The investment seeks daily investment results that correspond to two times (2x) the daily performance of the S&P SmallCap 600®. The fund invests in securities and derivatives that ProShare Advisors believes, in combination, should have similar daily return characteristics as two times (2x) the daily return of the index. The index is a measure of small-cap company U.S. stock market performance. It is a float-adjusted, market capitalization-weighted index of 600 U.S. operating companies selected through a process that factors in criteria such as liquidity, price, market capitalization, financial viability and public float. The fund is non-diversified.
