They discover that after factor-adjusting the returns and risks of ESG and non-ESG stocks, portfolios of ESG stocks with positive alpha had return-to-risk features comparable to those of portfolios of non-ESG stocks with positive alpha. Portfolios of ESG stocks without statistically significant alpha displayed lower residual volatility than portfolios of non-ESG stocks without statistically significant alpha. The authors suggest that portfolio managers should focus on factor-adjusting their ESG portfolios to match non-ESG portfolios.TOPICS: ESG investing, equity portfolio management, portfolio management/multi-asset allocation ER -
