Quote from Chuck Krug:
best way to hedge a portfolio of 60 short stocks?
buy calls
buy futures
buy etf (spy,etc)
have i overlooked anything?
The benefit of shorting constituents is down and out skew on the index. I would treat the "sixty" as an index and sell puts (ratio) in 2Xs. Short 60 stocks -> short 2x (short-share lots) the 20-delta put in SPY. You can beta-weight, but you'll trade more conservatively by sticking to the 2:1 ratio. There are many advantages to this (long disp) hedge. Use NDX or Qs if it's largely tech.
You're in a synthetic straddle, initially short delta, with gammas reduced by skew and the dispersion effect. The primary risk is correlation.
