 buy these export restrictions and they've had to develop other kinds of chips for the chinese market as a result that will not change so i'm trying to figure out why nvidia is rallying 10 today the second thing when a three trillion dollar stock is rallying 10 it makes you kind of nervous volatility begets more volatility and so you get a little bit nervous on this and the other piece is look it might be all well and good that you can sell these chips to china anyways
