It's sort of counter-intuitive. It's like, I trust my analysis enough to write puts but at the same time let me throw some cash away just in case I screw the pooch. I'll spend some time modeling some ideas this weekend. I guess the way to look at it is as catastrophic event insurance. My initial thought is the insurance premium won't pay for itself unless things go totally fucky.A dealer never partakes in his stash. I sell premium I don't buy it.
Having said that it's not a horrible way to give up some alpha for downside protection.
