The following video is from this week's Motley Fool Money radio show, with Chris Hill, Ron Gross, James Early, and Joe Magyer. Shares of Facebook fell nearly 12% on Friday in the wake of the company's first-ever earnings report. Even with the sell-off, shares are trading at a much higher multiple than stocks like Google and LinkedIn. In this segment, the guys analyze the challenges facing Facebook, including the struggle it faces in making significant revenue from its mobile platform. CEO Mark Zuckerberg said on Facebook's conference call with analysts that the company is investing heavily in mobile. Can Facebook make a good return on that investment soon enough to satisfy shareholders or is it running out of time?

While shares of Apple fell slightly this week, they aren't trading at a steep discount.
