Financial Services Fund

INVESTMENT OBJECTIVE

The Financial Services Fund (the "Fund") seeks to provide capital appreciation by investing in companies that are involved in the financial services sector ("Financial Services Companies").

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. Owners of variable annuity and insurance contracts that invest in the Fund also should refer to the variable insurance contract prospectus for a description of fees and expenses that may be deducted at the separate account level or contract level for any charges that may be incurred under a contract. If the information below were to reflect the deduction of insurance charges, fees and expenses would be higher.

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 does not reflect the fees and expenses which are, or may be, imposed under your variable insurance contract. If the Example were to reflect the deduction of such charges, the costs shown would be greater. 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: 

1 Year	3 Years	5 Years	10 Years
$186	$586	$1,011	$2,197

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. 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 97% 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

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Financial Services Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Advisor employs a proprietary quantitative and qualitative methodology to identify Financial Services Companies in which to invest. The methodology utilizes screens based on price, liquidity, and tradability. The securities are then weighted using a proprietary modified capitalization weighting methodology. The portfolio may be further adjusted to comply with regulatory investment limitations or as determined appropriate by the Advisor.

The Fund may invest to a significant extent in the securities of Financial Services Companies that have small to mid-sized capitalizations. Financial Services Companies include commercial banks, savings and loan associations, insurance companies, brokerage companies and real-estate investment trusts ("REITs"). Financial Services Companies also may include companies that are significantly involved in multiple sectors, including the financial services sector. The Fund also may purchase American Depositary Receipts ("ADRs") to gain exposure to foreign Financial Services Companies and U.S. government securities. Under U.S. Securities and Exchange Commission regulations, the Fund may not invest more than 5% of its total assets in the equity securities of any company that derives more than 15% of its revenues from brokerage or investment management activities.

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

In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. As of March 31, 2026, the Fund has significant exposure to the Financials Sector and Real Estate 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. Also, as of March 31, 2026, the Fund's investments are concentrated (i.e., more than 25% of its assets) in securities issued by companies in the Capital Markets Industry, a separate industry within the Financials Sector.

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.

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. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. 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. 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 over-the-counter ("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 net asset value ("NAV") per share. 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.

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.

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.

Industry Concentration Risk-The Fund expects to 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 March 31, 2026, the Fund's investments are concentrated in securities issued by companies in the Capital Markets Industry. As a result of the Fund's concentration in the Capital Markets Industry, the Fund is subject to the risks associated with that Industry. The Capital Markets Industry includes financial institutions primarily engaged in: (i) investment management and/or related custody and securities fee-based services; (ii) investment banking and brokerage services, including equity and debt underwriting, mergers and acquisitions, securities lending and advisory services; and (iii) diversified capital markets activities, including a significant presence in at least two of the following areas: large/major corporate lending, investment banking, brokerage and asset management. The Capital Markets Industry also includes financial exchanges for securities, commodities, derivatives, cryptocurrencies and other financial instruments, and providers of financial decision support tools and products including ratings agencies. The prices of securities of companies in the Capital Markets Industry may fluctuate widely and be significantly affected by stock and bank trading activity, continuing increases in price competition, decreases in fees or fee-related business, including investment banking, brokerage, asset management and other servicing fees, fluctuations in interest rates and other factors which could adversely affect financial markets. Legislative or regulatory changes and increased government supervision also may affect companies in the Capital Markets Industry. The Capital Markets Industry is a separate industry within the Financials Sector.

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.

Mid-Capitalization Securities Risk-The Fund is subject to the risk that mid-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Securities of mid-capitalization companies may be more speculative, volatile and less liquid than securities of large companies. Mid-capitalization companies tend to have inexperienced management as well as limited product and market diversification and financial resources and may be more vulnerable to adverse developments than large capitalization companies.

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.

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.

Sector Risk-To the extent 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. As of March 31, 2026, the Fund is subject to the Sector Risks described below.

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. 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. 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.

Real Estate Sector Risk. The Fund's investments are exposed to issuers conducting business in the Real Estate Sector. The Real Estate Sector includes companies operating in real estate development and operations. It also includes companies offering real estate-related services and REITs. 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 Real Estate Sector. The performance of companies operating in the Real Estate Sector has historically been cyclical and particularly sensitive to the overall economy and market changes, including declines in the value of real estate or, conversely, saturation of the real estate market, economic downturns and defaults by borrowers or tenants during such periods, increases in competition, limited availability of mortgage funds or other limits to accessing the credit or capital markets, and changes in interest rates.

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 and higher transaction costs. 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.

Small-Capitalization Securities Risk-The Fund is subject to the risk that small-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Securities of small-capitalization companies may be more speculative, volatile and less liquid than securities of larger companies. Small-capitalization companies tend to have inexperienced management as well as limited product and market diversification and financial resources and may be more vulnerable to adverse developments than mid- or large-capitalization companies.

Temporary Defensive Investment Risk-The Advisor generally does not attempt to take defensive positions in the Fund in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.

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 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 fully invest its assets, which could adversely affect performance, and may prevent the Fund from achieving its investment objective.

PERFORMANCE INFORMATION

The bar chart below shows the performance of the shares of the Fund from year to year. The variability of performance over time provides an indication of the risks of investing in the Fund.
