Drawing conclusions of a company's performance given a stock price change is a classical mistake. The share price change only says if the announced figures were in accordance to the market's expectations and has nothing to do with the level of those figures. If amazon's stock went up is because the market expected its profits were gonna be worse than they actually were. It doesn't mean the market thinks amazon is awesome.
