These ETFs have an objective (target) for a single day. Due to the compounding of daily returns, returns for these ETFs 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 holdings consistent with their strategies, as frequently as daily. These ETFs are not regulated under the Investment Company Act of 1940. Investing in these ETFs involves significant risks. There is no guarantee any ProShares ETF will achieve its daily objective. Investors could lose all or substantially all of their investment. These ETFs use leverage and may invest in financial instruments such as swap agreements, forward contracts, and futures and options, resulting in greater volatility than investments in traditional securities and which may cause large losses. These ETFs are not suitable for all investors.
