On CAPS, 97% of the 1,777 members who have rated Exelon believe the stock will outperform the S&P 500 going forward. These bulls include AlpineFlower and tekennedy.

About two months ago, AlpineFlower tapped Exelon as a particularly timely bargain: "Nuclear took a hit with the Fukushima disaster, however this is still a long-term stock to invest in. Lots of value and great dividend."

Exelon even boasts a robust three-year average operating margin of 27.6%. That's clearly higher than that of listed competitors like AEP (19.5%), NextEra (18.4%), and PPL (19.8%).

CAPS member tekennedy elaborates on the bull case:

Exelon, as the largest provider of nuclear electricity generation, has a number of advantages other competitors don't have. Nuclear power has a lower cost than other types of generation and these operators have higher margins and higher returns on equity as a result. There are barriers for new competitors to build a nuclear plant as well because of regulatory issues, long build times for a nuclear plant, and high costs to build.

Secondly I think management here is top-notch as they have refused to overpay for acquisitions they have persued over the last decade. Growth will likely occur from expansions of capacity through current generators and from general commodity price expansion, but acquisitions could play a part as well. The dividend should represent a fair amount of future returns but I expect earnings growth and dividend growth to be high over the next decade.
