Over on CAPS, fully 489 of the 505 members who have rated LabCorp -- some 97% -- believe the stock will outperform the S&P 500 going forward. These bulls include All-Star healthcarevalue, who is ranked in the top 10% of our community, and athenamike.

Last month, LabCorp seemed to pass several of healthcarevalue's tests for value:

Price/earnings 14.65, Minimal to no long-term debt & low debt/equity of near zero, and focus on lab testing, both routine diagnosis testing and specialty testing services -- should prove to be a good niche market going forward.

In a pitch from two days later, athenamike conducted a follow-up:

LabCorp is building scale and increasing returns on capital over time -- what's not to like. Medical lab testing is growing, it's a relatively small medical expense, it can dramatically improve medical outcomes, and it is becoming an oligopoly between Quest Diagnostics and LabCorp. All this leads to me to predict 15% returns on equity and high growth for quite some time, which should turn into excellent returns over time.
