ProShares Inflation Expectations 

Typically, this fund commits a minimum of 80% of its total assets to the securities that constitute its underlying index. This benchmark, in turn, is designed to mirror the performance derived from two key strategies: (i) maintaining a long position in recently issued 30-year Treasury Inflation-Protected Securities (TIPS) and (ii) holding a duration-adjusted short position in U.S. Treasury bonds. The aggregate dollar duration of these short positions is approximately equivalent to that of the TIPS. It's important to note that the fund operates as a non-diversified entity.
