Over on CAPS, fully 296 of the 1,057 All-Star members who have rated Amazon -- some 28% -- believe the stock will underperform the S&P 500 going forward. These bulls include bobbyabull and mysoftballcoach, both of whom are ranked in the top 20% of our community.

Last month, bobbyabull wrote that Amazon:

... is a great concept that everyone uses from time to time, but it trades at 40X earnings with a PEG above 2.00 (2/5/09) ... At some point, there has to be some profit taking or a slightly disappointing quarter. Amazon trades like a skyrocketing small-cap, which it isn't.

In a pitch from a few weeks earlier, mysoftballcoach also tapped Amazon as a super company trading at a somewhat scary price:

I hate to make this underperform call on Amazon. I love this company and I love their business model. They have emerged as a true powerhouse in the retail industry. HOWEVER, I just can't help believe that consumer spending is falling off a cliff and that this trend will remain for many more months. So even though [Amazon] is among the very best companies, they too will be affected by the economy. As such, I don't believe the stock will be able to maintain the high P/E ratio. Other GREAT companies such as [Google], [Apple], and [Akamai (NASDAQ:AKAM)] have seen contraction in their P/E ratios and I believe it's just a matter of time before the contraction also hits [Amazon].
