Hello all, As many if you know, Facebook's current market valuation is about 60-70bln dollars. Is this over valued, to say the least? I believe so. Let me explain: Facebook, who claims to have 500 million active users, only generated 800 million in revenues in 2010. While that may seems like alot, Facebook has spent billions on development of Facebook and are by far in the red. But because they are not a public company, we don't have view to that information. And at a 70bln dollar valuation, should Facebook have the same valuation as McDonalds? A valuation isn't just what the company is worth, but takes into consideration its future, it's physical assetts, government/laws, it's past financial performances, ability to change within the marketplace. We can assume that Facebook won't grow too much anymore, because of technological barriers throughout most of the world. So, let's just say that theoretically that 800 million REVENUE was PROFIT, which we know it's not, but at Facebook's current valuation of 70bln, it would take 87.5 years to have its total book value equal its market price/valuation. Unless Facebook starts selling your e-mails (oh wait), then I would suggest not to buy this stock when Facebook goes public. It's a "dotcom bubble" in itself and people WILL lose millions when they buy the stock. I promise. My honest opinion is it's 10bln dollars at the most.
