It was a huge opportunity to short them today (UVXY/VXX). They drop or gain almost the same in dollar amount, so it really doesn't matter which one, but for me, it's next to impossible to get short shares of UVXY. It was $9 just a few days ago, and it will eventually go back there. Only question is, will there be a crash between now & then? Pull up a one year chart of UVXY, and look at it. Pull up a two year chart of VXX, which has been around longer, and check it out. Only down over time. 1% per day.
