You actually don't need to own the stock to sell it. You can borrow it from a broker.

Don't do this now, because the big slide is likely to have already happened, and you'd be hard pressed to make money. After you borrow and sell the stock, you have to buy it back at a low enough price to pay the broker their commission on top of the principal for the stock, and make some money too.

I agree with your sentiment, though. Less Fakebook = more freedom.
