On CAPS, 29% of the 5,596 members who have rated Dell believe the stock will underperform the S&P 500 going forward. These bears include ExtraValu and All-Star mevanzzz, who is ranked in the top 10% of our community.

Earlier this month, ExtraValu went directly to the bearish point: "I just don't see the appeal here. They have zero innovation and are getting squeezed from all sides. Tech is hurting right now there's no chance that Dell can outperform in an environment like this."

Despite the sales progress Dell seems to be making in its shift away from purely PCs toward the higher-return enterprise solutions space, a la HP and IBM, its margins have yet to expand in any exciting manner. While the consumer products division now accounts for less than 20% of Dell's sales, Foolish tech expert Anders Bylund noted last week that Dell needs to focus even more on becoming a "single-minded mastodon of the data center."

With Apple (Nasdaq: AAPL) and Acer right on its heels in the American PC market, completely letting go of the consumer seems to be the best thing for Dell's long-term turnaround.  

But even then, CAPS All-Star mevanzz leaves us with a top-down reason to stay away:

Dell will be unable to achieve analysts' expectations in their second half of the year. $0.30 and $0.32 EPS are going to be difficult for the company to reach in the 3rd and 4th quarters, respectively. Corporate IT infrastructure spending will be lighter in the second half of the year than expected. Hiring has not picked up, and so companies will need less IT equipment than expected.

This may be a broader trend. Analysts may need to revisit their earnings estimates across the board for the second half of 2010, if recent economic trends continue.

What do you think about Dell, or any other stock for that matter? If you want to retire rich, you need to protect your portfolio from any undue risk.
