Based on the stats for the last few years, it seems buying puts on VXX performed far better then buying calls in inverse VIX ETF's like XIV or SVXY. Since the beginning of 2013...
XIV went from 17 to 50
SVXY went from 35 to 95
VXX dropped from 115 to 16
I'd take any of these gains, but to get the best gain% to play for the VIX staying low to moderate I think you are far better off playing for VXX to drop compared to playing XIV/SVXY to rise.
