The VelocityShares 3x Long Natural Gas ETN (UGAZF) is a mutual fund that seeks to provide investors with three times the daily performance of the S&P GSCI Natural Gas Index. This fund is designed for investors who are bullish on the natural gas market and want to amplify their potential returns. However, it is important to note that this fund is an exchange-traded note (ETN) and not a traditional mutual fund, meaning it carries credit risk and may not track the index perfectly. Investors should carefully consider their risk tolerance and investment goals before investing in UGAZF.
