Quote from atticus:
Not theta, vega. I was within a dime of predicting the fly price today ($42), as well as the 26% vol in Nov. Not patting myself on the back, but I trade a lot of vol. I think it's got to go a bit lower.
Quote from newwurldmn:
I was wrong here. I see that in doing the 110's, the pnl is about 2.4 between premium (70 cents) and gamma (1.7).
