On CAPS, 45% of the 44 All-Star members who have rated WebMD believe the stock will underperform the S&P 500 going forward. These bears include Caligiuri and BSHumphreyII, both of whom are ranked in the top 10% of our community.

Two weeks ago, Caligiuri outlined some of the health risks associated with the stock:

If Google comes out with a similar website to WebMD instead of purchasing it, WebMD will no doubt receive less visitors. I guess you could say WebMD is a name brand, but so is Google.

I think a lot of growth and success is projected into the stock price, and I don't think it's going to happen. My bet is that Web MD gets bought for much less than it's selling for though.

In a pitch from just yesterday, BSHumphrey concurs with that bearish diagnosis:

WebMD's high P/E ratio just isn't justified by the numbers. Other than a slight spike last quarter (possibly attributable to the H1N1 scare), their earnings seem to be in general decline.

A lot of other sites, such as the Mayo Clinic's, provide the same service, and, as another Fool mentioned here, it's probably only a matter of time before a heavy hitter like Google gets into the game. Whatever "moat" this company had is quickly crumbling, and all that's left of it is its brand.

The brand simply isn't worth WebMD's $2.2 billion market cap.
