Those outcomes are likely. Although it's also possible that:

* next-quarter results are "less bad" than expected, and the large band of short sellers have to start buying to cover

* insiders feel that the stock is unfairly priced and are willing to hold on until it improves

* Facebook's IPO is a roaring success and generates a rising tide for all internet stocks

I think the first one has the most chance of happening. The stock is heavily shorted right now, any news that's not negative has the chance of sparking a rally.
