XIV previous discussion about VIX spikes providing XIV buy opp every 5-6 weeks. That cycle has accelerated lately with spikes occurring every 5-15 trading days. Also VIX "baseline" for next spike is rising from 9-11 area that worked until recently to 10-12 area. VIX has moved down into that level from recent spike and XIV appears to have settled into a pattern where the higher probablity move is not to 90-95 but back to a VIX spike buy opportunity in the mid 70's.
