Why It's Time to Take ESG Investing Seriously

Your article was successfully shared with the contacts you provided.

August brought one of the most seismic shifts in capitalism’s history when nearly 200 CEOs of America’s largest companies, collectively known as the “Business Roundtable,” agreed to redefine the central purpose of the corporation.

No longer, the Business Roundtable declared, will the focus of the corporation be to maximize ­shareholder profits at any expense. Rather, the new central purpose of the corporation is to focus on delivering value to multiple social stakeholders — including ­employees, consumers and communities.

Why should advisors care? Because this new wave of social responsibility has come to Wall Street not by way of regulators or politicians, but from the millions of everyday investors who, through the allocation of their retirement savings, are now applying bone-crushing pressure to the world’s largest and most powerful multinationals to clean up their act.

This trend is fueled by three developments. First, today’s investors are more educated and better informed than at any time in history, which has led to a growing awareness of both the plethora and seriousness of the issues confronting society.

In the age of social media, companies who commit environmental atrocities or engage in abusive labor practices can be mercilessly punished by consumers (via boycotts that hurt revenue) and investors (who drive up the cost of capital for offenders).

Second, there is growing consensus that government action by itself is a necessary but insufficient solution to some of society’s most pressing challenges, such as climate change and social inequality.

Finally, seismic demographic and economic shifts have brought more women and millennials, who generally tend to be more socially conscious investors, into global capital markets.

What’s in a Name?

Don’t be confused. The key word is “investing”; this is not about philanthropy. Regardless of the label, all of these approaches are ultimately about seeking a positive financial return while bringing about positive change in some way.

Socially Responsible Investing

Socially responsible investing typically refers to constructing portfolios using “negative screens” to exclude firms or sectors involved in activities investors deem to be unacceptable or controversial, such as excluding firms that sell weapons.

Environmental, Social & Governance Investing

ESG investing, while related to SRI, is materially different. ESG investing focuses on investing in companies with high ESG scores relative to their peers.

Subsequently, ESG investing doesn’t necessarily exclude “bad actors”; it focuses on firms with high sustainability ratings relative to their peers. It’s an approach that subsequently focuses on “best-in-class” firms but doesn’t explicitly exclude any firm or industry.

Impact Investing

Impact investing essentially is a hybrid taking from SRI and ESG investing. It goes further by focusing on solving specific social or environmental problems in two ways. First, it explicitly focuses on those companies with the best ESG scores, and second, it typically excludes companies engaged in undesirable activities.

Modern Portfolio Theory suggests that limiting the investing universe results in the construction of a less risk-efficient portfolio. However, there is now a considerable amount of academic evidence that proves SRI — in all its forms —does not reduce performance.

There’s even some real-world evidence that SRI can result in outperformance. The MSCI KLD 400 Social Index is an index of 400 U.S. companies with high ESG ratings and excludes companies whose products have negative social or environmental impacts.

Since its inception on May 31, 1990, the index had an annualized return of 10.50% versus 10.08% for the S&P 500 Index (per FactSet Inc.)

Clients increasingly demand that their portfolio managers take ESG issues into consideration when building ­portfolios. Advisors would do well to get up to speed on ESG-related terminology and understand the impact ESG mandates might have, if any, on portfolio returns.
