The Nova Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. 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 Fund’s performance to not match the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from 1.5x of the return of the Fund’s 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 Fund’s 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 Fund’s 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.

Objective [Heading]

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is 150% of the performance of the S&P 500^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 403% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Investments in derivative instruments, such as futures, options and swap agreements, have the economic effect of creating financial leverage in the Fund’s portfolio because such investments may give rise to losses that exceed the amount the Fund has invested in those instruments. Financial leverage will magnify, sometimes significantly, the Fund’s exposure to any increase or decrease in prices associated with a particular reference asset resulting in increased volatility in the value of the Fund’s portfolio. The value of the Fund’s portfolio is likely to experience greater volatility over short-term periods. While such financial leverage has the potential to produce greater gains, it also may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at a loss to comply with limits on leverage and asset segregation requirements imposed by the Investment Company Act of 1940 or to meet redemption requests.

The S&P 500^® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poor’s Corporation (“S&P”) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $3.3 billion to $722.7 billion as of June 30, 2015. To the extent the Fund’s 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. 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 certain circumstances the Fund may invest a substantial portion of its assets in other short-term fixed-income investment companies advised by the Advisor, or an affiliate of the Advisor, for liquidity management purposes, including in order to increase yield on liquid investments used to collateralize derivatives positions. Investments in these investment companies will significantly increase the portfolio’s exposure to certain other asset categories, including: (i) a broad range of high yield, high risk debt securities rated below the top four long-term rating categories by a nationally recognized statistical rating organization or, if unrated, determined by the Advisor, to be of comparable quality (also known as “junk bonds”); (ii) securities issued by the U.S. government or its agencies and instrumentalities; (iii) collateralized loan obligations (“CLOs”), other asset-backed securities (including mortgage-backed securities) and similarly structured debt investments; and (iv) other short-term fixed income securities. Such investments will expose the Fund to the risks of these asset categories and increases or decreases in the value of these investments may cause the Fund to deviate from its investment objective.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

ACTIVE TRADING RISK—The Fund may be used as a tool for certain investors that employ trading strategies involving frequent trading. Such trading strategies may lead to increased portfolio turnover in the Fund, higher transaction costs, and the possibility of increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them) and/or long-term capital gains. Large movements of assets into and out of the Fund due to active or frequent trading also may adversely affect the Fund's ability to achieve its investment objective.

ASSET-BACKED AND MORTGAGE-BACKED SECURITIES RISK—Through its investments in other investment companies, the Fund may have exposure to asset-backed securities, including mortgage-backed securities and structured finance investments. Investors in these securities generally receive payments that are part interest and part return of principal. These payments may vary based on the rate at which the underlying borrowers pay off their loans. Some asset-backed securities, including mortgage-backed securities, may have structures that make their reaction to interest rates and other factors difficult to predict, making their prices very volatile and they are subject to liquidity risk.

CLO RISK—Through its investments in other investment companies, the Fund may have exposure to CLOs. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. The cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults, as well as aversion to CLO securities as a class. The risks of an investment in a CLO depend largely on the type of the collateral securities and the class of the CLO in which the Fund invests.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund does not attempt to, and should not be expected to, provide returns which are a multiple of the returns of the underlying index for periods other than a single day. 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 Fund’s 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 Fund’s 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 Fund’s 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 table below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The table shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the table 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, including the cost of leverage, were included, the Fund’s 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.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2015 is 12.00%. The underlying index’s highest one-year volatility rate during the five year period is 18.18%. The underlying index’s annualized performance for the five year period ended June 30, 2015 is 17.34%.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future. The table is intended to underscore that the Fund is designed as a short-term trading vehicle for investors who intend to actively monitor and manage their portfolios.

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 Fund’s use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, the Fund is exposed to the risk that the counterparty may be unwilling or unable to make timely payments to meet its contractual obligations or may fail to return holdings that are subject to the agreement with the counterparty. If the counterparty becomes bankrupt or defaults on its payment obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive. If this occurs, the value of your shares in the Fund will decrease.

CREDIT RISK—The Fund could lose money if the issuer or guarantor of a debt instrument in which it invests or a counterparty to a derivatives transaction or other transaction becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations. The issuer of a debt instrument, such as a bond, could also suffer a decrease in quality rating, which may affect the volatility of the price and liquidity of the bond.

DERIVATIVES RISK—The Fund’s investments in derivatives may pose risks in addition to and greater than those associated with investing directly in securities or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Advisor is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. Certain risks are specific to the derivatives in which the Fund invests.

SWAP AGREEMENTS RISK—Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, in some instances, must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free.

FUTURES CONTRACTS RISK—Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying securities. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Advisor, thus limiting the ability to implement the Fund’s strategies. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s NAV. Futures are also subject to leverage risks and to liquidity risk.

OPTIONS RISK—Options or options on futures contracts give the holder of the option the right to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. They are subject to correlation risk because there may be an imperfect correlation between the options and the securities markets that cause a given transaction to fail to achieve its objectives. The successful use of options depends on the Advisor’s ability to correctly predict future price fluctuations and the degree of correlation between the options and securities markets. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Advisor, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity 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 Fund’s 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 Fund’s 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.

HIGH YIELD AND UNRATED SECURITIES RISK—The Fund’s exposure to higher yielding, below investment grade and unrated high risk debt securities (commonly known as “junk bonds”) may present additional risk because these securities may be less liquid and present greater credit risk than investment grade bonds. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions. This exposure may be obtained through investments in other investment companies.

INTEREST RATE RISK—The 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. Accordingly, the potential for the value of a floating rate security to increase/decrease in response to interest rate declines/increases is limited. Fixed income securities with longer durations are subject to greater volatility than those with shorter durations. Thus, if interest rates rise sharply, the value of the Fund’s fixed income investments and share price could decline. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.

INVESTMENT IN INVESTMENT VEHICLES RISK—Investing in other investment vehicles, including, exchange-traded funds, closed-end funds, affiliated short-term fixed-income funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment vehicles’ expenses. Consequently, an investment in the Fund entails more direct and indirect expenses than a direct investment in the underlying investment vehicles.

INVESTMENTS IN LOANS RISK—Investments in loans involve special types of risks, including credit risk, interest rate risk, counterparty risk and prepayment risk. Loans may offer a fixed or floating interest rate. Loans are often generally below investment grade and may be unrated. Loans may be difficult to value and some can be subject to liquidity risk.

LARGE-CAPITALIZATION SECURITIES RISK—The 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 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 Fund’s 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 Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s 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 a particular security or derivative instrument 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 RISK—The market value of the securities and derivatives held by the Fund may fluctuate resulting from factors affecting the individual company or other factors such as changing economic, political or financial market conditions. Moreover, changing economic, political or financial market conditions in one country or geographic region could adversely impact the market value of the securities held by the Fund in a different country or geographic region.

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 derivatives 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—Daily rebalancing of the Fund's holdings pursuant to its daily investment objective may lead to a greater number of portfolio transactions in the Fund than experienced by other mutual funds. Such frequent and active trading may lead to significantly higher transaction costs because of increased broker commissions associated with such transactions.

PREPAYMENT RISK—The Fund’s investments in or exposure to fixed income investments subjects the Fund to prepayment risk. Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities, and may offer a greater potential for income loss when interest rates rise.

REPURCHASE AGREEMENT RISK—The Fund’s 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 RISK—The 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s 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 Fund’s ability to use leverage and may prevent the Fund from achieving its investment objective.

U.S. GOVERNMENT SECURITIES RISK—U.S. government securities may or may not be backed by the full faith and credit of the U.S. government. The value of U.S. government securities will fluctuate and such securities are subject to the risks associated with fixed-income and debt securities, particularly interest rate and credit risk.

The S&P 500^® Fund (the “Fund”) seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the S&P 500^® Index (the “underlying index”).

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 256% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The S&P 500^® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poor’s Corporation (“S&P”) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $3.3 billion to $722.7 billion as of June 30, 2015. To the extent the Fund’s 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. 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

LARGE-CAPITALIZATION SECURITIES RISK—The 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

INVERSE S&P 500® STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse S&P 500^® Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. 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 day’s compounded returns over the period, which will very likely differ from the inverse return of the Fund’s 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 Fund’s 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 Fund’s 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.

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the inverse (opposite) of the performance of the S&P 500^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 103% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Unlike a traditional index fund, the Fund’s investment objective is to perform exactly opposite the underlying index, and the Fund generally will not own the securities included in the underlying index. 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. While the Fund may write (sell) and purchase swaps, it expects primarily to write swaps. The Fund’s 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 Fund’s derivatives 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.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s 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.

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.

60%	-60%	-38%	-41%	-51%	-65%	-78%

LARGE-CAPITALIZATION SECURITIES RISK—The 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.

PASSIVE INVESTMENT RISK—The 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.

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 Fund’s ability to engage in short selling.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

MONTHLY REBALANCE NASDAQ-100® 2X STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Monthly Rebalance NASDAQ-100^® 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks calendar month leveraged investment results. 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 Fund’s performance to not match the performance of the Fund’s benchmark (as described below) over a period of time longer than a full calendar month. This means that the return of the Fund for a period longer than a full calendar month will be the result of each calendar month's compounded return over the period, which will very likely differ from twice the return of the Fund’s 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 Fund’s 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 different than a full calendar month (whether for a period shorter than or longer than a full calendar month) will not be the product of the return of the Fund’s stated investment goal (i.e., 2x) and the cumulative performance of the underlying index (as defined below) for the full calendar month.

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 monthly 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.

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a calendar month basis. The Fund’s current benchmark is 200% of the performance of the NASDAQ-100 Index^® (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time different than a full calendar month.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 84% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund employs as its investment strategy a program of investing in the common stock of companies included in the underlying index or common stock with the same characteristics as those included in the Fund's benchmark and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or providing exposure in the same proportion that those securities are represented in the Fund's benchmark. The Fund may also purchase options contracts designed to protect the value of the Fund's portfolio or particular instruments held by the Fund in the event of an extreme intra-month movement in the value of the underlying index. The Fund is not obligated to engage in such protective investment measures nor is there any guarantee that such measures will be successful in protecting the value of the Fund. Such protective measures may also adversely affect the Fund's ability to realize extreme gains in the value of the Fund's benchmark. The Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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 Fund's benchmark. 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 securities and financial instruments with economic characteristics that should perform similarly to the securities of companies in the Fund's benchmark.

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 $8.4 billion to $722.7 billion as of June 30, 2015. To the extent the Fund’s 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. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. Depending on the effect on the Fund's portfolio of the underlying index's movements during any calendar month it may be necessary for the Advisor to rebalance the Fund's portfolio on the last trading day of each calendar month. Generally, the Fund's portfolio would be rebalanced at the end of a given month to increase the portfolio's exposure in response to that calendar month's gains or to reduce the portfolio's exposure in response to that calendar month's losses. 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.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its benchmark on a calendar month basis, including costs associated with the use of leveraged investment techniques, 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 Fund does not attempt to, and should not be expected to, provide returns which are a multiple of the returns of the underlying index for periods other than a full calendar month. The risk of the Fund not achieving its calendar month investment objective will be more acute when the underlying index has an extreme intra-month movement approaching -50%. The Fund rebalances its portfolio on a calendar month basis, increasing exposure in response to that calendar month's gains and vice versa. This means that for a period longer than a calendar month, the pursuit of the Fund's investment objective may result in calendar month leveraged compounding. As a result, the Fund’s performance for periods different than a full calendar month is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for Fund fees and expenses.

Fund performance for periods different than a full calendar month 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 table below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The table shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the table 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, including the cost of leverage, were included, the Fund’s 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.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2015 is 13.85%. The underlying index’s highest one-year volatility rate during the five year period is 19.49%. The underlying index’s annualized performance for the five year period ended June 30, 2015 is 21.81%.

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 Fund’s portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Fund’s 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.

FUTURES CONTRACTS RISK—Futures contracts are typically exchange traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying securities. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Advisor, thus limiting the ability to implement the Fund’s strategies. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s NAV. Futures are also subject to leverage risks and to liquidity risk.

FOREIGN ISSUER EXPOSURE RISK—The Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers, such as ADRs. The Fund’s exposure to foreign issuers and investments in foreign securities, if any, are subject to additional risks in comparison to U.S. securities and U.S. issuers, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

INDUSTRY AND TECHNOLOGY SECTOR CONCENTRATION RISK—The 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 Fund’s 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.

INTRA-CALENDAR MONTH INVESTMENT RISK—The Fund seeks calendar month leveraged investment results which should not be equated with seeking a leveraged goal for a period different than a calendar month. An investor who purchases shares on a day other than the last business day of a calendar month will likely have more, or less, than 200% leveraged investment exposure to the underlying index, depending upon the movement of the underlying index from the end of the prior calendar month until the point of purchase. If the underlying index moves in a direction favorable to the Fund, the investor will receive less than 200% exposure to the underlying index. Conversely, if the underlying index moves in a direction adverse to the Fund, the investor will receive greater than 200% exposure to the underlying index. Only on the last trading day of a calendar month, could an investor receive 200% exposure to the underlying index.

INVESTMENT IN INVESTMENT VEHICLES RISK—Investing in other investment vehicles, including, exchange-traded funds, closed-end funds, affiliated short-term fixed-income funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease. Moreover, the Fund and will incur its pro rata share of the expenses of the underlying investment vehicles’ expenses. Consequently, an investment in the Fund entails more direct and indirect expenses than a direct investment in the underlying investment vehicles.

LARGE-CAPITALIZATION SECURITIES RISK—The 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 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 Fund’s 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 Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Further, purchasing shares intra-calendar month may result in greater than 200% exposure to the performance of the underlying index if the underlying index declines between the end of the last calendar month and the time the investor purchased Fund shares. Leverage also will have the effect of magnifying tracking error.

PASSIVE INVESTMENT RISK—The Fund is not actively managed and except in response to extreme intra-month movements in the Fund's underlying index, 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 Fund’s strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

TEMPORARY DEFENSIVE INVESTMENT RISK—The Advisor generally 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a calendar month or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

INVERSE NASDAQ-100® STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse NASDAQ-100^® Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the inverse (opposite) of the performance of the NASDAQ-100 Index^® (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

Expense [Heading]

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 149% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Unlike a traditional index fund, the Fund’s investment objective is to perform exactly opposite the underlying index, and the Fund generally will not own the securities included in the underlying index. 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. While the Fund may write (sell) and purchase swaps, it expects primarily to write swaps. The Fund’s 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 Fund’s derivatives 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s 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.

60%	-60%	-38%	-41%	-51%	-65%	-78%

LARGE-CAPITALIZATION SECURITIES RISK—The 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

MID-CAP 1.5X STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Mid-Cap 1.5x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. 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 Fund’s performance to not correlate to the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from 1.5x of the return of the Fund’s 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 Fund’s 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 Fund’s stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The 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 Fund’s current benchmark is 150% of the performance of the S&P MidCap 400^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

These costs, which are not reflected in Total 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 598% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The 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. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Fund's benchmark. The Advisor attempts to consistently apply leverage to increase the Fund’s exposure to 150% of the underlying index. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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 Fund's benchmark.

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 $608.4 million to $11.7 billion as of June 30, 2015. To the extent the Fund’s 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. 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.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2015 is 14.56%. The underlying index’s highest one-year volatility rate during the five year period is 22.82%. The underlying index’s annualized performance for the five year period ended June 30, 2015 is 17.83%.

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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to correlate to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

Supplement [Text Block]

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse Mid-Cap Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the inverse (opposite) of the performance of the S&P MidCap 400^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 38% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The S&P MidCap 400^® Index is a modified capitalization-weighted index composed of 400 mid-cap stocks chosen by Standard & Poor's Corporation ("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 $608.4 million to $11.7 billion as of June 30, 2015. To the extent the Fund’s 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. 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s 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.

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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The 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. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Fund's benchmark. The Advisor attempts to consistently apply leverage to increase the Fund’s exposure to 150% of the underlying index. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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 Fund's benchmark.

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 $64.4 million to $4.7 billion as of June 30, 2015. 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 Fund’s 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. 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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 947% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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 $64.4 million to $4.7 billion as of June 30, 2015. 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 Fund’s 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. 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.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

Supplement [Text Block]

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse Russell 2000^® Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.

Objective [Heading]

INVESTMENT OBJECTIVE

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the inverse (opposite) of the performance of the Russell 2000^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

These costs, which are not reflected in Total 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 189% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s 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.

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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

The S&P 500^® Pure Growth Fund (the “Fund”) seeks to provide investment results that match, before fees and expenses, the performance of a benchmark for large-cap growth securities on a daily basis. The Fund’s current benchmark is the S&P 500 Pure Growth Index (the “underlying index”).

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 274% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy Narrative [Text Block]

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, 2015, the S&P 500 Pure Growth Index included companies with capitalizations ranging from $5.7 billion to $722.7 billion. To the extent the Fund’s 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 derivatives 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

GROWTH STOCKS RISK—Growth 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 RISK—The 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

The S&P MidCap 400^® Pure Value Fund (the “Fund”) seeks to provide investment results that match, before fees and expenses, the performance of a benchmark for mid-cap value securities on a daily basis. The Fund’s current benchmark is the S&P MidCap 400 Pure Value Index (the “underlying index”).

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 638% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

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, 2015, the S&P MidCap 400 Pure Value Index included companies with capitalizations ranging from $608.4 million to $8.5 billion. To the extent the Fund’s 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 derivatives 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

VALUE STOCKS RISK—Value 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

VALUE STOCKS RISK—Value 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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 583% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Banking Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Investments in derivative instruments, such as futures and options, have the economic effect of creating financial leverage in the Fund’s portfolio because such investments may give rise to losses that exceed the amount the Fund has invested in those instruments. Financial leverage will magnify, sometimes significantly, the Fund’s exposure to any increase or decrease in prices associated with a particular reference asset resulting in increased volatility in the value of the Fund’s portfolio. The value of the Fund’s portfolio is likely to experience greater volatility over short-term periods. While such financial leverage has the potential to produce greater gains, it also may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at a loss to comply with limits on leverage and asset segregation requirements imposed by the Investment Company Act of 1940 or to meet redemption requests.

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.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

BANKING SECTOR RISK—To the extent that the Fund’s 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.

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.

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.

The Biotechnology Fund (the “Fund”) seeks to provide capital appreciation by investing in companies that are involved in the biotechnology industry, including companies involved in research and development, genetic or other biological engineering, and in the design, manufacture, or sale of related biotechnology products or services (“Biotechnology Companies”).

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 107% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Biotechnology Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

BIOTECHNOLOGY SECTOR RISK—To the extent that the Fund’s 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.

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.

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.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following bar chart shows the performance of the Investor shares of the Fund from year to year. 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 Advisor shares and Investor shares of the Fund as an average over different periods of time in comparison to the performance of a broad-based market index. The figures in the bar chart and tables assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling Guggenheim Investments Client Services at 800.820.0888.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 562% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Electronics Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

ELECTRONICS SECTOR RISK—To the extent that the Fund’s 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.

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.

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.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following bar chart shows the performance of the Investor shares of the Fund from year to year. 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 Advisor shares and Investor shares of the Fund as an average over different periods of time in comparison to the performance of a broad-based market index. The figures in the bar chart and tables assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling Guggenheim Investments Client Services at 800.820.0888.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 494% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Energy Services Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

ENERGY SERVICES SECTOR RISK—To the extent that the Fund’s 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.

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.

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.

The Fund may 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.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 371% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Precious Metals Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

As 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 the principal risks described below.

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.

PRECIOUS METALS SECTOR RISK—To the extent that the Fund’s 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 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.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 280% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Technology Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

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.

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.

TECHNOLOGY SECTOR RISK—To the extent that the Fund’s 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.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

The following bar chart shows the performance of the Investor shares of the Fund from year to year. 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 Advisor shares and Investor shares of the Fund as an average over different periods of time in comparison to the performance of a broad-based market index. The figures in the bar chart and tables assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling Guggenheim Investments Client Services at 800.820.0888.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 247% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Transportation Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

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.

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.

TRANSPORTATION SECTOR RISK—To the extent that the Fund’s 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.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following bar chart shows the performance of the Investor shares of the Fund from year to year. 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 Advisor shares and Investor shares of the Fund as an average over different periods of time in comparison to the performance of a broad-based market index. The figures in the bar chart and tables assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling Guggenheim Investments Client Services at 800.820.0888.

EUROPE 1.25X STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Europe 1.25x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks leveraged investment results. 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 Fund’s performance to not correlate to the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from 1.25x of the return of the Fund’s 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 Fund’s 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 Fund’s 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.

Objective [Heading]

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 608% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The 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 (including currency futures), and options on securities, futures contracts, and stock indices. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Fund's benchmark. The Advisor attempts to consistently apply leverage to increase the Fund’s exposure to 125% of the underlying index. The Fund also has 125% exposure to the foreign currencies in which the securities included in the underlying index are denominated. If the U.S. dollar rises in value against a foreign currency, a security denominated in that currency will be worth less in U.S. dollars and if the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency will be worth more in U.S. dollars. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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 Fund's benchmark. 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 Fund's benchmark.

The STOXX Europe 50^® Index is a capitalization-weighted index composed of 50 European blue chip stocks consisting of capitalizations ranging from $13.2 billion to $192.5 billion as of June 30, 2015. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. The Fund's investment in instruments denominated in foreign currencies exposes the Fund to the risk of fluctuations in the value of such currency in comparison to the U.S. dollar. The Fund generally does not intend to hedge such foreign currency exposure. To the extent the Fund’s 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. 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.

Risk [Heading]

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for fees and Fund expenses.

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.

50%	63%	65%	64%	60%	53%	41%
60%	75%	80%	78%	73%	65%	54%

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2015 is 22.56%. The underlying index’s highest one-year volatility rate during the five year period is 31.79%. The underlying index’s annualized performance for the five year period ended June 30, 2015 is 7.17%.

CURRENCY RISK—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. 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 Fund’s performance.

FOREIGN ISSUER EXPOSURE RISK—The Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. The Fund’s investments in foreign securities and foreign issuers are subject to additional risks in comparison to U.S. securities and U.S. issuers, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

GEOGRAPHIC CONCENTRATION IN EUROPE RISK—Because a significant portion of the Fund’s 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 RISK—The 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.

The Japan 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks leveraged investment results. 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 Fund’s performance to not correlate to the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from twice the return of the Fund’s 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 Fund’s 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 Fund’s 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.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The 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 (including currency futures), and options on securities, futures contracts, and stock indices. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Fund's benchmark. The Advisor attempts to consistently apply leverage to increase the Fund's exposure to 200% of the underlying index. The Fund also has 200% exposure to the Japanese yen. If the U.S. dollar rises in value against the Japanese yen, a security denominated in Japanese yen will be worth less in U.S. dollars, and if the U.S. dollar decreases in value against the Japanese yen, a security denominated in Japanese yen will be worth more in U.S. dollars. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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 Fund's benchmark. 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 Fund's benchmark.

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 Japan’s industrial structure. As of June 30, 2015, the Nikkei 225 Stock Average included companies with small, medium and large capitalizations ranging from $273.4 million to $211 billion. The Fund's investment in instruments denominated in foreign currencies exposes the Fund to the risk of fluctuations in the value of such currency in comparison to the U.S. dollar. The Fund generally does not intend to hedge such foreign currency exposure. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry.

PRINCIPAL RISKS

Risk Narrative [Text Block]

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for fees and Fund expenses.

60%	120%	154%	140%	100%	44%	-10%

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2015 is 13.29%. The underlying index’s highest one-year volatility rate during the five year period is 17.49%. The underlying index’s annualized performance for the five year period ended June 30, 2015 is 11.37%.

CURRENCY RISK—The Fund’s 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.

FOREIGN ISSUER EXPOSURE RISK—The Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. The Fund’s investments in foreign securities and foreign issuers are subject to additional risks in comparison to U.S. securities and U.S. issuers, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

GEOGRAPHIC CONCENTRATION IN JAPAN RISK—Targeting Japan could hurt the Fund’s performance if Japan’s 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 RISK—The 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.

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.

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.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The following bar chart shows the performance of the Class H shares of the Fund from year to year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the performance of the Class H 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 Fund’s change in name and investment strategy. Prior to May 1, 2009, the Fund’s 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 Fund’s current investment strategy, which seeks to provide 200% exposure to the Nikkei 225 Stock Average, been in effect during those periods.

EMERGING MARKETS 2X STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Emerging Markets 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. 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 Fund’s performance to not correlate to the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from twice the return of the Fund’s 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 Fund’s 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 Fund’s stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

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 Fund’s current benchmark is 200% of the performance of the BNY Mellon Emerging Markets 50 ADR Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 1,085% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The 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 objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Fund's benchmark. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. The Advisor attempts to consistently apply leverage to increase the Fund's exposure to 200% of the underlying index. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivatives 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 Fund's benchmark. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s 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 Fund's benchmark.

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 $1.9 billion to $262.4 billion as of June 30, 2015. The Fund's investments may expose the Fund to the risk of fluctuations in the value of foreign currencies in comparison to the U.S. dollar. The Fund generally does not intend to hedge such foreign currency exposure. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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, the Fund’s 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 Fund’s investment objective, before accounting for fees and Fund expenses.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2015 is 19.15%. The underlying index’s highest one-year volatility rate during the five year period is 28.59%. The underlying index’s annualized performance for the five year period ended June 30, 2015 is 0.49%.

EMERGING MARKETS RISK—The Fund’s 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.

FOREIGN ISSUER EXPOSURE RISK—The Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. The Fund’s investments in foreign securities and foreign issuers are subject to additional risks in comparison to U.S. securities and U.S. issuers, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

LARGE-CAPITALIZATION SECURITIES RISK—The 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.

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.

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse Emerging Markets 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide daily leveraged investment results that correlate to the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. 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 Fund’s performance to not correlate to the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from twice the inverse return of the Fund’s 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 Fund’s 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 Fund’s 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.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund employs as its investment strategy a program of engaging in short sales of securities generally included in the underlying index and investing in leveraged derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. While the Fund may write (sell) and purchase swaps, it expects primarily to sell swaps. The Advisor attempts to consistently apply leverage to increase the Fund's exposure to -200% of the underlying index. The Fund’s 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 Fund's benchmark. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s 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 Fund’s derivatives 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 $1.9 billion to $262.4 billion as of June 30, 2015.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund does not attempt to, and should not be expected to, provide returns which are a multiple of the returns of the underlying index for periods other than a single day. 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 Fund’s 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 Fund’s investment objective, before accounting for fees and Fund expenses.

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.

STRENGTHENING DOLLAR 2X STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Strengthening Dollar 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. 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 Fund’s performance to not match the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from twice the return of the Fund’s 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 Fund’s 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 Fund’s stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Fund seeks to provide investment results that match the performance of a specific benchmark, before fees and expenses, on a daily basis. The Fund’s current benchmark is 200% of the performance of the U.S. Dollar Index^® (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 299% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund employs as its investment strategy a program of investing in derivative instruments, which primarily consist of index swaps, futures contracts, and options on securities, securities indices, and futures contracts. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. The Advisor attempts to consistently apply leverage to increase the Fund's exposure to 200% of the underlying index. 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 Fund's benchmark. The Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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. 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.

Supplement [Text Block]

IMPORTANT INFORMATION ABOUT THE FUND

The Weakening Dollar 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide leveraged investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. 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 Fund’s performance to not match the performance of the Fund’s 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 day’s compounded returns over the period, which will very likely differ from twice the inverse return of the Fund’s 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 Fund’s 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 Fund’s 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.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund employs as its investment strategy a program of engaging in short sales of securities generally included in the underlying index and investing in derivative instruments, which primarily consist of index swaps, futures contracts, and options on securities, securities indices, and futures contracts. While the Fund may write (sell) and purchase swaps, it expects primarily to write swaps. The Advisor attempts to consistently apply leverage to increase the Fund's exposure to -200% of the underlying index. The Fund’s investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index. Certain of the Fund’s derivatives investments may be traded in the over-the-counter (“OTC”) market, which generally provides for less transparency than exchange-traded derivative instruments.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund does not attempt to, and should not be expected to, provide returns which are a multiple of the returns of the underlying index for periods other than a single day. 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 Fund’s 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 Fund’s investment objective, before accounting for fees and Fund expenses.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Real Estate Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund may 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.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

INDUSTRY AND REAL ESTATE SECTOR RISK—The 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 Fund’s 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.

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.

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.

GOVERNMENT LONG BOND 1.2X STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Government Long Bond 1.2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. 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 Fund’s performance to not correspond to the performance of the Fund’s 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 day’s compounded returns over the period, which will likely differ from the return of the Fund’s 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 Fund’s 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 Fund’s stated investment goal (e.g., 1.2x) and the cumulative performance of the benchmark (as defined below).

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The 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 Fund’s 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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 1,932% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund employs as its investment strategy a program of investing in U.S. government securities and derivative instruments, which primarily consist of futures contracts, interest rate swaps, and options on securities and futures contracts. While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Futures and options contracts, and interest rate swaps, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the Fund's benchmark or to securities whose performance is highly correlated to the Fund's benchmark. The Advisor attempts to consistently apply leverage to increase the Fund's exposure to 120% of the Fund's benchmark. The Fund’s use of derivatives and the leveraged investment exposure created by such use are expected to be significant. Certain of the Fund’s derivatives 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 Fund’s U.S. government securities, or cash equivalents, will be used to collateralize its derivatives 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.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund does not attempt to, and should not be expected to, provide returns which are a multiple of the returns of the underlying index for periods other than a single day. 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 Fund’s 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 Fund’s 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 Fund’s 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 table below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The table shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the table assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses, including the cost of leverage, were included, the Fund’s 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.

60%	72%	76%	75%	71%	65%	56%

The Long Treasury Bond's annualized historical volatility rate for the five year period ended June 30, 2015 is 12.22%. The Long Treasury Bond's highest one-year volatility rate during the five year period is 16.40%. The Long Treasury Bond's annualized performance for the five year period ended June 30, 2015 is 6.25%.

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. The table is intended to underscore that the Fund is designed as a short-term trading vehicle for investors who intend to actively monitor and manage their portfolios.

LEVERAGING RISK—The 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 Fund’s 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 Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s 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.

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to correspond to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

INVERSE GOVERNMENT LONG BOND STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse Government Long Bond Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that correlate to the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. 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 day’s 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 Fund’s 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 Fund’s stated investment goal (e.g., -1x) and the cumulative performance of the benchmark.

Objective [Heading]

rr_ObjectiveHeading

INVESTMENT OBJECTIVE

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The 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 Fund’s 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.

Expense [Heading]

FEES AND EXPENSES OF THE FUND

Portfolio Turnover [Heading]

rr_PortfolioTurnoverHeading

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 2,190% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Unlike a traditional index fund, the Fund’s investment objective is to perform, on a daily basis, exactly opposite the daily price movement of the Long Treasury Bond. 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. While the Fund may write (sell) and purchase swaps, it expects primarily to write swaps. Certain of the Fund’s derivatives 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.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CORRELATION AND COMPOUNDING RISK—A number of factors may affect the Fund’s 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 Fund’s 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 Fund’s 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 table below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The table shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the table assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses, including the cost of leverage, were included, the Fund’s 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.

60%	-60%	-38%	-41%	-51%	-65%	-78%

TRACKING ERROR RISK—The Advisor may not be able to cause the Fund’s performance to correlate to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s 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 Fund’s performance to be less than you expect.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to gain exposure similar to the total return of the high yield bond market, as represented by U.S. and Canadian high yield bonds, by investing in the universe of fixed rate, non-investment grade debt through the use of credit default swaps, high yield securities, futures and other financial instruments with economic characteristics comparable to that of the high yield bond market. Generally, high yield bonds, which are also commonly referred to as “junk bonds,” are those bonds rated BB+ and lower by Standard & Poor’s Rating Service or Ba1 and lower by Moody’s 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 Fund’s 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. 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 may also 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 Fund’s 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 Fund’s derivatives investments may be traded in the over-the-counter (“OTC”) market, which generally provides for less transparency than exchange-traded derivative instruments.

Investments in derivative instruments, such as futures and swap agreements, have the economic effect of creating financial leverage in the Fund’s portfolio because such investments may give rise to losses that exceed the amount the Fund has invested in those instruments. Financial leverage will magnify, sometimes significantly, the Fund’s exposure to any increase or decrease in prices associated with a particular reference asset resulting in increased volatility in the value of the Fund’s portfolio. The value of the Fund’s portfolio is likely to experience greater volatility over short-term periods. While such financial leverage has the potential to produce greater gains, it also may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at a loss to comply with limits on leverage and asset segregation requirements imposed by the Investment Company Act of 1940 or to meet redemption requests. The Fund’s use of derivatives and the leveraged investment exposure created by the use of derivatives are expected to be significant.

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.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

CREDIT DEFAULT SWAP RISK—The Fund’s 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.

FOREIGN ISSUER EXPOSURE RISK—The Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. The Fund’s investments in foreign securities and foreign issuers are subject to additional risks in comparison to U.S. securities and U.S. issuers, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

INVESTMENT IN INVESTMENT VEHICLES RISK—Investing in other investment vehicles, including,ETFs, closed-end funds, affiliated short-term fixed-income funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment vehicles’ expenses. Consequently, an investment in the Fund entails more direct and indirect expenses than a direct investment in the underlying investment vehicles.

ISSUER SPECIFIC RISK —The 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 issuer’s 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 RISK—The Fund’s 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 Fund’s return.

INVERSE HIGH YIELD STRATEGY FUND

Supplement [Text Block]

ck000000000_SupplementTextBlock

IMPORTANT INFORMATION ABOUT THE FUND

The Inverse High Yield Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that correlate to the opposite of the performance of the high yield bond market, a result opposite of most mutual funds. 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 day’s 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 Fund’s 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 Fund’s 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.

These costs, which are not reflected in Total 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 784% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to gain exposure similar to the performance of the emerging markets bond market by investing under normal circumstances at least 80% of its net assets, plus any borrowings for investment purposes, in bonds and financial instruments that in combination have economic characteristics similar to emerging markets bonds. For purposes of the Fund, the emerging markets bond market consists of countries included in the Standard & Poor’s Emerging BMI, as well as countries that are not high-income OECD (Organization for Economic Co-operation and Development) members as defined by the World Bank, and other emerging markets countries as determined by the Advisor.

The Fund will invest primarily in emerging markets credit default swaps, U.S. Treasury futures, and bonds. By investing in a combination of emerging markets credit default swaps, U.S. Treasury futures, and bonds, the Fund’s portfolio will have the characteristics of emerging markets bonds without having to invest directly in emerging markets bonds. 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. The Fund will normally be a seller of credit protection as it seeks to gain exposure to the emerging markets bond market. U.S. Treasury futures are derivatives that track the prices of specific U.S. Treasury securities. The emerging markets bond market tends to consist of bonds that are rated below investment grade (below BBB-/Baa3) by nationally recognized statistical rating organizations.

As part of its primary strategy, the Fund also expects to invest in other investment companies, consisting of exchange-traded funds (“ETFs”), mutual funds, unit investment trusts, and closed-end investment companies, as well as swap agreements, derivatives, and other financial instruments with economic characteristics comparable to that of the emerging markets bond market as represented by emerging market bonds. Certain of the investment companies in which the Fund may invest may be advised by the Advisor or otherwise affiliated with the Fund.

The Fund derives its exposure to the emerging markets bond market from its investment in credit default swaps and futures, which provide leveraged exposure. Investments in these derivative instruments have the economic effect of creating financial leverage in the Fund’s portfolio because such investments may give rise to losses that exceed the amount the Fund has invested in those instruments. Financial leverage will magnify, sometimes significantly, the Fund’s exposure to any increase or decrease in prices associated with a particular reference asset resulting in increased volatility in the value of the Fund’s portfolio. The value of the Fund’s portfolio is likely to experience greater volatility over short-term periods. While such financial leverage has the potential to produce greater gains, it also may result in greater losses, which in some cases may cause the Fund to liquidate other portfolio investments at a loss to comply with limits on leverage and asset segregation requirements imposed by the Investment Company Act of 1940 or to meet redemption requests.

In addition to its primary strategy, the Fund may, under normal circumstances, buy debt securities to collateralize its derivatives investments, for liquidity purposes, or to enhance yield. The Fund may hold a portfolio of fixed income instruments of varying maturities, but that have an average duration of less than one year. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates and is not simply a measure of time. The longer a security’s duration, the more sensitive it will be to changes in interest rates. In particular, the Fund may hold government money market instruments, such as U.S. Treasury securities and U.S. government agency discount notes and bonds with maturities of two years or less. In addition, the Fund may invest in bank obligations, which may include certificates of deposit, commercial paper, asset-backed commercial paper, unsecured bank promissory notes, bank loans, bankers’ acceptances, and time deposits, as well as other short-term instruments, such as loan participations and repurchase agreements. Bank obligations may be issued or backed by U.S. banks or be U.S. dollar-denominated obligations issued or guaranteed by foreign banks. The Fund will enter into repurchase agreements only with counterparties that are deemed to present acceptable credit risks. The Fund also may invest in high yield securities, known as junk bonds, which are debt securities rated below investment grade (below BBB-/Baa3) by nationally recognized statistical rating organizations, or unrated securities that the Advisor believes are of comparable quality.

The Fund may invest in sovereign debt securities denominated in foreign currencies or the U.S. dollar. The Advisor may attempt, but is not obligated, to reduce foreign currency exchange rate risk by entering into contracts with banks, brokers or dealers to purchase or sell securities or foreign currencies at a future date (“forward contracts”). The Fund also may invest in privately placed securities that have not been registered for sale under the Securities Act of 1933 pursuant to Rule 144A (“Rule 144A Securities”) which are determined by the Advisor to be liquid.

The Fund’s strategy may frequently involve buying and selling portfolio securities to rebalance the Fund’s exposure to various market sectors.

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.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

BANK OLBIGATIONS RISK—The Fund’s investments in bank obligations may expose it to adverse developments in or related to the banking industry. The activities of U.S. and most foreign banks are subject to comprehensive regulations, which, in the case of U.S. regulations, have undergone substantial changes in the past decade. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operations and profitability of domestic and foreign banks. Banks may be particularly susceptible to certain economic factors, such as interest rate changes and adverse developments in the real estate markets. Fiscal and monetary policy and general economic cycles can affect the availability and cost of funds, loan demand and asset quality and thereby impact the earnings and financial conditions of banks. Obligations of foreign banks, including Yankee obligations, are subject to the same risks that pertain to domestic issuers, notably credit risk and market risk, but are also subject to certain additional risks such as adverse foreign political and economic developments, the extent and quality of foreign government regulation of the financial markets and institutions, foreign withholding taxes and other sovereign action such as nationalization or expropriation.

EXTENSION RISK—An issuer may exercise its right to pay principal on an obligation later than expected. This may happen when there is a rise in interest rates. Under these circumstances, the value of the obligation will decrease and the Fund's performance may suffer from its inability to invest in higher yielding securities.

FOREIGN ISSUER EXPOSURE RISK—The Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. The Fund’s investments in foreign securities and foreign issuers are subject to additional risks in comparison to U.S. securities and U.S. issuers, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity, limited legal recourse and higher transactional costs.

INVESTMENT IN INVESTMENT VEHICLES RISK—Investing in other investment vehicles, including, ETFs, closed-end funds, affiliated short-term fixed-income funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment vehicles’ expenses. Consequently, an investment in the Fund entails more direct and indirect expenses than a direct investment in the underlying investment vehicles.

INVESTMENT TECHNIQUE RISK—Some investment techniques of the Fund, such as its use of derivatives and other commodity-linked financial instruments to seek to achieve its investment objective, may be considered aggressive. 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. Such investment techniques may not consistently produce desired results and may be limited by legislative, regulatory, or tax developments.

SOVEREIGN DEBT RISK—Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in money market instruments issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities, and enters into repurchase agreements collateralized fully by U.S. government securities. The Fund also may invest in other securities that are determined to be “Eligible Securities” as defined in Rule 2a-7 of the Investment Company Act of 1940 (the “1940 Act”), including, but not limited to Eurodollar Time Deposits, securities issued by the International Bank for Reconstruction and Development (also known as The World Bank), and high-quality commercial paper certificates of deposit, and short-term corporate bonds. The Fund operates in compliance with U.S. Securities and Exchange Commission 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.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As 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 the principal risks described below.

INCOME RISK—Income Risk involves the potential for decline in the Fund’s yield (the rate of dividends the Fund pays) in the event of declining interest rates.

REPURCHASE AGREEMENT RISK—The Fund’s 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 RISK—The Fund’s 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.

PERFORMANCE INFORMATION

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

Effective upon the close of business on June 15, 2012, the Fund converted its existing Investor Class Shares, Advisor Class Shares, A-Class Shares, C-Class Shares and Investor2 Class Shares with a single share class. Therefore, the returns shown in the bar chart below for periods prior to June 15, 2012 are the returns of the Fund’s former Investor Class Shares, which were subject to the same fees and expenses as the shares offered in this Prospectus. The Fund’s shares would have annual returns substantially similar to those of the former Investor Class Shares because they are invested in the same portfolio of securities. The variability of performance over time provides an indication of the risks of investing the Fund. Of course, this past performance (before taxes) does not necessarily indicate how the Fund will perform in the future.

[1]	The Total Annual Fund Operating Expenses in this fee table may not correlate to the expense ratios in the Fund’s financial highlights and financial statements because the financial highlights and financial statements reflect only the operating expenses of the Fund and do not include Acquired Fund Fees and Expenses, which are fees and expenses incurred indirectly by the Fund through its investments in certain underlying investment companies.
[2]	The Advisor has contractually agreed to reduce fees and/or reimburse expenses to the extent necessary to keep net operating expenses for Class H shares (including Rule 12b-1 fees (if any), but exclusive of brokerage costs, dividends on securities sold short, expenses of other investment companies in which the Fund invests, interest, taxes, litigation, indemnification, and extraordinary expenses (as determined under generally accepted accounting principles) (“Excluded Expenses”)) from exceeding 1.35% of the Fund’s Class H shares average daily net assets. The Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement includes Excluded Expenses and, thus, from time to time may be higher than 1.35%. This Agreement may be terminated only with the approval of the Fund’s Board of Trustees. In any event, this undertaking will continue for at least twelve months from the date of this Prospectus.
[3]	If you exchange your Class A shares or Class C shares of another Guggenheim Investments fund for shares of the Fund, and your Class A shares or Class C shares are subject to a deferred sales charge at the time of the exchange, no deferred sales charge will be incurred on the exchange itself. However, any such deferred sales charge will be assessed at the time you redeem your shares of the Fund.
