cdcaveman and kapw7, sorry for not getting back sooner.
I'm posting this as a reply to our previous conversation, and also for luisHK who wrote in another thread about investing in Long vol during this low vol period.
Here is an idea that I explored once, albeit in my very unsophisticated manner (no quantification of slope, vol of vol, etc;! ) Just copy-pasting from my notes:
Long SPY Put at -7%, Short VIX Call spread at around k1=20 / k2=25, when established during periods of low vol (VIX < 20) seems to work rather well. What it does is serve as a way to purchase an SPY Put at a discount or even for a small credit. It's basically a disaster-protection hedge and/or more-fat-tails-than-expected profit-making strategy.
(Initially, I look at the -0.25 delta Puts, but somehow ended up settling on the more crude -7% strike, don't remember why...)
Details : We establish the spread at least 6 weeks before expiry. In the past few years (SPY ~ 120 to 140), typically, the SPY Put at -7% (when VIX < 20) costs $130 (and even as low as half of that). The VIX 20/25 Call spread costs the same => max loss = -500 + 65 = -$435. The profit when SPY does fall around 7% or more is humongous. Debit of $65 vs. profit of $440 to $1000.
Given that vol is mean-reverting, you can probably get away with realizing the gains on the Put and leaving the Call spread open to expire below 20!
