On CAPS, 96% of the 246 members who have rated Cal Water believe the stock will outperform the S&P 500 going forward. These bulls include sudspark and concealedweaponR.

This past spring, sudspark tapped Cal Water as a particularly solid income opportunity:

Extremely stable stock. Great pattern of increasing dividends. Easy 25% upside including dividends.

Over the next five years, in fact, Cal Water is expected to grow its bottom line at a solid rate of 9% annually. That's faster than other water utility plays like Aqua America (NYSE: WTR) (6%), American States Water (NYSE: AWR) (5.5%), and Sabesp (NYSE: SBS) (6%).

CAPS member concealedweaponR elaborates on the Cal Water bull case:

BORING. Slow steady growth in a simple company. Not a company people think about at all when they have their money in it. Even in the market crash no body worries about this one. Buy it, hold it, compound the dividends, go to sleep, forget about it.
