In the past decade, investors have increasingly sought out investment products that incorporate environmental, social and governance (ESG) criteria in their portfolio construction process. Some are seeking ways to align their investment portfolio with their values, while others see ESG criteria as important tools to assess a global stock’s long-term performance potential. This growing demand has led to a variety of methodologies for implementing ESG strategies, some of which may create risks such as unfavorable industry, region or country concentrations and tracking error against market-cap weighted benchmarks.

In this paper, we explain how an approach that integrates analysis of ESG key performance indicators (KPI) into traditional portfolio selection criteria may help overcome the limitations of other global ESG strategies, while pursuing the potential for an enhanced risk return profile. We then explain the methodology that the FlexShares STOXX Global ESG Impact Index Fund (ESGG) uses to generate a diversified global equity ESG portfolio.

THE CHALLENGES OF BUILDING A DIVERSIFIED GLOBAL ESG PORTFOLIO

Our research suggests that there is growing interest in ESG investing among global investors who want to align their portfolios with their values, or who believe that ESG criteria can impact a company’s long-term business performance. In response, several methods for ESG investing have sprung up over time.

Some strategies exclude companies based on their business activities, such as oil drilling, tobacco products, or weapons production. Others seek to overweight so-called “best in class”1 global ESG companies, those involved in activities with a social or environmental benefit as well as those demonstrating a commitment to add diversity to their corporate boards, and other positive changes.

Some of these approaches may come with important trade-offs, including limited diversification potential and the chance of weaker risk-adjusted performance. For example, excluding global companies based on their activities alone could remove entire industries or sectors from investment portfolios, causing a potential increase in tracking error compared to market-weighted benchmarks. Similarly, selecting companies based solely upon their sustainability efforts could concentrate a portfolio in certain sectors.

Many investors have begun implementing ESG strategies that examine select ESG-related key performance indicators reported by public companies in their regulatory filings as a way to further assess a stock’s potential risk and returns. We believe that analysis of disclosed ESG data, combined with improved portfolio construction guidelines, may result in a more diversified, ESG tilted global equity investment portfolio. The resulting portfolio could help deliver the potential benefits of global ESG investing while avoiding common pitfalls such as insufficient diversification.

APPLYING ESG KPIS IN THE GLOBAL PORTFOLIO SELECTION PROCESS

The FlexShares STOXX Global ESG Impact Index Fund is an ETF that seeks enhanced risk return characteristics relative to the broad large-cap global equity market from an ESG portfolio by tracking a custom index, the STOXX Global ESG Impact Index.2 STOXX is a leading index provider in Europe, owned by the Deutsche Borse, which operates the largest stock exchange in Germany, and the SIX Swiss Exchange, the leading independent stock exchange in Europe.

3 distinct categories of criteria

The universe of stocks under consideration in the index are all companies listed in the STOXX Global 1800 Index.3 Then, STOXX excludes:

  • Companies that do not adhere to the U.N. Global Compact principles
  • Companies involved in controversial weapons
  • Coal miners

Next, the index employs bottom-up analysis of publicly available data to evaluate more than 150 ESG-related KPIs with broad representation among the three distinct categories of criteria—environmental, social and governance. STOXX pays particular attention to the KPIs its research has shown to have been most influential in determining risk and return. Based on this analysis, each stock receives an aggregate ESG score, and the bottom 50% of companies are excluded from the index.

The custom index’s holdings from among the remaining 50% are tilted in favor of constituents with higher aggregate scores in an effort to optimize risk-adjusted return. Finally, constraints are applied in the portfolio construction process to maintain sector and style neutrality compared to the index. In addition, the final portfolio targets holdings of no more than 5% in any single company.

SEEKING IMPROVED DIVERSIFICATION AND ENHANCED RISK/RETURN PROFILE

We believe that measuring the impact of KPIs on a global stock’s potential risk/ return profile provides a holistic and diversified approach to ESG investing—one that identifies globally sustainable companies while potentially reducing portfolio risk and enhancing long-term investment performance.

Since the risks related to ESG criteria differ across industries, our research indicates it is prudent to evaluate the impact of KPIs on a sector-by-sector basis. By focusing on the ESG criteria that research has shown to be most material in specific sectors/ industries, The STOXX Global ESG Impact Index is designed to target companies that exhibit positive risk and return versus a market-cap weighted index. Composite ESG scoring may also help provide wider screening across all three categories of environmental, social and governance criteria.

We believe this bottom-up approach parallels best practices employed by a wide swath of portfolio managers when they evaluate, sort and select global companies for other types of investments. Employing diversification controls for style and sector exposure may further enhance diversification, which we believe may help avoid the risks associated with ESG strategies such as exclusionary screening.

CONCLUSION

While ESG investments have grown in popularity, our belief is that the criteria used to evaluate ESG performance are not universally applicable across sectors. As a result, common selection methodologies may make ESG portfolios prone to sector concentrations and tracking error that unnecessarily limit opportunities.

The FlexShares STOXX Global ESG Impact Index Fund is designed to use a bottom-up approach to portfolio selection to help improve sector diversity and manage potential tracking error. By relying on a methodology that applies ESG scoring early in the selection process, the Fund integrates ESG principles with more traditional portfolio analysis tools to maintain a diversified core equity investment strategy while tilting toward ESG criteria. This methodology, along with sector and security constraints, may offer the potential for a broadly diversified ESG portfolio that can help align an investor’s portfolio with their values.

FlexShares STOXX Global ESG Impact Index Fund (ESGG) is passively managed and uses a representative sampling strategy to track its underlying index. Use of a representative sampling strategy creates tracking risk where the Fund’s performance could vary substantially from the performance of the underlying index. The Fund is subject to environmental, social and governance (ESG) Investment Risk, which is the risk that because the methodology of the Underlying Index selects and assigns weights to securities of issuers for non-financial reasons, the Fund may underperform the broader equity market or other funds that do not utilize ESG criteria when selecting investments. The Fund is also at increased risk of industry concentration, where it may be more than 25% invested in the assets of a single industry. Investments in foreign market securities involve certain risks such as currency volatility, political and social instability and reduced market liquidity. To the extent that the Fund invests in Emerging markets, those investments may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that country, market, industry, sector or asset class. The Fund may also invest in derivative instruments. Changes in the value of the derivative may not correlate with the underlying asset, rate or index and the Fund could lose more than the principal amount invested.
