Hello Boys and Girls,I've just started looking into this too.I agree, a bit of empirical analysis should give you reasonable option pricing via BS and vol smiles.But I'm not intersted in options (yet).I'm thinking about risk managing books of the underlying, so the fat tails are of concern to me.If there were a liquid options market, I could get an implied distribution. But there isn't.So is there a formal/justifiable/well used tweak to the normal distribution to build in kurtosis?-- OR --Is there a well understood distribution that looks like a highly kurtotic normal dist that I could try to fit?Thanks everyone...
