This ETF seeks a return of -200% of the return of an index (target) for a single day. Due to the compounding of daily returns, 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.

The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance quoted. For standardized returns and performance data current to the most recent month end, see Performance. See the prospectus for more information.

There is no guarantee any ProShares ETF will achieve its investment objective.

Shares of any ETF are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns.

UltraShort ProShares should lose money when their benchmark indexes rise—a result that is opposite from traditional ETFs. UltraShort ProShares entail certain risks, including, in some or all cases, aggressive investment techniques (futures contracts, options, forward contracts, swap agreements and similar instruments), correlation or inverse correlation, leverage and market price variance, all of which can increase volatility and decrease performance. ProShares are nondiversified and may be more susceptible to single issuer risk than a more diversified fund. Please see the prospectus for a more complete description of these risks.
