Whoa Risk....
Moreover, why is +gamma a losing strategy if the market stagnates. It all depends on where you select your strikes and how play the strategy. Also, the modelling I have done in selecting the stirkes leads to the most profit IF the market stagnates in a range. I think you are only looking at the GOOG trade ( a fun direction bet) and the one OTM SPX I also tested but I have described how I would use the Cross-Flys much like the diagonal positions.
I like you Phil. Don't take it so personally. It simply seems like "spread of the month". I had some cramps when you started talking about skew and the lack of vega. A double dose of Midol cleared it right up.
To answer your question; long gamma = short theta in a single market. It's a delta play of you're trading out-strikes.
In reference to you slightly backhanded reference to my reliance on greeks. I couldn't tell you my greek position at the moment. I don't run pricing beyond what gives me a raw daily/weekly/yearly IV and a global VaR, which I paid plenty in purchasing. I can make an educated guess, which in all honesty would be pretty accurate, but I don't feel the need. The exotic positions are easy to price, but hard to model; or so the saying goes.
I was the first to give you a high-five on that $6,000 credit you sold with a week to expiration -- so I am really not playing the bad guy here. Congrats on the GOOG and SPX vertical this week.
. I was getting it for being both + and - gamma so where do I go next?
