GUSH seeks to deliver 200% of the daily performance of the S&P Oil & Gas Exploration & Production Select Industry Index. Unlike State Streets XOPan unlevered fund tracking the same indexGUSH uses over-the-counter derivatives to achieve its objective. As with all levered and inverse funds, GUSH should not be expected to deliver 2 times the performance of its index for periods longer than one day. Compounding and path-dependency can cause significant deviations over longer time frames, so it's best used for single-day tactical plays. It's worth noting that GUSH's index is equal weighted, market-cap weighting would require extreme concentration in a handful of major firms. As a result, GUSH exhibits a serious small-cap tilt and the elevated market risk that comes with it. GUSH's leverage factor only amplifies the potential for volatility. Trading costs should be taken into consideration. Prior to March 31, 2020, the fund provided 300% daily performance return of the same index.
