The DB Base Metals Double Short ETN (BOM) is a mutual fund that seeks to provide investors with a return that is twice the inverse performance of a basket of base metals. This means that as the base metals market declines, the fund aims to generate a positive return for its investors. The fund is designed for those who are looking to hedge against potential losses in the base metals market or for those who have a bearish outlook on the industry. BOM is an exchange-traded note (ETN), which means it is a type of debt security that tracks an underlying index or asset. This fund is best suited for investors who are willing to take on a higher level of risk in pursuit of potential returns.
