MSCI ESG Ratings in Global Equity Markets: A Long-Term Performance Review
Research Paper
March 1, 2024
Preview
In this paper, we review the financial performance of MSCI ESG Ratings in global (MSCI ACWI Index) and developed (MSCI World Index) markets over the course of their history of 11 and 17 years, respectively.
A key difference between MSCI ESG Ratings and traditional market-risk factors such as value or momentum is the fact that MSCI ESG Ratings assess corporate risk rather than market risk. Our study was therefore based on both a fundamental performance assessment (how differences in ESG ratings were associated with differences in earnings and profitability) and a stock-price performance assessment. This is important to understand to what extent (if observed) better corporate-earnings fundamentals were transmitted into better market performance, which we called the "transmission channel."
Using a standard quintile analysis on MSCI ESG scores (controlled for sectors, regions and company size), we found that companies with higher MSCI ESG Ratings outperformed their lower-rated counterparts across both the MSCI ACWI Index and the MSCI World Index over the study periods.

How ESG Risk Management Can Impact Security Risk
Following extensive research showing an improvement in risk-adjusted returns for companies with higher ESG ratings, we look beyond what a company's ESG issues were to how that company dealt with them — and the impact that had on stock-specific risk.
Illuminating the Relationship Between ESG and Performance
Time horizons are key to understanding the impact of environmental, social and governance on stock returns. This paper, which was published in Investments & Wealth Monitor, illustrates the relative importance of event risk vs. erosion risks over time.
MSCI ESG Ratings
ESG Rating is designed to measure a company's resilience to long-term, industry material environmental, social and governance (ESG) risks.
