Some analysts are already talking about this sell of as a good buying opportunity. Honestly I dont know what to make of that. Overall as a company Google is damn good and no one can deny that, but whether the stock is over-priced or not thats a different thing. Its already 7% down in the after hours. Whether this is the start of a big sell of, I guess we will had to wait and see. But anyways, Google will be down tomorrow.
