All of these would work, depends on what you are trying to do and what kind of event caused volatility. You could simply short a really long dates straddle (e.g. Dec 13) - it's pretty much pure vega assuming you deem the implied vol levels high enough. Long-delta 1x2s or put trees on VIX that show good break-even levels is a reasonable way that will not break the bank either.Quote from optionatrix:
How do you short vol? Short VIX futures, long VIX calendars, use VIX options, gamma-delta neutral short SPX time spreads?
All those have time limitations - would you roll forward? You could short VXX and keep it for a while.
I just want to short cash VIX and hang on to it, but it's impossible.
