On CAPS, 97% of the 1,151 members who have rated Medco believe the stock will outperform the S&P 500 going forward. These bulls include gweech and All-Star awesomestockdude, who is ranked in the top 2% of our community.

Earlier this month, gweech touched on the tailwinds working in Medco's favor: "A ton of baby boomers in need of generics and a ton of patents up in the next few years. Medco is a well run company."

In fact, Medco's three-year average return on equity (21%) clearly tops that of listed rivals Aetna (15.9%), Humana (17.6%), and UnitedHealth (16.8%).

CAPS All-Star awesomestockdude expanded on the outperform case last October:

There are several other growth drivers for MHS that should help increase revenue, grow margins, and put the business into different and growing areas:

Generics provide lower revenue compared to brand-name drugs but have much higher margins, which means more earnings. ...

Specialty Pharmacy
This part of their business is still not that significant compared to the PBM, but should continue to grow as they expand by creating new services that reduce drug cost and are more convenient. ...

This sector is still very small, but over the years I can easily see the idea of "personalized drugs" being the next big thing. ...

I bet over time as the baby boomers become older this service from MHS would seem extremely attractive, and we should see more customers come to MHS.
