My point was that the deal was structured in a way that practically ensured the share price would fall. To think otherwise, for facebook management or investors is to believe in hubris. I think it's telling and kind of odd that in Cuban's own defense of the deal, he's a sucker for having bought at the IPO price.
As an aside, high beta (volatility) stocks generally don't perform as well, long term, as do consistent growers with stable price action.
