ESG Factor Returns: 2022 in Review
- ESG factor returns were lower in 2022 than the previous five years but remained positive.
- Within the MSCI ACWI Investable Market Index (IMI), companies in the top ESG quintile outperformed those in the bottom quintile consistently over 1-, 3- and 5-year periods.
- Over longer time periods, the ESG factor has consistently shown positive or neutral performance across sectors, although results have been more mixed over shorter periods.
ESG factor return in detail
Based on the pure ESG factor performance within the MSCI Global Equity and MSCI USA Equity Factor Models,3 returns in 2022 were lower than during the previous five years but still positive (see exhibit below).

We also assessed factor performance by sorting the ESG scores of constituents of the MSCI ACWI IMI in quintiles, from the bottom scoring constituents (quintile 1) to the top scoring (quintile 5).4 We observed that the top quintile companies outperformed those in the bottom quintile over 1-, 3- and 5-year time horizons. The same analysis for constituents of the MSCI World ex USA IMI, MSCI USA IMI and MSCI Emerging Markets IMI indexes yielded similar observations, although we found some variations for emerging markets over the 1-year horizon.5

A look at sector returns
Global equity markets, as represented by the MSCI ACWI IMI, saw a strong sector rotation, as shown in the exhibit below. Energy was the best-performing sector, while the boom sectors of previous years — information technology and communication services — were the worst-performers.

To get a clearer understanding of the impact of ESG on returns, we looked at its sector-performance contribution.6 Companies in the top ESG quintile outperformed those in the bottom ESG quintile for every sector over the 5-year horizon. It was a similar picture over the 3-year horizon too, with the exceptions being the energy and materials sectors. The picture was mixed for the 1-year horizon (2022), with outperformance of companies in the top ESG quintile observed in only six of the 11 sectors.

Our findings highlight that over longer periods of time, the ESG factor consistently showed positive or neutral performance across sectors, while over shorter periods of time results were more mixed, despite a positive performance at the global level.
The significance of sector, time and region
Based on our analysis, ESG factor performance remained positive in 2022, but was slightly below the level seen in previous years and not equally distributed across sectors and regions. This suggests that time horizons as well as specific sectors and regions may be significant in assessing the return characteristics of ESG portfolios.
