TMV provides daily inverse (-3x) exposure to the ICE U.S. Treasury 20+ Year Bond Index. Using a combination of swaps and futures, TMV gives investors -3x exposure to daily moves in T-bonds with more than 20 years left to maturity. The daily reset means investors shouldn't expect the leverage factor to hold constant over investment horizons greater than one day. In short, the fund is a valid option for tactical positioning/hedging against rising interest rates, but it's important to keep in mind that the -3x leverage results in greater impact from the effects of compounding. As a levered product, TMV is not a buy-and-hold ETF, it's a short-term tactical instrument. Prior to May 2, 2016, TMV tracked the NYSE 20+Year Treasury Bond Index. The change had minimal impact on investors exposure. Effective February 27, 2026, the fund replaced the term Shares in its name with ETF.
