The Xtrackers S&P 500 Inverse Daily Swap ETF aims to deliver the opposite of the daily performance of the S&P 500 by using swap agreements to hold short positions on the top 500 U.S. blue-chip stocks. This means that if the S&P 500 decreases in value on a given day, the ETF is designed to increase, and if the index rises, the ETF is expected to decline. The fund achieves this inverse exposure through derivatives, focusing specifically on these major U.S. equities to mirror the opposite daily movements of the S&P 500 index.
