Facebook 4Q 2012: Despite Surpassing Expectations, Facebook's Stock Slips

NEW YORK (AP) -- Facebook delivered fourth-quarter results above Wall Street's expectations Wednesday and said its mobile ad revenue -- a closely watched figure -- is growing. "Everything was slightly better than expected," said Wedbush Securities analyst Michael Pachter. Facebook's stock increased 16 cents to $31.40 in after-hours trading after briefly dipping lower just after the release of the results.
