As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified. The effect of leverage on the Fund will generally cause the Funds performance to not correlate to the performance of the Funds benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each days compounded returns over the period, which will very likely differ from twice the inverse return of the Funds underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Funds cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Funds stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below). The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.falsefalsefalsexbrli:stringItemTypestringCustom Element.No definition available.false0Supplement (Text Block)4false 4rr_ObjectiveHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00INVESTMENT OBJECTIVE falsefalsefalsexbrli: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.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less.

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

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

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