When the market crashes, people will eventually flock to the stronger stocks. Check out Google's cash position and their growth over the past 3 quarters. Google made 15 Billion in profit, and is expected to make 20 Billion by next year. That at current prices comes out to a P/E of about 20, unheard of for those that think, Google is a false bubble. 900 may be cheap for a 20 P/E stock full of cash.
Look at their $1.8 billion in accounts receivable -- a nice way for them to pump-up earnings, in the short-term, is to book earnings before they are actually paid.
Of course, the future becomes less profitable, but the GOOG insiders don't care about the future; they just want to sell their BILLIONS worth of stock and laugh at the sucker public shareholders for the rest of their retirement!
