The Direxion Daily 20+ Year Treasury Bull & Bear 3X Shares seek daily investment results, before fees and expenses, of 300%, or 300% of the inverse (or opposite), of the performance of the ICE U.S. Treasury 20+ Year Bond Index. There is no guarantee the funds will meet their stated investment objectives.
These leveraged ETFs seek a return that is 300% or -300% of the return of their benchmark index for a single day. The funds should not be expected to provide three times or negative three times the return of the benchmark’s cumulative return for periods greater than a day.
