This Short ProShares ETF seeks a return that is -1x the return of an index or other benchmark (target) for a single day, as measured from one NAV calculation to the next. Due to the compounding of daily returns, ProShares' returns over periods other than one day will likely differ in amount and possibly direction from the target return for the same period. These effects may be more pronounced in funds with larger or inverse multiples and in funds with volatile benchmarks. Investors should monitor their holdings consistent with their strategies, as frequently as daily. For more on correlation, leverage and other risks, please read the prospectus.

Index performance returns do not reflect any management fees, transaction costs or expenses. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not guarantee future results. For standardized returns and performance data of the fund current to the most recent month end, see Performance. See the prospectus for more information.
