On CAPS, 98% of the 691 members who have rated Genoptix believe the stock will outperform the S&P 500 going forward. These bulls include All-Star TheGrtGdOM, who is ranked in the top 15% of our community, and KMillionaire.

Late last year, TheGrtGdOM brought Genoptix's improving price to our community's attention:

Recovering from a very significantly excessive sell-off. It is still in the right place at the right time as health care reform will equal more people getting health care they need. When a stock is half of what it recently was without reason to believe anything different about the company's long term prospects, then it is a good time to buy.

Despite a soaring price over the past three months, Genoptix shares are still off 50% from their 52-week highs set in late April. Currently, Genoptix trades at an almost unbelievably low EV/EBITDA of 4.3, representing a clear discount to rivals Bio-Reference Labs (11.1), Genzyme (25.6), and LabCorp (9.1).

CAPS member KMillionaire is cautiously bullish:

This is a speculative play on my part. Their earnings growth is consistent with the idea that this is a potentially great growth stock. I wonder if they can keep that up, though. The company lowered their guidance and the price plummeted -- why does the share price get so shaken up by a little bad news? Risky; speculative.

Nonetheless, investor sentiment seems to be high, and it is priced cheap. That's about all one needs to know, for a stock like this. There is money to be made ... just be careful.
