On CAPS, 44% of the 63 members who have rated Advisory Board believe the stock will underperform the S&P 500 going forward. These bears include All-Stars BuffettJunior1 and TSIF, both of whom are ranked in the top 10% of our community.

Just last month, BuffettJunior1 touched on Advisory Board's seemingly unsustainable valuation: "Unless this company can grow at over 50% per year over the next 10 years, I don't think its worth over a billion dollars, as its market cap suggests."

In fact, Advisory Board sports a particularly lofty P/E of 65. That represents a clear premium to competitors like Accenture (17), Cerner (38), and McKesson (18).

While Advisory Board's stock price has remained resilient, CAPS All-Star TSIF says he's cautiously sticking to the underperform call:

My theory was that with the high valuation that it would certainly disappoint at some point. The health care industry has been taking hits as the government clamps down. A company that specializes in advice would seem to be a luxury that it's customers couldn't afford, but the crunch apparently gives The Advisory Board Company a much needed value add. ...

Growth does appear to be slowing. ... Margins are not supporting growth.
