Each leveraged or inverse ProShares ETF seeks a return that is either 300%, 200%, -100%, -200% or -300% of the return of an index or other benchmark (target) for a single day . 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. Investors should monitor their ProShares holdings consistent with their strategies, as frequently as daily. For more on correlation, leverage and other risks, please read the prospectus.
