Can you may have your cake and eat it too?
The ongoing debate about environmental, social, and governance (ESG) investing typically seems like a rehash of that age-old rhetorical query.
Proponents of ESG information consider it might assist traders higher perceive the dangers and alternatives corporations face and should even provide alpha technology potential. Then again, skeptics suppose ESG standards restrict the universe of accessible shares and that such restrictions are sure to negatively influence returns.
To return to our metaphor, having the ESG cake means producing sturdy funding efficiency, whereas consuming it too implies doing good from an ESG perspective.
So which is it? Can traders have all of it?
To reply this, we analyzed Refinitiv’s ESG database, which covers greater than 7,000 public corporations throughout the globe. Refinitiv generates ESG scores for every agency primarily based on 178 information factors. Corporations are ranked on a 100-point scale relative to their friends, with a composite ESG rating in addition to separate class scores for atmosphere, social, and governance, individually. The upper the rating, the higher the ESG rating.
We divided the historic ESG rankings of all S&P 500 companies into 4 classes: These with scores of 76 or above are labeled “Glorious”; between 51 and 75 are “Good”; between 26 and 50 are “Truthful”; and 25 and beneath are “Poor.”

The development is evident: S&P 500 corporations have improved their ESG metrics over time — in all probability as a result of they acknowledge the growing significance of such scores and have taken steps to spice up them.
ESG Scores and Efficiency
So do corporations with excessive ESG rankings outperform their lower-ranked counterparts?
For perception on this, we created a Excessive ESG Portfolio composed of S&P 500 corporations that rating above the median and a Low ESG Portfolio made up of companies that price beneath it.
We constructed these portfolios on a month-to-month foundation, from January 2008 to December 2018, utilizing the ESG rating of the businesses. We then measured every portfolio’s returns over the following month, repeating the method for 132 months. We discovered that the Excessive ESG Portfolio outperformed the Low ESG Portfolio by 16 foundation factors (bps) per 12 months.
Efficiency of S&P 500 Excessive and Low ESG Portfolios
|Excessive ESG Portfolio||7.34%|
|Low ESG Portfolio||7.18%|
The geometric imply return of the Excessive ESG Portfolio exceeds that of the Low ESG Portfolio though the previous’s arithmetic common return is decrease.
Efficiency and Volatility of S&P 500 Excessive and Low ESG Portfolios
|Arithmetic Imply Return||Volatility (Annualized Normal Deviation)||Geometric Imply Return|
|Low ESG Portfolio||8.32%||16.38%||7.18%|
This counterintuitive consequence could be attributed to the distinction in volatility. The Excessive ESG Portfolio had a lot much less, so its returns compounded higher than these of the Low ESG Portfolio.
Over the long term, the cumulative efficiency of the 2 ESG portfolios is kind of related. We explore these and related results in much more granular detail in a longer companion piece.

Do Excessive ESG Rating Equal Increased High quality?
Does the decrease volatility of the Excessive ESG Portfolio point out larger high quality?
There’s certainly a constructive correlation. We regarded on the monthly payoffs of the Quality factor relative to our two portfolios and located a 0.41 correlation between the issue and the worth added by the Excessive ESG Portfolio in comparison with the Low ESG Portfolio. Additional testing of the Quality factor suggests an association of high ESG scores with higher quality.
Anecdotally, the Excessive ESG Portfolio provides worth extra usually throughout inventory market declines. The correlation between inventory market returns and the worth added by the Excessive ESG Portfolio over the Low ESG Portfolio is –0.27. That is statistically vital, with a t-statistic of three.16. The phenomenon was most pronounced throughout the international monetary disaster (GFC) in 2008 and the sharp restoration of 2009.

|2008 Return||2009 Return||Cumulative Return|
|Excessive ESG Portfolio||–35.63%||24.78%||–19.68%|
|Low ESG Portfolio||–42.15%||34.18%||–22.37%|
Addressing Some Frequent Considerations about ESG Investing
However what about ESG screens? By decreasing the variety of investable companies, do they act as a drag on efficiency?
The Excessive ESG Portfolio’s investable universe was 26% smaller as measured by market capitalization because of the above-the-median ESG rating requirement. That’s a big discount. But the Excessive ESG Portfolio nonetheless carried out nicely.
So, at a sensible degree, the idea that shrinking the choice of potential shares primarily based on ESG standards will result in decrease returns shouldn’t be supported by the historic information.
Furthermore, energetic traders can incorporate ESG info in a holistic method moderately than mechanically screening companies out. This could render the priority a moot level for many traders.
As ESG investing grows extra standard, traders are proper to query whether or not it may be completed with out sacrificing returns. Our evaluation reveals that it might.
- ESG investing, even in a rudimentary, mechanical kind, has generated returns which might be extremely aggressive relative to the benchmark.
- Corporations with excessive ESG scores show decrease volatility and presumably larger high quality.
Moreover, primarily based on our expertise managing inventory portfolios for greater than 20 years, we consider energetic traders can use ESG information to higher gauge firm high quality and apply that info, together with different related information, to make improved funding selections.
The ESG debate shouldn’t be a alternative between having your cake and consuming it too. Quite, ESG information is the icing on the cake: When ready and introduced nicely, it enhances each the having and the consuming.
