In May of 2012 Kapitall interviewed Richard Rudden, Managing Partner of Target Rock Advisors. He highlighted the rapid increase of dollars invested in socially responsible firms and suggested utility stocks are a logical and profitable place for socially responsible investors. "Utilities are rarely considered candidates for the large and rapidly growing number of socially responsible investing funds," Rudden had said, “But we want to call attention to the industry for people looking for more income producing steady growth in their portfolio.” To that end, his firm creates unique sustainability utility indexes ranked by environmental stewardship, economic performance and societal contribution. Together their “triple bottom line” approach has led to some impressive index results with strong payouts, average earnings growth, and names that consistently grow or maintain their dividends. Target Rock's high-sustainability index, listed here returned an impressive average 16% 1-year return . In the lead is Sempra Energy (SRE) with a 37% 1-year return. The firm also ranks highest with the "triple bottom line" approach. 2013 Winners With its flagship index, the Target Rock Sustainable Utility Leaders Index (SULI), the advisory team focuses more on comparing sustainability leaders with non or lesser sustainability leaders.
