Why ESG Investors Should Look Beyond the Obvious Choices

Companies that are on course to overcome ESG controversies deserve closer attention from investors.

Sustainable equity funds tend to shy away from sectors and companies that are deemed to be controversial. Yet by targeting challenged sectors with room for improvement and overlooked companies that enable positive change, we think investors can access more diverse sources of return potential in portfolios focused on environmental, social and governance (ESG) issues.

For many ESG-focused investors, buying shares of companies that are good actors seems a natural choice. After all, shouldn’t we reward companies with low CO2 emissions, positive social policies and good governance? By doing so, bad actors will be incentivized to behave better.

When executed properly and backed by a coherent engagement agenda, this strategy is an effective way to support ESG goals and source equity returns. But there’s another road to ESG investing that is much less traveled—and offers access to an entirely different set of companies.

ESG Upgrades Help Support Outperformance

Despite conventional wisdom, we think companies with lower ESG ratings deserve closer attention. That’s because many companies with high ESG ratings can’t realistically improve much more, while lower-rated companies have more room for improvement, which can also support returns.

Our research shows that shares of companies receiving an ESG rating upgrade outperformed the MSCI All Country World Index (ACWI) by 0.36% over the subsequent 12-month period, while those that were downgraded underperformed by 1.33% (Display). In other words, companies likely to see an increase in their ESG rating can be a source of return potential—for investors who can find them.
