RMQHX	Monthly Rebalance NASDAQ-100® 2x Strategy Fund

The Fund is very different from most mutual funds in that it seeks to provide calendar month leveraged investment results 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. Investors should note that the pursuit of a leveraged investment goal 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 (i.e., 200% of the performance of the NASDAQ-100 Index®) over a period of time different than a full calendar month. This means the return of the Fund for a period of longer than a full calendar month will be the result of each month'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 different than a full calendar month, whether for a period shorter 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 Fund’s benchmark for the full calendar month. An investor who purchases shares on a day other than the last business day of a calendar month will generally receive more, or less, than 200% exposure to the underlying index from that point until the end of the calendar month.

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 monthly leveraged investment results, and (c) 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 does not seek to provide investment results on a daily basis or for periods different than a full calendar month that match the performance of its benchmark, but rather seeks to provide investment results that match the performance of its benchmark on a full calendar month basis. The Fund seeks 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 decline 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.

Monthly Rebalance NASDAQ-100® 2x Strategy Fund

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 benchmark 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.

INVESTMENT OBJECTIVE

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.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy, hold and sell Class H shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

SHAREHOLDER FEES (fees paid directly from your investment)

N/A

ANNUAL FUND OPERATING EXPENSES

(expenses that you pay each year as a percentage of the value of your investment)

	Class H
Management Fees	0.90 %
Distribution and/or Service (12b-1) Fees	0.25 %
Other Expenses1	0.69 %
Short Sales Dividend and Interest Expense	0.09%
Remaining Other Expenses	0.60%
Total Annual Fund Operating Expenses	1.84 %
Fee Waiver (and/or expense reimbursement)2,3	-0.51 %
Total Annual Fund Operating Expenses After Fee Waiver (and/or expense reimbursement)	1.33 %

“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 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.

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 (including one year of capped expenses each period) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$135	$529	$948	$2,117

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 695% 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.

PRINCIPAL INVESTMENT STRATEGIES

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 and swaps on exchange-traded funds (“ETFs”), futures contracts, and options on securities, futures contracts, and stock indices. The Fund’s investment in derivatives referencing (i) the underlying index, or (ii) securities included in the underlying index, serves as a substitute for investments in each of the securities of companies included in the underlying index and will be counted towards the Fund’s 80% investment policy (as set forth below). While the Fund may write (sell) and purchase swaps, it expects primarily to purchase swaps. Swap agreements 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 also may 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. These options contracts will be counted towards the Fund’s 80% policy (as set forth below). 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 also may 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. 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 NASDAQ-100 Index® and securities and financial instruments with economic characteristics that should perform similarly to the securities of companies in the NASDAQ-100 Index®.

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

SUMMARY PROSPECTUS | 2

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.

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 $17.5 billion to $4.8 trillion as of June 30, 2026. 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 and Software Industry, separate industries 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, Health Care 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. 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.

The Fund may invest a portion of its assets, and at times, 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 various purposes, including for liquidity management purposes (e.g., to increase yield on liquid investments used to collateralize derivatives positions) or when such investment companies present a more cost-effective investment option than direct investments in the underlying securities. 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.

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.

Asset-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 asset-backed securities, including residential mortgage-backed securities, commercial mortgage-backed securities and other structured finance investments, generally receive payments that are part interest and part return

3 | SUMMARY PROSPECTUS

of principal. These payments may vary based on the rate at which the underlying borrowers pay off their loans. As a result, asset-backed securities are particularly subject to credit risk and borrower defaults on the obligations underlying the asset-backed security will result in losses. In addition, asset-backed securities are typically particularly sensitive to changes in interest rates, which can cause the prices of asset-backed securities to be increasingly volatile and adversely affect the Fund’s holdings of asset-backed securities. Some asset-backed securities, including mortgage-backed securities, may have structures that make their performance based on changes in interest rates and other factors difficult to predict, causing their prices to be volatile. In particular, during periods of falling interest rates, asset-backed securities are more likely to be called or prepaid, which can result in the Fund having to reinvest proceeds in other investments at a lower interest rate or less advantageous terms, which would adversely affect the Fund. Asset-backed securities are also particularly subject to market, liquidity, valuation, prepayment and extension risks and are also subject to risk of impairment of the value of the underlying asset.

Collateralized Loan Obligations (“CLO”) and Collateralized Debt Obligations (“CDO”) Risk—Through its investments in other investment companies, the Fund may have exposure to CLOs. CLOs bear many of the same risks as other forms of asset-backed securities, including interest rate risk, credit risk and default risk. As they are backed primarily by commercial loans, CLOs also bear many of the same risks as investing in loans directly. However, in addition to the risks associated with investment in commercial loans, the complex structure and highly leveraged nature of a CLO poses additional risks, including but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the Fund may invest in CLOs that are subordinate to other classes; and (iv) the complex structure of the CLO may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. CLOs incur indebtedness by issuing classes or “tranches” that vary in risk and yield. CLOs may experience substantial losses attributable to loan defaults or trading losses. Such losses on the underlying assets are borne first by the holders of subordinate tranches, which may take the form of an equity interest. The Fund’s investments in CLOs may decrease in market value or income when the CLO’s assets experience loan defaults or credit impairment, losses that extend the most subordinate tranches, or market anticipation of loan defaults and investor aversion to CLO securities as a class.

CDOs are structured similarly to CLOs and bear many of the same risks as CLOs including interest rate risk, credit risk and default risk. CDOs are subject to additional risks because they are backed by pools of assets other than commercial loans, including securities (such as other asset-backed securities) and synthetic instruments or bonds, and may be highly leveraged. Like CLOs, losses incurred by a CDO are borne first by holders of the most subordinate tranches. Accordingly, the risks of CDOs depend largely on the type of underlying collateral and the tranche of CDOs in which the Fund invests. Moreover, CDOs that obtain their exposure through synthetic investments are exposed to risks associated with derivative instruments.

The terms of many structured finance investments, including CLOs and CDOs, are tied to the Secured Overnight Financing Rate, known as SOFR, or other reference rates. These relatively new and developing rates may not match the reference rate applicable to the underlying assets related to these investments and may adversely affect the Fund and its investments in CLOs and CDOs, including their value, volatility and liquidity. CLOs, CDOs and their underlying loan obligations are typically not registered for sale to the public and therefore are subject to certain restrictions on transfer and sale, potentially subjecting them to increased liquidity risk as compared to other types of investments. As a result, the proceeds from the sale of CLO securities may not be readily available to meet the Fund’s redemption or other obligations and the Fund may be unable to acquire or dispose of the securities at a price and time that are advantageous to the Fund.

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 full calendar month, before accounting for fees and fund expenses. Compounded returns are the result of reinvesting monthly returns over periods greater than a single month. The Fund’s compounded returns for periods greater than a full calendar month 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.

SUMMARY PROSPECTUS | 4

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 monthly 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 performance of the Fund’s underlying index on a monthly basis.

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 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 performance of the underlying index; conversely, the shaded areas in the table below represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.

Index Performance		Annualized Volatility

60%	120%	149%	140%	105%	56%	-2%

The underlying index’s annualized historical volatility rate for the five-year period ended June 30, 2026 is 20.74%. The underlying index’s highest one-year volatility rate during the five-year period is 26.55%. The underlying index’s annualized performance for the five-year period ended June 30, 2026 is 16.68%.

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 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 monthly investment objective will be more acute when the underlying index has

5 | SUMMARY PROSPECTUS

an extreme intra-month movement approaching 50%. In addition, as a result of compounding, the Fund’s performance for periods greater 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.

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.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed income or other debt instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived by market participants, rating agencies, pricing services or otherwise to be unable or unwilling, to pay interest or repay principal on time, defaults or otherwise fails to meet its obligations. Actual or perceived changes in economic, social, public health, financial or political conditions in general or that affect a particular type of instrument, issuer, guarantor or counterparty can reduce the ability of the party to meet its obligations, which can affect the credit quality, liquidity and/or value of an instrument. The value of an instrument also may decline for reasons that relate directly to the issuer, guarantor or counterparty, such as management performance, financial leverage and reduced demand for goods and services or an actual or perceived change in financial condition or reputation. The issuer, guarantor or counterparty could also suffer a rapid decline in credit rating, which would adversely affect the value, price volatility and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Depositary Receipt Risk—The Fund may hold the securities of non-U.S. companies in the form of depositary receipts. The underlying securities of the depositary receipts 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 depositary receipts 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—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, if any, 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

SUMMARY PROSPECTUS | 6

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.

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 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. A decline in the value of equity securities held by the Fund will adversely affect the value of your investment in the Fund. 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. The Fund may lose a substantial part, or even all, of its investment in a company’s stock.

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, carry unique, additional and heightened risks when compared to U.S. securities, including, but not limited to: currency fluctuations; adverse political (including geopolitical), social and economic developments; trade restrictions (including tariffs) or other government restrictions by the U.S. or other governments; unreliable, untimely or less publicly available information; less government supervision; reporting, accounting, and auditing standards that are not comparable to those in the United States; less liquidity and more volatility; limited legal recourse; and higher transactional costs.

High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) are regarded as predominantly speculative by certain rating agencies with respect to the issuer’s continuing ability to meet principal and interest payments. These securities generally present additional risks compared to investment grade bonds and are typically less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, and present more credit and default risk, including risk of loss (which may be substantial or total loss) of income and principal, than investment grade bonds. The price of high yield securities tends to be subject to greater volatility due to issuer-specific factors, such as operating results and outlook, and to real or perceived adverse economic and competitive industry conditions. High yield securities

7 | SUMMARY PROSPECTUS

may be issued by companies that are restructuring, are smaller and less credit worthy or are more highly leveraged or indebted than other companies or are financially distressed, and therefore they typically have more difficulty making scheduled payments of principal and interest than issuers of higher rated investments. Under unusual or adverse economic, market or political conditions, high yield securities may be particularly susceptible to default risk and increased default rates. In the event of default, the Fund may incur additional expenses to seek recovery or to negotiate new terms with a defaulting issuer. Based on its investment strategies, a significant portion of the Fund’s investments (directly or indirectly) can be comprised of high yield, below investment grade and unrated securities and thus particularly prone to the foregoing risks, which may result in losses to 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 industries described below. The industries in which the underlying index components, and thus the Fund's assets, may be concentrated will vary as the composition of the underlying index changes over time.

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.

Software Industry. As a result of the Fund's concentration in the Software Industry, the Fund is subject to the risks associated with that Industry. The Software Industry includes companies engaged in developing and producing software designed for specialized applications for the business and consumer markets, including enterprise and technical software, cloud-based software and companies engaged in bitcoin mining, and in developing and producing software for operating systems and platforms, database management software and firewalls. The prices of the securities of issuers in the Software 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, challenges related to bringing products to market, and rapid obsolescence of products. In addition, many software companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by software companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies' technology. Legislative or regulatory changes and increased government supervision also may affect companies in the Software Industry. The Software 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 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,

SUMMARY PROSPECTUS | 8

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.

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—The Fund may seek to gain certain exposure through investments in other investment vehicles. Investing in other investment vehicles, including ETFs, closed-end funds, short-term funds advised by the Advisor and/or its affiliates, 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 or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF or a listed closed-end fund are subject to, among other risks, the risk that the shares may trade at a discount or premium relative to the NAV of the shares and the listing exchange may halt trading of the shares.

Investment in Loans Risk—The Fund may invest in loans directly or indirectly through assignments or participations. Investments in loans, including loan syndicates and other direct lending opportunities, involve special types of risks, including credit risk, interest rate risk, counterparty risk, prepayment risk, risk of subordination to other creditors, extension risk, and risk of insufficient or lack of protection under the federal securities laws. Loans may offer a fixed or floating interest rate. Loans are often below investment grade and may be unrated. The Fund’s investments in loans also can be difficult to value accurately, because of, among other factors, limited public information regarding the loan or the borrowers and may be more susceptible to liquidity risk than fixed-income instruments of similar credit quality and/or maturity. The Fund also is subject to the risk that the value of any collateral for the loan may be insufficient or unavailable to cover the borrower’s obligations should the borrower fail to make payments, become insolvent, or otherwise default. This risk is increased if the Fund’s loans are secured by a single asset. The Fund may also invest in loans that are not secured by collateral which typically present greater risks than collateralized loans. Transactions in loans are often subject to long settlement periods and often require consent from borrowers and/or an agent acting for the lenders, thus potentially limiting the ability of the Fund to invest sale proceeds in other investments and to use proceeds to meet its current redemption obligations. The Fund thus is subject to the risk of selling other investments at disadvantageous times or prices or taking other actions necessary to raise cash to meet its redemption obligations. Participations in loans may subject the Fund to the credit risk of both the borrower and the seller of the participation and may make enforcement of loan covenants, if any, more difficult for the Fund as legal action may have to go through the seller of the participation (or an agent acting on its behalf). Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower’s and the credit group’s operations or assets and by providing certain information and consent rights to lenders. In addition to operational covenants, loans and other debt obligations often contain financial covenants which require a borrower and the related credit group to satisfy certain financial tests at periodic intervals or to maintain compliance with certain financial metrics. The Fund is exposed to, including through investment in underlying funds, loans and other similar debt obligations that are sometimes referred to as “covenant-lite” loans or obligations, which generally are loans or other similar debt obligations that lack financial maintenance covenants or possess fewer or contingent financial maintenance covenants and other financial protections for lenders and investors. These "covenant-lite" loans or similar debt obligations are particularly subject to the risks associated with investments in loans as described above.

9 | SUMMARY PROSPECTUS

Large-Capitalization Securities Risk—The Fund is subject to the risk that large-capitalization securities may underperform 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. 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 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).

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, 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.

SUMMARY PROSPECTUS | 10

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.

Prepayment and Extension Risk—Prepayment risk is the risk that the principal on mortgage-backed securities, other asset-backed securities or any debt security with an embedded call option may be prepaid at any time, which could reduce the security’s yield and market value. In the case of prepayment risk, if the investment is converted, prepaid or redeemed before maturity, the portfolio manager may not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced yield to the Fund. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Conversely, extension risk is the risk that an unexpected rise in interest rates will extend the life of a mortgage- or asset-backed security beyond the prepayment time. If the Fund’s investments are locked in at a lower interest rate for a longer period of time, the portfolio manager may be unable to capitalize on securities with higher interest rates or wider spreads.

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 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.

11 | SUMMARY PROSPECTUS

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.

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.

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.

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.

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

SUMMARY PROSPECTUS | 12

trading in a contract that exceeds such limits. If a trading halt occurs, the Fund may temporarily be unable to 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.
