On CAPS, 97% of the 656 members who have rated LabCorp believe the stock will outperform the S&P 500 going forward. These bulls include 94impala and DrTechnical.

Earlier this year, 94impala touched on the healthy trends working in LabCorp's favor:

Low cost leader. Check the population/age curve and watch what happens with health care reform. Testing demand will go up and LH is my pick

LabCorp even sports a solid three-year average net margin of 10.8%. That's higher than that of rivals Bio-Reference (5.9%) and Quest Diagnostics (8.3%).

CAPS member DrTechnical elaborates on the LabCorp bull case:

The company is concentrating efforts to develop (or acquire) technology for genetic testing, with its associated higher margins than regular routine blood tests. Coupled with its existing DNA testing facility, plus the recently acquired genetics testing arm of Genzyme, LabCorp is well-positioned for the testing needs of the future. In addition, its efforts to automate the testing process (which is currently very labor-intensive) will help keep costs low to remain competitive.
