On CAPS, 27% of the 4,437 members who have rated Amazon believe the stock will underperform the S&P 500 going forward. These bears include All-Star killtheump, who is ranked in the top 6% of our community, and mistercube.

Just last week, killtheump wrote that the bear case all boiled down to price:

Don't get me wrong, [Amazon] is a great stock, and it's run by a visionary leader. Still, a P/E ratio of 80 is asking a lot. I wish I'd been invested during what's been a great year for [Amazon], and I'll be looking for an opportunity to climb aboard for the next run. Now is not the time, however.

In a pitch from one week earlier, mistercube also warned Fools about piling on Amazon:

[T]he story here has been the same for months: Valuation. We are fast approaching a triple-digit earnings multiple, and though the next positive report may correct it downward, we're still going to be talking about a pricey stock in January. …

I realize Amazon is diversifying beyond retail, has a killer proprietary product (though I still personally find the Kindle's long-term usefulness dubious), and just floats along on a river of greenbacks. But if you buy it today, you're not actually getting any of that money, and I reckon it's a long time before you do. This is a great story stock, easy to understand, with great name-recognition, and those are exactly the reasons it's oversaturated right now.
