* The Net Expense Ratio includes management fees, other operating expenses and Acquired Fund Fees and Expenses. If Acquired Fund Fees and Expenses were excluded, the Net Expense Ratio would be 0.95%. The Fund’s adviser, Rafferty Asset Management, LLC (“Rafferty”) has entered into an Operating Expense Limitation Agreement with the Fund. Under the Operating Expense Limitation Agreement, Rafferty has contractually agreed to waive all or a portion of its management fee and/or reimburse the Fund for Other Expenses through September 1, 2024, to the extent that the Fund’s Total Annual Fund Operating Expenses exceed 0.95% of the Fund’s average daily net assets (excluding, as applicable, among other expenses, taxes, swap financing and related costs, acquired fund fees and expenses, dividends or interest on short positions, other interest expenses, brokerage commissions and extraordinary expenses). If these expenses were included, the expense ratio would be higher.

The performance data quoted represents past performance. Past performance does not guarantee future results. The investment return and principal value of an investment will fluctuate. An investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted. Returns for performance under one year are cumulative, not annualized.

Short-term performance, in particular, is not a good indication of the fund’s future performance, and an investment should not be made based solely on returns. Because of ongoing market volatility, fund performance may be subject to substantial short-term changes. For additional information, see the fund’s prospectus.
