SQQQ is an aggressive take on the large-cap space by providing geared inverse (-3x) exposure to the NASDAQ-100 index an index of 100 tech-heavy firms listed on NASDAQ that excludes financials. To provide this exposure, the fund uses swaps on the popular NASDAQ-100 ETF (QQQ), swaps on the index itself, and futures. As with most inverse and leveraged products, SQQQ is designed to provide this exposure on a daily basis, not over long time horizons. Holding the fund for longer than a day opens the door to the effects of compounding on returns and will be unlikely to realize the stated -3x inverse exposure over time especially in volatile markets.
