Based on the aggregated intelligence of 125,000-plus investors participating in Motley Fool CAPS, the Fool's free investing community, Comcast (NASDAQ:CMCSA), which claims to be the nation's largest cable operator, has received a distressing two-star ranking. While one-star stocks have been the worst performers, our data has shown that two-star stocks still lag the market by a significant margin and should be approached with caution; conversely, highly-rated stocks have outperformed the S&P.

With that in mind, let's take a closer look at Comcast's business and see what CAPS investors are saying about the stock right now.

On CAPS, 51 of the 221 All-Star members who have rated Comcast -- 23% -- believe the stock will underperform the S&P 500. Among the bearish population are SideShowMel0329 and joshbk.

Last month, SideShowMel0329 described Comcast in not-so-glowing terms:

Poorly managed, poorly run, awful quality. I don't know of anyone who is happy with their Comcast connections. People are jumping ship to Verizon services by the thousands. The only reason Comcast is still in business is because it snatched up a great deal of market share earlier this decade when competition was scarce.

In a pitch from one week later, joshbk shares that bearish attitude:

How long can Comcast maintain its cable monopoly in various cities around America? As technology advances, it's becoming more feasible to have 1 cable company offering services in any given city. Current economic conditions are unlikely to affect demand for cable/internet service, but they will leave citizens wondering why their rates are high and why they lack of choices in cable providers. …

As consumer spending decreases, consumers will look to their politicians to examine costly local monopolistic regs. In general, recessions are the perfect time to shake things up, punishing inefficient companies and rewarding efficient ones.
