The ProShares UltraPro Short 20+ Year Treasury (TTT) is a mutual fund that seeks to provide investors with a leveraged inverse exposure to the performance of the 20+ Year Treasury Bond Index. This means that the fund aims to deliver three times the inverse daily return of the index, making it a high-risk, high-reward investment option. The fund is designed for investors who are looking to profit from a decline in long-term Treasury bond prices. However, it is important to note that this fund is not suitable for all investors and should be carefully considered before making any investment decisions.
