Quote from IV_Trader:
WEBX is out , I don't see vols rising to previous levels. If conditions are right , I will put the following trade on ISRG :
buy 1 atm JAN
sell 2 atm FEB
buy 1 atm MAR
So basically its exactly opposite bet from what you planning to do.
just looked at isrg...assuming earnings are jan 26 or so...after jan expiration...why buy jan and sell feb...jan will trade as usual and feb will hold it's price till earnings are released...then collapse...no?
