"A new MSCI study of ESG ratings finds they have a similar impact on share prices as do credit ratings."

[COMMENTARY]Though to me the findings are unsurprising, this is the first study to demonstrate that ESG ratings have a similar impact to credit ratings on a company’s stock price. This finding will no doubt be challenged, but comes at a time when investors everywhere are looking at the inclusion of ESG criteria in their investment research. It bodes well for the mainstreaming of ESG!
