I am torn on this one. Rumored to open at like $45 a share.
An insanely large audience (845 million people) that they have just scratched the surface of beginning to monetize. Made a billion dollars last year in profits on 3.7 billion in revenues. 85% of revenues on ads, which they aren't really selling to many large companies. 12% on the crap people buy for the online games they host.
Facing massive competition from Google, Apple, Twitter, and Amazon though. By FB's own admission, they have nothing to spend the money on that they generate from the IPO. And no one clicks on their ads - which to this point they haven't been great at selling.
This one's a tough call. With that massive audience, my guess is that Facebook credits and FarmVille props can only get em so far, the super competitive online ad environment prevents ad sales from continuing to climb at their current rate ... and the stock suffers.
Then a year or two from now FB jumps into bed with a major retailer and starts selling everything and anything Amazon.com style.
