Quote from rallymode:
risk,
quick question on bear risk reversals. I know you mentioned before that you try to keep the delta <.30 on each leg. Is that the only reason why you rather sell cheaper gamma at the OTM strikes vs gamma closer to the peak?? The only thing that i see is the high delta at the ATM strike that you rather avoid by selling cheaper gamma in return. You've traded these for a long time, are there any other real world insights you'd like to share regarding strike selection?
The dG/dS convexity kinks at approximately 25d, advantageous for hedging >1sigmas. Also, you gain from from the static-gamma losss on the deep otm side.
As you approach 50d per side [same-strike] you're buying concavity and a synthetic futures contract.
