ProShares Ultra 20+ Year Treasury(AMEX:UBT)

UBT provides daily 2x exposure to the ICE U.S. Treasury 20+ Year Bond Index. Using a combination of swaps and futures, UBT gives investors 2x 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 2x leverage results in greater impact from the effects of compounding. As a levered product, UBT is not a buy-and-hold ETF, it's a short-term tactical instrument. Prior to Oct. 14, 2016, UBT changed its underlying index from the Bloomberg Barclays U.S. 20+ Year Treasury Bond Index to the ICE U.S. Treasury 20+ Year Bond Index. The change had minimal impact on investor's exposure.
