Quote from DonnaV:
riskarb did you play CME earnings? I threw on a Bear call CS last nite 500/510 for a 4.05 credit....now I'm thinking of doing a put CS ...but then thought what about covert to B-fly by buying 490/500....I'd love your thoughts on doing the IC vs the B-fly...
Yeah, Donna. I sold the Sep 380 combo at an average of 82 last week, forgot the vols, but they were in the high 30s.
You'd need to sell the iron fly with a 500 body strike to convert. I wouldn't want to be neutral at 500. Selling the 60/70 put spread will only net you a $4.00 credit here for the IC.
With this drop in vols, both the IC and fly look like a pass with what you're holding. I would probably take you delta/vega gains on the bear call spread and call it a day with CME.
