This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from 1.5x of the return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).   The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement (Text Block)4false 4rr_ObjectiveHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00INVESTMENT OBJECTIVEfalsefalsefalsexbrli:stringItemTypestringInvestment Objectives/Goals.

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

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

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

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

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph
