Over on CAPS, 479 of the 502 members who have rated Quest Diagnostics -- some 95% -- believe the stock will outperform the S&P 500 going forward. These bulls include paintjockey and samhanlj.

In December, paintjockey came at Quest from a consumer perspective: "Growth is slow but steady. I use this service as a patient. Neither too pricy or cheap on service. Product is stable with elderly population growing, services a plus for medical community."

In a pitch from late last month, samhanlj expands on the unfortunately real trend working in the industry's favor:

A sure thing coming up right behind death and taxes: illness. As one of the biggest lab/diagnostic services in the country, Quest has solid earnings and dividends and an 8% NET profit margin. Not too shabby. Having said all this, I'd also have to recommend their biggest competitor, [LabCorp], whose financials look even stronger.
