Zusammenfassung
Does socially responsible investing (SRI) lead to inferior or superior portfolio performance? This study focused on the concept of "eco-efficiency," which can be thought of as the economic value a company creates relative to the waste it generates, and found that SRI produced superior performance. Based on Innovest Strategic Value Advisors' corporate eco-efficiency scores, the study constructed and evaluated two equity portfolios that differed in eco-efficiency. The high-ranked portfolio provided substantially higher average returns than its low-ranked counterpart over the 1995-2003 period. This performance differential could not be explained by differences in market sensitivity, investment style, or industry-specific factors. Moreover, the results remained significant for all levels of transaction costs, suggesting that the incremental benefits of SRI can be substantial.
