Dagnyt, coach, murray & others,
I'm experimenting with OOM diagonals, CR spreads and backspreads. I'd like to put some thoughts out there for comment.
Diagonals allow you to mitigate some of the downside gamma inherent in credit spreads and to take a position on vega. As others here have pointed out, diagonals can be positive or negative vega depending on spread widths. In order to make the vega bet or lay off some gamma, you have to sacrifice a fair bit of your credit or use very wide strikes, thereby adding to your risk. So far so good.
Putting aside the vega bet for now, and trying to keep things simple, I am finding that a condor with some extra OOM long options take the edge off the gamma ugliness without sacrificing as much of my credit as using a diagonal. Even a ratio of 1.1 or 1.2 favoring the longs has a significant impact. This seems simpler, doesn't it.
Thoughts, comments, flames?
Now allowing for volatility declines to the upside and increases to the downside, you might want to be short vega to the upside and long to the downside (all else equal). How 'bout mixing the approaches - diagonal down, backspreads up? Or a hybrid of backspread/diag to the downside?
I realize I'm not reinventing the wheel here, but I'd appreciate any comments.
PS, Kudos to coach for launching this thread. I've found it invaluable.
