Amazon is a high-flying stock that is great until it isn't. If they have a significant earning miss it other misstep, the stock will be punished.

It's a great company, but you need to understand the business and understand what Wall St expectations are.

Thanks for your quick and honest answer. I was over-weighting the effect of AWS as the cash cow for revenues (60% of profits) and forgot about how Wall Street punishes earning misses (the eternal treadmill of expectations).
