There is no disputing the fact of Facebook dominance in social media but its model of making money is far from proved to give it such a huge market value . The underwriters of the company are said to have massive amounts of shares worth billions which they have bought to hold the company's stock price above the IPO price of $38. The trading was marked by a number of glitches which is now being investigated by SEC. This has become a regular occurence reducing trust in the US capital market systems . A lot of the future earnings power is already built into the stock price of the company at $100 billion. It will take a lot of effort to get to the earnings level to justify the market price . In the fast changing technology landscape that is a huge risk . 3 years ago nobody would have questioned the dominance of Nokia and RIMM in the mobile space . But now these companies are fighting for survival. Stock picking is a game of probabilities and in the case of Facebook the current stock price does not justify the risk in buying it.
