NEW YORK (TheStreet) -- For Amazon (AMZN) investors, the run higher has been nothing short of a storybook romance.

So far, Amazon shares have encountered only small bumps on the way. It's easy to see why so many investors have fallen under the spell that valuations don't apply with Amazon. Even after

How can anyone believe Amazon's cloud services will be anything other than a race to the bottom of profitability when Microsoft and Google are stepping up aggressiveness and lowering prices to take away market share from Amazon?

Clearly, Rackspace is more vulnerable to competition in cloud computing compared with Amazon; however, reduced vulnerability isn't tantamount to invincibility, even if Amazon has been treated like royalty in the past.

Investors should pay close attention to revenue, income and margins. If Apple's investors are justified in their disquiet for margins, Amazon's investors should be in full blown consternation.

Amazon's permabulls maintain that the company is building the infrastructure needed to increase profitability. That may be true; I buy into the argument right up to the point of profitability, at least on a per share basis. Sure overall profits may increase slightly, but will that actually be enough to make Amazon a good investment? I think not.

Amazon continues to allocate greater and greater amounts of money for relatively small gains in profit. It's not an altogether failing strategy, after all it has effectively kept investors optimistic to the point of driving up the forward P/E ratio to triple digits. At some point, the scale of operations becomes so gigantic that a meaningful increase in revenue is no longer a viable option.

It's simply not as easy for Amazon to double revenue again at the current scale as it was when Amazon's revenue was half the magnitude it is presently. Amazon's real hope for a fairy-tale ending depends on expanding margins and profitability. Unfortunately, the magic Amazon needs is hard to find outside of children's books.

Amazon sells more digital books than physical books. This should concern investors to no end. Because Amazon doesn't own content and is only a reseller, what will prevent margin-compression in digital sales distribution? Publishers including

already have the ability to distribute content to consumers directly. At a minimum, Amazon has little pricing power, and the risk of falling market share and margins is more likely a matter of when, not if.

Amazon faces competition in digital content delivery from every possible direction. The company's world-class distribution warehouse network may enjoy economies of scale and efficiency over other online retailers, but in the world of digital downloads, other competitors enjoy superior demographics in, for example, niche book sales with little barrier to entry. In short, you can forget about margin and profit growth in Amazon's large digital-product revenue stream.

Don't be the last one to figure this out, or you may pay a steep price for your education.
