Here is one XIV scenario I'm looking for:
A sell signal followed by a nice spike in the VIX, over a couple of days, to create a quick buy signal. This quick spike would push the XIV down to 81.19, or a really large spike pushing the XIV down to 66.31
It would, imo ,take a HUGE news event to hit 66.31, but doable. Currently, there's no fear in the markets, so they're looking for any excuse to sell off and take profits.
