As bad as the declines have been, though, a view persists that the stock remains overvalued.
Monday's closing price of $34.03 implied a 24 percent annual growth rate for Facebook earnings over the next 10 years -- a rate that would rank above 90 percent of the companies in that industry.
Thomson Reuters Starmine, meanwhile, more conservatively estimates a 10.8 percent annual growth rate, which would value the stock at $9.59 a share, a 72 percent discount to its IPO price.
Similarly, the company's price-to-earnings ratio remains lofty, even after the selloff. The $34.03 price implies a forward P/E of 59, compared with Google's 13.3 forward price-to-earnings ratio (for a similar rate of growth).
