The DB Gold Double Short Exchange Traded Notes (DZZ) is a mutual fund that seeks to provide investors with a return that is twice the inverse performance of the daily price movements of gold. This means that as the price of gold decreases, the value of the fund is expected to increase, and vice versa. The fund is designed for investors who are looking to profit from short-term fluctuations in the gold market. It is important to note that this fund is not a traditional mutual fund, but rather an exchange-traded note (ETN), which is a type of debt security that tracks an underlying index or asset.
