"The fact that the Facebook stock price has sunk below $20 has hurt a lot of small investors who bough the stock at $40 or so, thinking they could strike it rich," she said. "Other than that, it is just the market establishing the true value of Facebook, which at $20 is perhaps about fairly evaluated... Just because the stock price has sunk a lot, doesn't mean Facebook is in trouble. It doesn't really directly affect their operations. But it does show that a lot of people now think the dream of making trillions with social is over. Great expectations meet reality."
