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.

What do you think about Amazon, or any other stock for that matter? If you want to retire rich, you need to protect your portfolio from any undue risk. Staying away from dangerous stocks is crucial to securing your financial future, and on Motley Fool CAPS, thousands of investors are working every day to flag them. CAPS is 100% free, so get started!
