SQQQ is a leveraged inverse ETF that seeks daily investment results, before fees and expenses, that correspond to three times the inverse (-3x) of the daily performance of the Nasdaq-100 Index. It is a tactical trading tool designed for sophisticated investors to profit from or hedge against declines in large-cap technology and growth stocks. Due to its daily reset and the effects of compounding, it is intended for short-term use and carries significant risk if held during periods of high market volatility.
