NEW YORK (TheStreet) -Amazon's (AMZN) growth and valuation have provided much fodder for debate: Bears argue the valuation is unfathomable, while bulls talk about the bright future and continue to push the stock higher and higher.Personally, I see both sides. The stock price continues to go higher, even though profits continue to flatline. But, hey, that's the trend. Why short into that? I never understood that. The bearish rationale makes sense, and I can see why someone wouldn't buy the stock. But shorting it -- at least over a long period of time -- seems to be equivalent of stepping in front of a train. But the stock could be an excellent buy rnow, after it finally broke out of its short-term downward channel. As you can see on the image below, the stock was already favoring the downside going into earnings.
