Money | Facebook Why Buying Facebook Stock Is for Suckers Do you really know what you're buying?

(AP Photo/Paul Sakuma) The investment world seems to be going gaga over the opportunity to buy shares of Facebook—or at least, the prospect that uber-wealthy Goldman Sachs clients can now buy shares of Facebook. But Duff McDonald of Fortune wouldn’t do it—and not just because he hasn’t got the requisite $2 million. His reasoning: Someone who knows more than I do is selling: The sale isn’t dilutive—it’s Facebook’s early investors selling their personal stakes. Why would they do that if this was the greatest investment in town? Goldman Sachs: Goldman doesn’t really think the company’s worth $50 billion, it’s angling to handle the lucrative IPO. FarmVille: It’s disturbing that Facebook’s big moneymaker seems to appeal to the lowest common denominator—a recipe for low margins. “You think they’re going to justify a $50 billion market capitalization through banner ads? Are you kidding me?” The secrecy thing: “Important question: Just what are Facebook’s numbers? Important answer: Who the hell knows?” And what we do know—that the company had $2 billion in revenue this year—makes the $50 billion figure look pretty ridiculous.
