Amr Awadallah: 22% sequential growth for a $1919M Q4 is still very impressive, but it missed the expectations and it certainly does not justify the $500 to $600 stock price targets that some analysts are setting. To put things in perspective, Microsoft with a marketcap of $300B did $11B in sales last quarter, that is almost double what Google made for the whole year, so how can Google get a marketcap of $150B (at $500 price target). I think Greenspan had a word for this, let me try to remember, ah, he called it “irrational exuberance”.
