Has Facebook's (FB -1.4%) big rally finally run out of steam? Shares are now lower in spite of a Deutsche upgrade and a bullish note from Oppenheimer's Jason Helfstein. Helfstein claims new comScore data indicates the pace of Facebook's U.S. PC traffic decline (due in large part to mobile cannibalization) is slowing, and that the ROI for FBX Exchange ads is 2x that of regular Marketplace ads. Facebook, which reports on Jan. 30, is trading at 48x 2013E EPS.
