The fund is an actively managed ETF that seeks to provide total return that matches or outperforms the performance of the ICE U.S. Treasury 20+ Year Index for a calendar quarter, not for any other period. Under normal circumstances, the fund invests at least 80% of its net assets in futures contracts, call options, and put options on U.S. treasury futures, U.S. government securities, such as bills, notes and bonds issued by the U.S. Treasury or fixed income ETFs that invest in U.S. Treasuries.
