Over on CAPS, fully 489 of the 535 members who have rated Humana -- some 91% -- believe the stock will outperform the S&P 500 going forward. These bulls include stover2000 and All-Star mrindependent, who is ranked in the top 4% of our community.

Late last month, stover2000 tapped the stock as a particularly healthy opportunity: "Large amount of cash, low P/E ratio based on over exaggerated fears due to concerns about health care financing."

In a more recent pitch, mrindependent also feels Humana's risks are more than priced in:

I am generally avoiding health care insurers due to the uncertainty created by health care reform, but this stock is such a good value that I think it is worth buying. [Humana] appeared on my favorite large cap stock screen today. The screen looks for the 25 S&P 500 stocks that have the lowest ratio of P/E to ROE. ... Besides passing my screen, I feel good about this pick because its forward P/E is only 6. The company is selling for 1.2 times book value.
