Facebook's stock plunge highlights fears about future growth

Facebook's ongoing pains as a newly public company continued Friday as shares dropped to a new low following signs the company's growth is slowing.

Facebook's decline is dramatic. "It's going from bad to worse," says Fitzgibbon. "It's been a train wreck from the start."

The fallout from the first earnings call also shows Facebook may have been a victim of hype and inflated expectations, analysts say.
