Serious question: how could anyone ever think AMZN could crash with so much love and support?
All the "love" tied to one metric - sales growth. When sales growth wanes love will wain - happens to every stock in the market (mind you could happen earlier in amzn's case because of outsized run on misalligned investment). Right now they are look at top line growth of 20-35% so out performing better than market. Watershed moment coming soon for amzn as competition is getting more fierce this Q and will only see market share losses in 2013.
I think the enigma on that sales growth is that while AMZN has grown that, earnings decreased to capture that sales growth: The bullish theme by now that scale sales would drop to the bottom line and it just hasn't happened. In other words, WS continues to reward AMZN giving things away. Monetizing sales hasn't not proved to be as easy as anlaysts promotoed it to be.
