How'd funds fare in 2020 when viewed through an ESG lens? We assign Globe Ratings, w/'High' (ie 5 globes) going to funds whose holdings court less ESG risk and vice versa for 'Low' (1 globe). Tldr: Funds w/higher ESG ratings beat their M* idx more often than those w/lower ratings

Given this, it's not too surprising that higher ESG-rated funds generated larger avg. excess returns (vs. M* cat. index) in 2020 than lower ESG-rated funds, meaning there was a better payoff to investing in funds that courted less ESG risk. That said, caveats apply...

1st caveat: When we look at success rates by 'intentionality' (ie, is strategy intentionally aiming to incorporate ESG, etc), we find success rates don't vary much by rating. In other words, success didn't depend as much on whether fund was actually *trying* to minimize ESG risk

Along those lines, there was a better payoff to minimizing ESG risk among non-intentional than intentional ESG funds. That is, there was a wider spread in the avg. excess return of higher- and lower-ESG rated non-intentional funds than there was among intentional funds. Nuanced.

Worth noting there are relatively few 'intentional' ESG funds. Of 4,000+ funds I examined, ~460 were classified 'Sustainable Investment--ESG Overall' as of 12/31/19, the starting point for the study. So, non-intentional funds drive the results.
