This fund aims to achieve daily investment results that are three times the inverse (or opposite) of the daily performance of the S&P Regional Banks Select Industry Index, prior to accounting for fees and expenses. To accomplish this, the fund primarily allocates at least 80% of its net assets (including any borrowed capital) to financial instruments like swap agreements, futures contracts, and short positions, which collectively provide this inverse and leveraged exposure to the index. The underlying benchmark, the S&P Regional Banks Select Industry Index, is a modified equal-weighted index designed to measure the performance of stocks from the regional banks sub-industry, as defined by GICS, within the S&P Total Market Index.
