The Amundi Daily ShortDAX x2 ETF is designed to provide twice the inverse daily performance of Germany's DAX index. To accomplish this, the fund primarily uses derivative instruments such as futures and swaps to take leveraged short positions on the DAX. This means that if the DAX falls by 1% in a day, the ETF aims to gain 2%, and vice versa. By employing a synthetic replication strategy, the Amundi Daily ShortDAX x2 ETF closely mirrors the performance of the SHORTDAX X2 INDEX, allowing investors to potentially benefit from declines in the German stock market.
