Investors used to the letter-based system used to rate bonds will likely appreciate the new approach to ESG fund evaluations unveiled by a major research and data provider. In an announcement last week, MSCI revealed that it had added environmental, social, and governance ratings to 32,000 of its funds and ETFs in a bid to "boost investor transparency," reported ThinkAdvisor. The system scores funds on a scale from AAA (leader) to (CCC) laggard. "The MSCI ESG Fund Ratings are designed to provide investors with greater transparency to better understand the ESG characteristics of fund and ETF components of their portfolios," MSCI head of ESG Remy Briand said in a statement.
