good point re hedging risk an, but then again, the whole idea of hedging losers is false imho. i dont think they really do hedge that much if at all.
reasons people hedge are to either:
lock in a price
flatten vol
get more leverage
none of these as far as i can see are really appropriate to the sb model. maybe flatten vol, but with 90% of your customers positions going your way, whats the point.
going back to the casino analogy, or better yet a high street book maker, they will often lay off a large bet amongst other bookies, but the majority of customer positions they will not tamper with, simply cos as every bookie knows, the average gambler is on a hiding to nothing.
simple.
