8. Facebook

Facebook raised more than $100 billion in one of the most anticipated initial public offerings in tech history. Shares began the day trading at $38 and reached a high of $45, only to drift back to their opening levels.

And then, to the shock and disappointment of investors, Facebook shares went into an extended free fall, hitting a low of $17.73 in September and triggering class action lawsuits. Questions swirled about the viability of Facebook's premium advertising model, and analysts wondered if the company would ever be able to figure out how to make money from mobile ads.
