Flow‐Driven ESG Returns
Abstract
I show that the recent returns to environmental, social, and governance (ESG) investing are strongly driven by price impact from flows toward ESG portfolios. Using data on trades, I estimate the market's ability to accommodate ESG flows, which is given by the elasticity of substitution between ESG and other stocks. I show that every dollar flowing toward a representative ESG portfolio increases the market value of ESG stocks by $0.8. The growing institutional flows into the ESG portfolio are the main driver of ESG returns and have caused an annual flow‐driven return of 1.9%. In the absence of flows, ESG stocks would not have outperformed the market from 2012 to 2023.
