Inverse S&P 500® 2x Strategy Fund
The Fund is very different from most mutual funds in that it seeks to provide leveraged inverse investment results on a daily basis and is intended to be used as a short-term trading vehicle. The Fund is not intended to be used by, and is not appropriate for, investors who do not intend to actively manage and monitor their portfolios. The Fund pursues an investment goal which is inverse to 200% of the performance of the Fund's underlying index, a result opposite of most other mutual funds. Investors should note that the pursuit of such leveraged and inverse investment goals has the following implications: • The Fund is 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 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 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 (i.e., -2x) and the cumulative performance of the Fund's benchmark. 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 Fund's underlying index times the stated multiple in the Fund's investment objective, before accounting for fees and fund expenses.
The Fund is not suitable for all investors. The Fund is designed to be utilized only by sophisticated investors, such as traders and active investors employing dynamic strategies. Investors in the Fund should: (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risks of shorting, and (d) intend to actively manage and monitor their investments. Investors who do not understand the Fund or do not actively manage and monitor their investments should not buy shares of the Fund.
The Fund seeks daily exposure to its underlying index equal to -200% of its net assets. As a consequence, the risk of total loss of your investment exists in the event of a gain in the value of the Fund's underlying index in excess of 50%. In short, the risk of total loss of your investment exists.
There is no assurance that the Fund will achieve its investment objective and an investment in the Fund could lose money. The Fund is not a complete investment program.

Inverse S&P 500® 2x Strategy Fund
IMPORTANT INFORMATION ABOUT THE FUND
The Inverse S&P 500® 2x Strategy Fund (the "Fund") is very different from most other mutual funds in that it seeks to provide leveraged investment results that match twice the inverse of the performance of a specific underlying index 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 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 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 (i.e., -2x) and the cumulative performance of the benchmark.
The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risks 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.
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 200% of 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.
FEES AND EXPENSES OF THE FUND
This table describes the fees and expenses that you may pay if you buy, hold and sell Class A shares or Class C shares of the Fund.

"Other Expenses" does not include fees paid to the Fund's swap contract counterparties, or the management fees, performance fees, and expenses of the reference assets or trading vehicles underlying such swap contracts. These fees and expenses, which are not reflected in this Annual Fund Operating Expenses table, are embedded in the returns of the swap contracts (i.e., the fees and expenses reduce the investment returns of the swap contracts) and represent an indirect cost of investing in the Fund.

The Advisor has contractually agreed, through August 1, 2027, to waive and/or reimburse the Fund's expenses in an amount equal to an annual percentage rate of 0.05% of the Fund's average daily net assets. In addition, the Advisor also has contractually agreed, through August 1, 2027, to waive and/or reimburse the Fund's expenses in an additional amount equal to an annual percentage rate of 0.05% of the Fund's average daily net assets. Each agreement shall automatically renew for one-year terms unless the Advisor provides written notice to the Fund of the termination of the agreement. Each agreement may be terminated at any time by the Fund's Board of Trustees and when the Advisor ceases to serve as such.
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 redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 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 the Total Annual Fund Operating Expenses or 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 and most derivatives. If such instruments were included, the Fund's portfolio turnover rate might be significantly higher.
SUMMARY PROSPECTUS | 2
PRINCIPAL INVESTMENT STRATEGIES
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 equity index swaps and swaps on exchange-traded funds, 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 and expects to rebalance the Fund's holdings daily to maintain such exposure. The Fund's investment in derivatives referencing (i) the underlying index, or (ii) securities included in the underlying index, 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 and to securities of companies included in the underlying index. These instruments will be counted towards the Fund's 80% investment policy (as set forth below). 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 inversely to the securities of companies included in the S&P 500® Index.
The S&P 500® Index is a capitalization-weighted index composed of approximately 500 common stocks, which are chosen by the Standard & Poor's Corporation on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $6.7 billion to $4.8 trillion as of June 30, 2026. Certain of the companies included in the S&P 500® Index may be structured as real estate investment trusts ("REITs"). To the extent the Fund's underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. As of June 30, 2026, the underlying index components, and thus the Fund's investments, are concentrated (i.e., more than 25% of its assets) in securities issued by companies in the Semiconductors & Semiconductor Equipment Industry, a separate industry within the Information Technology Sector. The industries in which the underlying index components, and thus the Fund's investments, may be concentrated will vary as the composition of the underlying index changes over time. Also, while the Fund's sector exposure may vary over time, as of June 30, 2026, the Fund has significant exposure to the Communication Services Sector, Consumer Discretionary Sector, Consumer Staples Sector, Financials Sector, Health Care Sector, Industrials Sector, and Information Technology Sector, as each sector is defined by the Global Industry Classification Standard, a widely recognized industry classification methodology developed by MSCI, Inc. and Standard & Poor's Financial Services LLC.
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.
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 imposed by the Investment Company Act of 1940, satisfy margin or collateral requirements, or meet redemption requests.
PRINCIPAL RISKS
The value of an investment in the Fund will fluctuate and is subject to investment risks, which means investors could lose money, including all or part of their investment in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any governmental agency. There is no assurance that the Fund will achieve its investment objective. An investment in the Fund does not constitute a complete investment program. The Fund is subject to certain risks and the principal risks of investing in the Fund are summarized below in alphabetical order, and not in the order of importance or potential exposure. The relative significance of each principal risk summarized below may change over time and you should review each risk carefully because any one or more of these risks may result in losses to the Fund. Please see "More Information About the Trust and the Funds - Principal Risks" in the Fund's Prospectus for a more detailed description of the risks of investing in the Fund.
3 | SUMMARY PROSPECTUS
Compounding Risk-In addition to the correlation risks described under "Correlation Risk", the Fund's returns are subject to the effects of compounding, which generally will cause the Fund's performance to not correlate to the performance of the benchmark over periods greater than a single day, before accounting for fees and fund expenses. Compounded returns are the result of reinvesting daily returns over periods greater than a single day. The Fund's compounded returns for periods greater than a single day will be different than the performance of the benchmark over the same period. The effects of compounding on the performance of the Fund will be more pronounced when the underlying index experiences increased volatility, the greater the leverage employed in the Fund, and over longer holding periods.
Compounding affects the performance of all investments over time, but has a more significant effect on a leveraged index fund because the magnified changes in performance produced by the use of leverage lead to greater increases and decreases in the fund's daily returns which are then compounded over time. The effects of compounding, therefore, have a more significant effect on the Fund because it seeks to match a multiple of the inverse performance of the Fund's underlying index on a daily basis.
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 or interest 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.
The unshaded areas in the table below represent those scenarios where the Fund can be expected to return more than twice the inverse performance of the underlying index; conversely, the shaded areas in the table below represent those scenarios where the Fund can be expected to return the same or less than twice the inverse performance of the underlying index.

The underlying index's annualized historical volatility rate for the five-year period ended June 30, 2026 is 15.85%. The underlying index's highest one-year volatility rate during the five-year period is 20.58%. The underlying index's annualized performance for the five-year period ended June 30, 2026 is 13.41%.
SUMMARY PROSPECTUS | 4
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 isolate the effects of the underlying index volatility and index performance on the return of the Fund, and underscore that the Fund is designed as a short-term trading vehicle for investors who intend to actively monitor and manage their portfolios.
Correlation Risk-A number of factors may affect the Fund's ability to achieve a high degree of correlation with its benchmark, including instances in which the Fund does not hold or have exposure to each component security of the underlying index and the effect of compounding on the Fund's returns, 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 an inverse 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 a single 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 Fund fees and expenses.
Counterparty Credit Risk-The Fund makes investments in financial instruments and OTC-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes insolvent or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease. Counterparty credit risk also includes the related risk of having potentially significant exposure to such counterparty.
Derivatives Risk-Derivatives and other instruments (collectively referred to in this paragraph as "derivatives") pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, market conditions and market risk, imperfect correlations with underlying investments or the Fund's other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation, operational and legal restrictions and risk. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of derivatives may result in leverage, which may cause the Fund to be more volatile and riskier than if it had not been leveraged. Changes in the value of a derivative also may create sudden margin delivery or settlement payment obligations for the Fund, which can materially affect the performance of the Fund, its liquidity, and other aspects of the Fund's risk profile. The Fund's use of derivatives to obtain short exposure may result in greater volatility of the Fund's net asset value ("NAV") per share. If the Advisor is incorrect about its expectations of market conditions, the use of derivatives also could result in a loss, which in some cases may be unlimited. Certain risks are specific to the particular type of derivative instrument in which the Fund may invest. For example, some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty, credit, legal, liquidity and valuation risks.
Futures Contracts Risk-Futures contracts are 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 include imperfect correlation between the movements in the price of the instruments and the price of the underlying assets. In addition, there is a 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 futures 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 also are subject to leverage and liquidity risks. The Fund may invest in standard futures contracts, e-mini futures contracts, and micro e-mini futures contracts depending on the investment exposure needs of the Fund. E-mini futures contracts and micro e-mini futures contracts are similar to standard futures contracts, except that they are electronically traded and e-mini futures contracts generally are one-fifth the size of standard futures contracts and micro e-mini futures contracts generally are one-tenth the size of e-mini futures contracts.
5 | SUMMARY PROSPECTUS
Options Risk-Options and options on futures contracts give the holder of the option the right, but not the obligation, to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. Options are subject to correlation risk because there may be an imperfect correlation between the options and the markets for underlying instruments that could cause a given transaction to fail to achieve its objectives. The successful use of options depends on the Advisor's ability to predict correctly future price fluctuations and the degree of correlation between the markets for options and the underlying instruments. Exchanges can limit the number of options positions that can be held or controlled by the Fund or the Advisor, thus limiting the ability to implement the Fund's strategies. Options also are particularly subject to leverage risk and can be subject to liquidity risk.
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, for certain standardized swaps, must be traded on a designated contract market or swap execution facility. 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. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.
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 Securities Risk-Equity securities include common stocks and other equity and equity-related securities (and securities convertible into stocks). The Fund is exposed to the risks of equity securities primarily through its investments in equity-related derivatives and other investments. The prices of equity securities generally fluctuate more than those of fixed-income investments, may rise or fall rapidly or unpredictably, and may reflect real or perceived changes in the issuing company's financial condition and changes in the overall market or economy. Common stocks generally represent the riskiest investment in a company and dividend payments (if declared) to preferred stockholders generally rank junior to payments due to a company's debtholders. An increase in the value of equity securities to which the Fund has exposure will adversely affect the value of your investment in the Fund.
Industry Concentration Risk-The Fund may concentrate its investments in a limited number of issuers conducting business in the same industry or group of related industries. To the extent the Fund does so, the Fund is more vulnerable to adverse market, economic, regulatory, political or other developments affecting that industry or group of related industries than a fund that invests its assets more broadly. As of June 30, 2026, the underlying index components, and thus the Fund's investments, are concentrated in securities issued by companies in the Semiconductors & Semiconductor Equipment Industry. As a result of the Fund's concentration in the Semiconductors & Semiconductor Equipment Industry, the Fund is subject to the risks associated with that Industry. The Semiconductors & Semiconductor Equipment Industry includes manufacturers of semiconductor equipment, including equipment used in the solar power industry (e.g., raw wafers, gases, liquids and related packaging and material delivery systems), and semiconductors and related products, including manufacturers of solar modules, cells, integrated circuit devices, diodes and light-emitting diodes (LEDs), microprocessors and chips. Companies in the Semiconductors & Semiconductor Equipment Industry rely heavily on technology. The prices of the securities of companies in the Semiconductors & Semiconductor Equipment Industry may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, heavy expenses incurred for research and development of products or services that prove unsuccessful, problems related to bringing products to market, and rapid obsolescence of products. Legislative or regulatory changes and increased government supervision also may affect companies in the Semiconductors & Semiconductor Equipment Industry. The Semiconductors & Semiconductor Equipment Industry is a separate industry within the Information Technology Sector.
Interest Rate Risk-Fixed income and other debt instruments are subject to the possibility that interest rates could change (or are expected to change). Changes in interest rates (or the expectation of such changes) can be difficult to forecast and may adversely affect the Fund's investments in these instruments, such as the value or liquidity of, and income generated by, the investments. Interest rates may change as a result of a variety of factors, and the
SUMMARY PROSPECTUS | 6
change may be sudden and significant, with unpredictable impacts on the financial markets and the Fund's investments. Fixed income and other debt instruments with longer durations are more sensitive to changes in interest rates and, thus, subject to more volatility than similar instruments with shorter durations. Generally, when interest rates increase, the values of previously issued fixed income and other debt instruments decline and when interest rates decrease, the values of fixed income and other debt instruments rise. During periods of rising interest rates, changes in interest rates on adjustable rate securities may lag behind changes in market rates, which may cause the value of such securities to decline until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on adjustable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. The Fund's yield, returns, and performance may be adversely affected by changing interest rates and the Fund's NAV per share may be more volatile during changing interest rate environments. Changes in fiscal, economic, monetary and other policies or measures have in the past, and may in the future, cause or exacerbate the risks associated with changing interest rates. Changes in interest rates may also lead to an increase in Fund redemptions, which may result in high portfolio turnover costs and lower valuations, thereby adversely affecting the Fund's performance.
Large-Capitalization Securities Risk-The Fund is subject to the risk that large-capitalization securities may outperform other segments of the equity market or the equity market as a whole. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and may not be able to attain the high growth rate of smaller companies, especially during extended periods of economic expansion.
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 will have the effect of magnifying tracking error and also may increase the Fund's sensitivity to various risks and interest rate environments.
Liquidity and Valuation Risk-It may be difficult for the Fund to purchase and sell particular investments to meet redemption requests or otherwise within a reasonable time at a fair price, or the price at which it has been valued by the Advisor for purposes of the Fund's NAV, causing the Fund to be less liquid and unable to realize what the Advisor believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. Liquidity and valuation risks are heightened in a changing interest rate or volatile environment particularly for fixed-income and other debt instruments.
Market Risk-The value of, or income generated by, the investments held by the Fund may fluctuate rapidly and unpredictably. These fluctuations may be frequent and significant. In addition, the Fund may incur losses as a result of various market and economic factors, such as those affecting (or perceived to affect) individual companies or issuers or particular industries, or from broader influences, such as general market conditions. In addition, responses to government actions or interventions (including, but not limited, to the threat or imposition of tariffs, trade restrictions, currency restrictions or similar actions) as well as developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters or other conditions or events may cause volatility in financial markets and reduced liquidity in equity, credit and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. Under such conditions, the Fund (or an underlying fund) may experience significant redemption activity by shareholders and could be forced to sell portfolio securities or other assets at unfavorable prices in an effort to generate sufficient cash to pay redeeming shareholders. Certain securities may be difficult to value under such conditions. The Fund's investments may perform poorly or underperform the general securities markets or other types of securities.
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 issuer's securities could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. The Fund may become diversified for periods of time solely as a result of changes in the composition of the underlying index (e.g., changes in the relative market capitalization or weights of one or more index component stocks).
7 | SUMMARY PROSPECTUS
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 and provides for less transparency than a national securities or commodities exchange. 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 rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.
Portfolio Turnover Risk-Periodic 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.
Real Estate Investment Trusts ("REITs") Risk-REITs are classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs own real estate directly and the value of, and income earned by, the REITs depends upon the income of the underlying properties and the rental income they earn. Mortgage REITs make construction, development or long-term mortgage loans and are sensitive to the credit quality of the borrower. Mortgage REITs derive their income from interest earned on such mortgage loans. Hybrid REITs generally hold both ownership interests and mortgage interests in real estate. In addition to the risks pertaining to real estate investments more generally, REITs may be subject to additional risks, including risks associated with the direct ownership of real property, including declines in the value of real estate, risks related to general and local economic conditions, overbuilding and increased competition, increases in property taxes and operating expenses and variations in rental income. REITs (especially mortgage REITs) also are subject to interest rate and prepayment risks. The value of a REIT can depend on the structure of, and cash flow generated by, the REIT. REITs whose investments are concentrated in a limited number or type of properties, investments or narrow geographic area are subject to the risks affecting those properties or areas to a greater extent than a REIT with less concentrated investments. U.S. REITs also are subject to certain provisions under federal tax law. In addition, REITs may have expenses, including advisory and administration expenses, and the Fund and its shareholders will incur its pro rata share of the underlying expenses.
Regulatory and Legal Risk-U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations (or amend regulations) and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund and/or the level of regulation or taxation applicable to the Fund, its investments or service providers. These developments impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.
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.
Sector Risk-To the extent the components of the Fund's underlying index, and therefore, the Fund's holdings, have significant exposure to one or more market sectors, the Fund may be especially sensitive to the developments affecting and risks of such market sectors. The sectors to which the underlying index components, and thus the Fund's assets, may have significant exposure will vary as the composition of the underlying index changes over time. As of June 30, 2026, the Fund is subject to the Sector Risks described below.
Communication Services Sector Risk. The Fund's investments are exposed to issuers conducting business in the Communication Services Sector. The Communication Services Sector includes companies that facilitate communication and offer related content and information through various mediums. It includes telecom and media & entertainment companies, including producers of interactive gaming products and companies engaged in content and information creation or distribution through proprietary platforms. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Communication Services Sector. The performance of companies operating in the Communication Services Sector has historically been closely tied to the performance of the overall economy and also is affected by economic
SUMMARY PROSPECTUS | 8
growth, consumer confidence, attitudes and spending. Increased sensitivity to short product cycles and aggressive pricing, challenges in bringing products to market and changes in demographics and consumer tastes also can affect the demand for, and success of, communication services products and services in the marketplace.
Consumer Discretionary Sector Risk. The Fund's investments are exposed to issuers conducting business in the Consumer Discretionary Sector. The manufacturing segment of the Consumer Discretionary Sector includes automobiles and components, household durable goods, leisure products, and textiles and apparel. The services segment includes hotels, restaurants and other leisure facilities, and distributors and retailers of consumer discretionary products. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Consumer Discretionary Sector. The performance of companies operating in the Consumer Discretionary Sector has historically been closely tied to the performance of the overall economy, and also is affected by economic growth, consumer confidence, attitudes and spending. Changes in demographics and consumer tastes also can affect the demand for, and success of, consumer products and services in the marketplace. Moreover, the Consumer Discretionary Sector encompasses those businesses that tend to be the most sensitive to economic cycles.
Consumer Staples Sector Risk. The Fund's investments are exposed to issuers conducting business in the Consumer Staples Sector. The Consumer Staples Sector includes manufacturers and distributors of food, beverages and tobacco and producers of non-durable household goods and personal products. The Consumer Staples Sector also includes distributors and retailers of other consumer staples products, including food and drug retailing companies. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Consumer Staples Sector. The performance of companies operating in the Consumer Staples Sector has historically been closely tied to the performance of the overall economy, and also is affected by consumer confidence, demands and preferences, and spending. In addition, companies in the Consumer Staples Sector may be subject to risks pertaining to the supply of, demand for, and prices of raw materials.
Financials Sector Risk. The Fund's investments are exposed to issuers conducting business in the Financials Sector. The Financials Sector includes companies involved in banking, financial services (including commercial and residential mortgage finance), consumer finance, capital markets (including asset management and custody banks, investment banking and brokerage), Mortgage Real Estate Investment Trusts (REITs), and insurance. Certain Financials Sector issuers serve as counterparties with which the Fund may enter into derivatives agreements or other similar contractual arrangements. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Financials Sector, which may adversely affect a company's ability to fulfill its obligations as a financial counterparty. Companies operating in the Financials Sector are subject to extensive government regulation, which may limit the financial commitments they can make and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds and may fluctuate significantly when interest rates change or due to increased competition.
Health Care Sector Risk. The Fund's investments are exposed to issuers conducting business in the Health Care Sector. The Health Care Sector includes health care providers and services, companies that manufacture and distribute health care equipment and supplies, and health care technology companies. It also includes companies involved in the research, development, production and marketing of pharmaceuticals and biotechnology products. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Health Care Sector. The performance of companies operating in the Health Care Sector is closely tied to government regulation and policies (such as health care reform measures) and may be affected by government approval of products and services, competitive pricing pressures, rising costs of medical products and services, product obsolescence, and product liability and other similar litigation. In addition, companies operating in the Health Care Sector are heavily dependent on patent and other intellectual property rights, and a company's ability to obtain and protect its patents (or the failure to do so) may affect profitability.
9 | SUMMARY PROSPECTUS
Industrials Sector Risk. The Fund's investments are exposed to issuers conducting business in the Industrials Sector. The Industrials Sector includes manufacturers and distributors of capital goods, such as aerospace and defense, building projects, electrical equipment and machinery, and companies that offer construction and engineering services. The Industrials Sector also includes providers of commercial and professional services including printing, environmental and facilities services, office services and supplies, security and alarm services, human resource and employment services, research and consulting services, and transportation services. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Industrials Sector. The prices of the securities of companies operating in the Industrials Sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar and economic conditions, import controls, worldwide competition, product liability claims, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices. In addition, the products of companies operating in the Industrials Sector may face obsolescence due to rapid technological developments and the rapid introduction of new products.
Information Technology Sector Risk. The Fund's investments are exposed to issuers conducting business in the Information Technology Sector. The Information Technology Sector includes companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment (such as communications equipment, cellular phones, computers and peripherals), electronic equipment and related equipment and materials, and semiconductors and related equipment and materials. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Information Technology Sector. Companies in the Information Technology Sector may be affected by limited product lines, market competition (both domestically and internationally), financial resources and/or personnel. The prices of the securities of companies operating in the Information Technology Sector are closely tied to increased sensitivity to short product cycles and product obsolescence, aggressive pricing, and problems with bringing products to market. Failure to introduce new products, develop and maintain a loyal customer base, or achieve general market acceptance for products could have a material adverse effect on a company's business. In addition, companies in the Information Technology Sector are heavily dependent on intellectual property and the loss of patent, copyright and trademark protections may adversely affect the profitability of these companies.
Shareholder 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.
Short Sale and Short Exposure Risk-Short selling a security involves selling a borrowed security with the expectation that the value of that security will decline, so that the security may be purchased at a lower price when returning the borrowed security. A short exposure through a derivative exposes the Fund to counterparty credit and leverage risks. The loss on a short sale or other short exposure, which, in some cases, may be theoretically unlimited, may be greater than a direct investment in the security itself 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, 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-The Fund typically will hold futures contracts and short-term options. The major exchanges on which these contracts are traded, such as the Chicago Mercantile Exchange, have established limits on how much the trading price of a futures contract or option may decline over various time periods within a day, and may halt trading in a contract that exceeds such limits. If a trading halt occurs, the Fund may temporarily be unable to
SUMMARY PROSPECTUS | 10
purchase or sell certain securities, futures contracts or options. Such a trading halt near the time the Fund prices its shares may limit the Fund's ability to use leverage and fully invest its assets, which could increase tracking error and adversely affect performance, 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. U.S. government securities are subject to the risks associated with fixed income and debt securities, particularly interest rate risk and credit risk. In addition, U.S. government securities not backed by the full faith and credit of the U.S. government involve credit risk that is greater than other types of U.S. government securities.
