ProShares Short Dow30 (the Fund), formerly Short Dow30 ProShares, seeks daily investment results that correspond to the inverse daily performance of the Dow Jones Industrial Average (DJIA). The DJIA is a price-weighted index maintained by editors of The Wall Street Journal. The DJIA includes 30 large-cap, blue-chip United States stocks, excluding utility and transportation companies. Components are selected through a discretionary process with no pre-determined criteria except that components should be established United States companies. The DJIA is not limited to traditionally defined industrial stocks and the Index serves as a measure of the entire United States market, covering such diverse industries as financial services, technology, retail, entertainment and consumer goods. The Fund takes positions in securities and/or financial instruments that, in combination, should have similar daily return characteristics as –100% of the daily return of the Index.
