalseH-Classrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_C000089670Memberrr_ProspectusShareClassAxisexplicitMemberfalsefalseAdvisor Class, Investor Class and H-Class Shares Prospectusdei_DocumentInformationDocumentAxisxbrldihttp://xbrl.org/2006/xbrldick0000899148_ProspectusOneMemberdei_DocumentInformationDocumentAxisexplicitMemberRatioStandardhttp://www.xbrl.org/2003/instancepurexbrli0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse0Event Driven and Distressed Strategies Fund | H-Class | Advisor Class, Investor Class and H-Class Shares Prospectus10170true 1rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse0[RiskReturnAbstract]10171false 2rr_ShareholderFeeOtherrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truefalsetrue00USD$falsefalsefalserr:NonNegativeMonetaryTypemonetaryOther ExpensesReference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection table -Paragraph 1 -Subparagraph 10 false2SHAREHOLDER FEES (fees paid directly from your investment)10172false 2rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00900.0090falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false0Management Fees10173false 2rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00250.0025falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

The Fund operates in compliance with U.S. Securities and Exchange Commission (the SEC) rules, including Rule 2a-7, which impose certain liquidity, maturity and diversification requirements on all registered money market funds. All securities purchased by the Fund must have remaining maturities of 397 days or less, and must be found by the Advisor to represent minimal credit risk and be of eligible quality.   Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in government securities as defined by Section 2(a)(16) of the 1940 Act (and derivatives thereof). Section 2(a)(16) of the 1940 Act defines government security to mean any security issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States; or any certificate of deposit for any of the foregoing.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   Credit RiskThe Fund could lose money if the issuer or guarantor of a debt instrument in which it invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations.   Income RiskIncome Risk involves the potential for decline in the Funds yield (the rate of dividends the Fund pays) in the event of declining interest rates.   Interest Rate RiskThe market value of fixed income investments and related financial instruments will change in response to interest rate changes. During periods of falling interest rates, the values of fixed income securities generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline.   Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the repurchase agreement counterparty and underlying collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.   Stable Price Per Share RiskThe Funds assets are valued using the amortized cost method, which enables the Fund to maintain a stable price of $1.00 per share. Although the Fund is managed to maintain a stable price per share of $1.00, there is no guarantee that the price will be constantly maintained, and it is possible to lose money.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]10384false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]10385false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Credit RiskThe Fund could lose money if the issuer or guarantor of a debt instrument in which it invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations. Income RiskIncome Risk involves the potential for decline in the Funds yield (the rate of dividends the Fund pays) in the event of declining interest rates. Interest Rate RiskThe market value of fixed income investments and related financial instruments will change in response to interest rate changes. During periods of falling interest rates, the values of fixed income securities generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the repurchase agreement counterparty and underlying collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Stable Price Per Share RiskThe Funds assets are valued using the amortized cost method, which enables the Fund to maintain a stable price of $1.00 per share. Although the Fund is managed to maintain a stable price per share of $1.00, there is no guarantee that the price will be constantly maintained, and it is possible to lose money.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).  The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10459false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00 The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark on a daily basis.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy [Heading]10470false 2rr_StrategyNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund invests principally in securities of companies included in the underlying index and in derivative instruments which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its investment objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to one or more foreign countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The MSCI EAFE Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the U.S. and Canada. As of [date] the MSCI EAFE Index consisted of the following 21 developed market country indices: [Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.] As of [date], the MSCI EAFE Index included companies with capitalizations ranging from $        billion to $        billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry, the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day move approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Times New Roman, Times, Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivative, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK  The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices to fluctuate over time. An investment in the Fund may lose money. MID-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is not actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating  greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SMALL-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).  The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10484false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark on a daily basis.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its investment objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to one or more foreign countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The MSCI EAFE Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the U.S. and Canada. As of [date] the MSCI EAFE Index consisted of the following 21 developed market country indices: [Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.] As of [date], the MSCI EAFE Index included companies with capitalizations ranging from $         billion to $         billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry, the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day move approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivative, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK  The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices to fluctuate over time. An investment in the Fund may lose money. MID-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is not actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SMALL-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10543false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The MSCI EAFE Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the U.S. and Canada. As of [date] the MSCI EAFE Index consisted of the following 21 developed market country indices: [Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.] As of [date], the MSCI EAFE Index included companies with capitalizations ranging from $        billion to $        billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Times New Roman, Times, Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. MID-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. SMALL-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that small-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10568false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The MSCI EAFE Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance, excluding the U.S. and Canada. As of [date] the MSCI EAFE Index consisted of the following 21 developed market country indices: [Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.] As of[date], the MSCI EAFE Index included companies with capitalizations ranging from $         billion to $         billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown.   Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. MID-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. SMALL-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that small-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect.   TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10627false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The MSCI Pacific Index is a free float-adjusted market capitalization index that is designed to measure equity market performance in the Pacific region. As of [date], the MSCI Pacific Index consisted of the following [5] developed market countries: [Australia, Hong Kong, Japan, New Zealand, and Singapore]. As of [date], the MSCI Pacific IndexSM included companies with capitalizations ranging from $        billion to $        billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Times New Roman, Times, Serif;

COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN THE PACIFIC REGION RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting the Pacific region, which consists of Hong Kong, Japan, Singapore, Australia, and New Zealand. In addition, the Funds performance is expected to be closely tied to social, political, and economic conditions within Pacific and to be more volatile than the performance of geographically diversified funds. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. MID-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. SMALL-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that small-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The MSCI Pacific Index is a free float-adjusted market capitalization index that is designed to measure equity market performance in the Pacific region. As of [date], the MSCI Pacific Index consisted of the following [5] developed market countries: [Australia, Hong Kong, Japan, New Zealand, and Singapore]. As of [date], the MSCI Pacific IndexSM included companies with capitalizations ranging from $         billion to $         billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]10667false 2rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]10668false 2rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN THE PACIFIC REGION RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting the Pacific region, which consists of Hong Kong, Japan, Singapore, Australia, and New Zealand. In addition, the Funds performance is expected to be closely tied to social, political, and economic conditions within Pacific and to be more volatile than the performance of geographically diversified funds. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK  The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. MID-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. SMALL-CAPITALIZATION SECURITIES RISK  The Fund is subject to the risk that small-capitalization stocks may outperform other segments of the equity market or the equity market as a whole. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).  The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10711false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its investment objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to one or more foreign countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P Latin America 40 Index represents the major economic sectors of Mexican and South American equity markets. It includes highly liquid securities from Mexico, Brazil, Argentina and Chile. The Index serves to cover the large-cap liquid constituents of each key country in Latin America. It is also the Latin America component of S&P Global 1200. As of [date], the S&P Latin America 40 Index included companies with capitalizations ranging from $        billion to $        billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry, the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day move approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Times New Roman, Times, Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivative, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EMERGING MARKETS RISK  The Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN LATIN AMERICA RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting Latin America. While the Funds underlying index is designed to include only blue chip stocks from the four countries markets, each countrys economy is considered to be an emerging market economy. High interest, inflation, and unemployment rates generally characterize each economy. Currency fluctuations or devaluations in any country can have a significant effect on investments in the Fund. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK  The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices to fluctuate over time. An investment in the Fund may lose money. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is not actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

The effect of leverage on the Fund will generally cause the Funds performance to not match the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).  The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement [Text Block]10736false 2rr_ObjectivePrimaryTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its investment objective by increasing the Funds exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to one or more foreign countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P Latin America 40 Index represents the major economic sectors of Mexican and South American equity markets. It includes highly liquid securities from Mexico, Brazil, Argentina and Chile. The Index serves to cover the large-cap liquid constituents of each key country in Latin America. It is also the Latin America component of S&P Global 1200. As of [date], the S&P Latin America 40 Index included companies with capitalizations ranging from $         billion to $         billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry, the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day move approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivative, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EMERGING MARKETS RISK  The Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN LATIN AMERICA RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting Latin America. While the Funds underlying index is designed to include only blue chip stocks from the four countries markets, each countrys economy is considered to be an emerging market economy. High interest, inflation, and unemployment rates generally characterize each economy. Currency fluctuations or devaluations in any country can have a significant effect on investments in the Fund. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK  The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices to fluctuate over time. An investment in the Fund may lose money. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is not actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.   The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below).   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The S&P Latin America 40 Index represents the major economic sectors of Mexican and South American equity markets. It includes highly liquid securities from Mexico, Brazil, Argentina and Chile. The Index serves to cover the large-cap liquid constituents of each key country in Latin America. It is also the Latin America component of S&P Global 1200. As of [date], the S&P Latin America 40 Index included companies with capitalizations ranging from $        billion to $        billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:   ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EMERGING MARKETS RISK  The Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN LATIN AMERICA RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting Latin America. While the Funds underlying index is designed to include only blue chip stocks from the four countries markets, each countrys economy is considered to be an emerging market economy. High interest, inflation, and unemployment rates generally characterize each economy. Currency fluctuations or devaluations in any country can have a significant effect on investments in the Fund. INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The Dow Jones Stoxx 50 IndexSM is a capitalization-weighted index composed of 50 European blue chip stocks. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. As of [date], the Dow Jones Stoxx 50 IndexSM included companies with a capitalization range of $         billion to $         billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EMERGING MARKETS RISK The Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. EQUITY RISK The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN LATIN AMERICA RISK Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting Latin America. While the Funds underlying index is designed to include only blue chip stocks from the four countries markets, each countrys economy is considered to be an emerging market economy. High interest, inflation, and unemployment rates generally characterize each economy. Currency fluctuations or devaluations in any country can have a significant effect on investments in the Fund. INVESTMENT IN INVESTMENT COMPANIES RISK Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. NON-DIVERSIFICATION RISK The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. STATUS AS A REGULATED INVESTMENT COMPANY RISK The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The Dow Jones Stoxx 50 IndexSM is a capitalization-weighted index composed of 50 European blue chip stocks. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. As of [date], the Dow Jones Stoxx 50 IndexSM included companies with a capitalization range of $    billion to $    billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index.   <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EMERGING MARKETS RISK  The Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN EUROPE RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting Europe. In addition, countries in Europe may be significantly affected by the tight fiscal and monetary controls of the European Economic and Monetary Union (EMU). INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund.

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Equity index swaps, short sales, and futures and options contracts enable the Fund to pursue its objective without selling short each of the securities included in the underlying index. The Fund may also invest in exchange-traded funds (ETFs) that provide exposure to emerging market countries and in American Depositary Receipts (ADRs) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The Dow Jones Stoxx 50 IndexSM is a capitalization-weighted index composed of 50 European blue chip stocks. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. As of [date], the Dow Jones Stoxx 50 IndexSM included companies with a capitalization range of $         billion to $         billion. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. . In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. To the extent the underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: ACTIVE TRADING RISK  Active trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. CORRELATION AND COMPOUNDING RISK  A number of factors may affect the Funds ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Funds performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Funds investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Funds benchmark. This effect becomes more pronounced as volatility increases. Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors volatility and index performance on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Funds performance would be lower than shown. Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than twice the performance of the underlying index. <table cellspacing="0" cellpadding="0" style="font: 8pt Calibri, Helvetica, Sans-Serif;

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. COUNTERPARTY CREDIT RISK  The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. CURRENCY RISK  The Funds indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. DEPOSITARY RECEIPT RISK  The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. DERIVATIVES RISK  The Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. EARLY CLOSING RISK  The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. EMERGING MARKETS RISK  The Funds investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor. EQUITY RISK  The Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. FOREIGN ISSUER EXPOSURE RISK  The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. GEOGRAPHIC CONCENTRATION IN EUROPE RISK  Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the net asset value of the Fund could decline more dramatically as a result of adverse events affecting Europe. In addition, countries in Europe may be significantly affected by the tight fiscal and monetary controls of the European Economic and Monetary Union (EMU). INVESTMENT IN INVESTMENT COMPANIES RISK  Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. LEVERAGING RISK The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Funds investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Funds investment strategy involves consistently applied leverage, the value of the Funds shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error. LIQUIDITY RISK  In certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. MARKET RISK  The Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. NON-DIVERSIFICATION RISK  The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC TRADING RISK  Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. PASSIVE INVESTMENT RISK  The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed. PORTFOLIO TURNOVER RISK  The Funds strategy may frequently involve buying and selling portfolio securities to rebalance the Funds exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Funds performance to be less than you expect. SHORT SALES RISK  Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. STATUS AS A REGULATED INVESTMENT COMPANY RISK  The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future. TRACKING ERROR RISK  The Advisor may not be able to cause the Funds performance to correlate to that of the Funds benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Funds investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Funds performance to be less than you expect. TRADING HALT RISK  If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.
