Wait, so now that you work directly with making a market in options, you don't even use BS because you found another better inefficiency that is based on the data. I mean, dude, that is my very point.LOL,I was hoping you wouldnt ask that. I left the IB world a while ago and we did price off of BS,but I havent used it since . FWIW,I was the trader,not the quant.
I started as a market maker on the trading floors,and I now make markets in selected equities options..No need for any modeling...First come first served.
Its all I do as i have discovered an inefficiency which is slooowly evaorating...
Now,if I was making markets in longer dated options I would use it,despite its "flaws"..
I guess what I am asking you is if your model comes up with vastly different values that are outside the bid ask of the listed equity options??
And if so,would you blast away,delta hedge due to the perceived mispricing per your model??
To be fair, I don't have a model. I don't do these things, it's going to take research. My point is simply that because BS violates all the properties of good modeling, I have confidence that given the opportunity I could beat it using sound stat modeling if I could get someone to present me a use case with benchmarks to beat. And if I can't beat it, then well, won't that feel like a small vindication for a few of you.
If I was trading options, which I don't because I haven't finished my analysis yet, I would simply use them as a means to increase leverage and take short short side without having to sell anything. Simple, straight forward, easy to understand. Just the way I like it.
