The investment seeks daily investment results, before fees and expenses, of 300% of the inverse (or opposite) of the daily performance of the PHLX Semiconductor Sector Index. The fund, under normal circumstances, invests in swap agreements, futures contracts, short positions or other financial instruments that, in combination, provide inverse (opposite) or short leveraged exposure to the index equal to at least 80% of the fund's net assets (plus borrowing for investment purposes). The index measures the performance of domestic companies engaged in the design, distribution, manufacture and sale of semiconductors. The fund is non-diversified.
