It's OK. You had seemed to express some doubt that FAZ could fall below $8.00 or $7.50. But you shouldn't doubt that it will. It's a mathematical certainty that it will, and then it will be R/S'ed again.
And so will FAS at some point.
But that's not a bad thing. These can't return a daily 3X without sacrificing long term price. It's just how they work.
