The investment seeks daily investment results, before fees and expenses, of 300% of the daily performance of the S&P 500® Index. The fund, under normal circumstances, invests at least 80% of its net assets (plus borrowing for investment purposes) in financial instruments, such as swap agreements, securities of the index, and exchange-traded funds ("ETFs") that track the index, that, in combination, provide 3X daily leveraged exposure to the index, consistent with the fund's investment objective. The index is designed to be comprised of stocks that are the 500 leading, large-cap U.S.-listed issuers. The fund is non-diversified.
