ProShares UltraShort Energy 

DUG provides (-2x) inverse exposure to the daily performance of the S&P Energy Select Sector Index, a market-cap-weighted index of US oil and gas companies. The funds concentrated portfolio typically includes firms engaged in oil and gas exploration and production, integrated oil and gas, equipment for oil as well as renewable energy, pipelines, and alternative fuel producers. As a levered product with daily resets, DUG is not a buy-and-hold investment and should not be expected to provide index leverage returns greater than a one-day period. Prior to Mar. 20, 2023, the fund was called ProShares UltraShort Energy that tracked the Dow Jones U.S. Oil & Gas Index.
