On CAPS, 94.3% of the 1,355 members who have rated Aflac believe the stock will outperform the S&P 500 going forward. These bulls include bartdz and bbluemz.

Just a few months ago, bartdz singled out the stock as a surefire income opportunity: "With an outstanding dividend payment record and no signs of that stopping, share price recovering with upside room remaining, plus a terrific advertising campaign here and a solid market base in Japan, to act as a counterweight -- what's not to like?"

In a pitch from last week, bbluemz assured Fools that Aflac is all it's quacked up to be:

Competitive advantage is their cutting edge technology, branding of the duck, distribution channels and diversity of product lines. Aflac's business generates excess capital with remarkably high rates of return given the high regulatory capital level requirements. The Company has continued to return this excess capital to their shareholders through share repurchases and increasing dividends. ... Time is on your side with a great undervalued company.
