On CAPS, 20% of the 6,608 members who have rated Amazon believe the stock will underperform the S&P 500 going forward.

Just yesterday, one of those Fools, Valueeqanalyst, touched on the stock's seemingly unsustainable valuation:

Amazon can either meet revenue growth expectations or margin growth expectations but probably not both. The stock trades at a very, very high multiple (even factoring in the growth) given that at the end of the day it's a retailer. Just for context, [Wal-Mart] has [net income] margins of about 3%, that's where [Amazon] can hope to get to. ... It'll take time, but a few misses can really punish the stock. Intrinsic value is probably about half of the [current price].

Of course, that short pitch doesn't even come close to telling the entire story for Amazon. You're in luck though. The Fool's brand new premium report on Amazon tells all sides of the story for one of the most compelling and powerful internet companies in the world.
