I will not buy this but on the other hand it is no AAPL style mania either. In the last few yrs there were three times when people went a bit crazy. AAPL, gold (+ silver) and oil. Maybe also GOOG. Now here - this company is the future. And that is impossible ofcourse. Trouble is people are not that excited about it so the blowoff when it comes - there is no way to predict where and when.
I am beginning to like MSFT a bit. I see people are selling big and it is really lets face it a sluggish piece of #$%$. That is ofcourse always a good thing.
My favorite tactic is ofcourse to do nothing and AMZN fits the bill.
