Such ETFs often "reset" daily, meaning that they are designed to achieve their stated objectives on a daily basis. Due to the effect of compounding, their performance over longer periods of time can differ significantly from the performance (or inverse of the performance) of their underlying index or benchmark during the same period of time. This effect may be enhanced during the periods of increased market volatility. Consequently, leveraged ETFs may not be suitable as long-term investments.
