Thanks for this useful information.It is being arbed and it doesn't get considerably out of line. Not anymore anyway. The party has been over for a while now.
We both speak to someone who started his firm with the proceeds from that Vix craziness - some great stories.You should've seen the things going on in '07-'08
Roger.IMO, the few dislocations that still occur are largely due to capacity constraints. There is no fungible spot so any trader/shop worth a damn will cap their size at a certain level. No one would trade a 15 cent dislocation flat and end up holding 2000 flies. Then August 24th comes around and you give up 30 cents just in slippage and thats assuming you are offsetting against the trend. Try closing that much short vol into a spiking vix and tell me how the algos treat you when the market goes 10up.
