Goog is fairly valued when compared to Yhoo. Goog's float is 173 million, Yhoo has 1.24 billion, so Goog is about fairly priced where it is. I think $300 is stretching it's valuation, and let's not forget that Yhoo was $11 or so last year. Stock prices can fluctuate; stock is not really worth anything perse, a point to always remember. Goog could go to $300, it could also drop down to $40 in the next 6 months, and it would not surprise me, in fact, if the Nasdaq runs into trouble, I think Goog could get massacred. Remember, there are a lot of 25 year olds that work there with lots of stock, and when Goog finally drops, it cold get pretty ugly.
