I issued no "buy recommendation", but your posts are misleading and you are ignoring the positives on the company. One confirmed trend the last decade is that internet commerce and internet related businesses are being won by extremely large players ( eg GOOG, FB, AMZN; even MSFT has strengthened again ).
The late 1990s most internet related companies were severely overpriced and most went out of business. They had little or no market share and weren't profitable. What in fact actually happened in the years since is that profits arrived, but mostly for massive global monopolies in certain services. I don't fully understand how GOOG or FB make so much money from seemingly simple things, but they do. AMZN is showing signs of doing the same, but I'd certainly agree with you it's not a fully proven advantage yet. And a P/E of 200+ is a red flag when one is more of a fundamentals investor like myself. I just don't think it's wise to pronounce weakness in AMZN given all these factors and that earnings report, that was one of the biggest beats in recent history.
Shorting AMZN against trend and that last report is pure gamble at this point. Some gambles work out.
