ProShares has launched a third short treasury exchange traded fund (ETF), just in time for bearish investors to play any sentiment that Treasury bonds are in a bubble that’s about to pop.

The latest ETF from ProShares is the ProShares Short 20+Year Treasury (TBF). The ETF debuted today on the NYSE Arca. This ETF is meant to track the index at -100% for no longer than a single day.

The index includes all publicly issued, U.S. Treasury securities that have a remaining maturity greater than 20 years, are non-convertible, are rated investment grade, and have a fixed rate.
