Pursuing ESG Standards and Diversification
Blog post
July 27, 2017
Many of the world's largest institutional investors are integrating ESG standards into their investment strategies. But they face a challenge: Excluding every objectionable firm or selecting only ESG (environmental, social and governance) leaders can slash the number of acceptable stocks by half while foreclosing on opportunities for dialogue and engagement. How can institutions implement ESG principles without sacrificing diversification or abandoning efforts to improve corporate conduct?
One way is to increase the weightings of companies with strong ESG profiles, including those that show improved ESG ratings over the most recent 12 months, while minimizing exclusions to a core group of objectionable stocks. This approach can enable investment in a broad, diversified stock universe while allowing institutional investors to engage poor ESG performers.
The first challenge is establishing the core set of excluded stocks. After consulting large asset owners, we arrived at a consensus to exclude only the worst ESG performers, as defined by their involvement in controversial weapons (cluster munitions, landmines, biological and chemical weapons), and violations of international human-rights and environmental norms. The second challenge is weighting the remaining stocks toward companies that have a strong ESG profile or are improving their ESG performance.
Backtested performance of the MSCI ESG Universal Index, designed to represent such a strategy, produced a superior ESG profile to the index's parent ACWI index while retaining similar risk-return characteristics, with a 1% tracking error (the degree to which a portfolio's performance deviates from its parent index). As shown in the charts below, the ESG Universal Index narrowly outperformed the MSCI ACWI Index (which represents 46 developed and emerging markets) by an annual average of 10 basis points over a 7.5-year simulation period.1
Thus, targeting companies with stronger ESG profiles than their peers produced a result with similar risk-return characteristics as the parent index. Such approaches could help large asset owners seeking a more systematic way to integrate ESG considerations into their investment strategy.
