ESG Fund Investing: The pursuit of sustainable alpha

Investors are increasingly beginning to incorporate ethical considerations into their investment decisions, a development which has given rise to the ESG framework over the years. Despite the implementation challenges which arise when screening investments against acceptable environmental, social and corporate governance themes, the trend towards a more conscientious approach to investment is here to stay, especially from the perspective of large institutional investors. Fund managers, for both actively and passively managed investment vehicles are balancing their quest for superior returns with the need to meet investor demand for responsible investing. Further, an understanding that such an approach to investment can translate into ‘ESG-induced alpha’ for managers is further helping the cause of ethically guided investing. This article looks at the performance of funds, both long-only absolute return vehicles and hedge funds, with an active ESG investment framework and how they have performed over the years.

The Eurekahedge ESG Fund Index, which tracks the performance of 631 active fund managers who incorporate ESG framework in their investment processes has gained 5.47% as of August 2019 year-to-date. This compares with the 12.75%, 5.21% and 6.22% returns of the MSCI ACWI ESG Leaders Index, the Eurekahedge Islamic Fund Index2 and the custom Eurekahedge Equity ex-ESG Fund Index3 . Meanwhile, the average global hedge fund has posted a small gain of 6.58% over the same period. ESG fund managers closed 2017 with a 12.60% gain on average, outperforming the 6.97% return posted by the Eurekahedge Islamic Fund Index over the year, but still trailing behind the performance of ESG equities as represented by the MSCI ACWI ESG Leaders Index which edged 20.67% higher on the back of the 2017 equity market rally. On the other hand, ESG fund managers were able to outperform the equity index in 2018, which saw the escalation of the US-China trade war and other political concerns around the globe. The Eurekahedge ESG Fund Index slumped 6.03% throughout 2018, which compares to the 10.43% decline registered by the MSCI ACWI ESG Leaders Index over the same year.

Figure 1 below depicts the performance of the Eurekahedge ESG Fund Index versus comparable benchmarks since the end of 2007. Over the period depicted below, the ESG fund managers tracked by the Eurekahedge database have generated an annualised return of 3.52%, ahead of Islamic funds and the global ESG equities which have gained 1.84% and 2.64% per annum respectively. On the other hand, ESG fund managers underperformed their non-ESG peers utilising long/short equities strategy which have returned 4.50% per annum since the end of 2007. However, looking at the post-crisis period starting from the end of 2008, ESG fund managers managed to generate an annualised return of 7.91%, leaving the Eurekahedge Equity ex-ESG Fund Index behind by more than 80 basis points over the same period.

Table 1 summarises the key performance statistics for the Eurekahedge ESG Fund Index relative to comparable benchmarks. Key takeaways include:

  1. ESG compliant funds in the Eurekahedge database have generated better annualised returns compared to Islamic funds over the last two, three, and five-year periods (1.56%, 4.70%, and 4.41% respectively). However, they had been trailing behind the MSCI ACWI ESG Leaders Index which was designed to track the performance of companies with high ESG compliance.

  2. Non-ESG compliant equity funds outperformed the Eurekahedge ESG Fund Index over the last two years by returning 2.04% per annum. Over the longer three and five-year periods, ESG compliant funds have generated better returns and Sharpe ratios.

  3. In terms of risk-adjusted performance, the Eurekahedge ESG Fund Index has generated better Sharpe ratios over the two, three, and five-year periods compared to the benchmark MSCI index and Islamic funds.

  4. Compared against their non-ESG peers, ESG compliant funds managed to post lower volatilities and marginally better annualised returns over the last three and five-year periods. However, the fund managers tracked by Eurekahedge Equity ex-ESG Index were better positioned to capture the upward rally of the global equity market throughout the first eight months of 2019.

Figure 2a and Figure 2b below offer important insights into understanding the return drivers for the Eurekahedge ESG Fund Index. The first chart depicts the performance attribution for monthly returns based on regional mandate, whilst the second chart accomplishes the same based on strategy.

With reference to Figure 2a below, the constituents of the Eurekahedge ESG Fund Index are sorted based on their regional exposure into three buckets: developed markets focus, emerging markets focus or a global mandate that spans across both. As the chart below reveals at a glance, emerging market mandated ESG funds feature heavily in the current index constituent base and have been the major factor influencing returns both on the upside as well as the downside. The implementation of ESG frameworks especially in marketing emerging market mandated funds to sophisticated overseas investors could potentially help add to the appeal for such funds especially in relation to themes such as sound corporate governance and social responsibility.

Figure 2b provides the breakdown of the ESG index performance and divide the index constituents into two categories: hedge fund strategies and long-only absolute return strategies. As is evident in the figure, funds utilising long-only absolute return strategies are key drivers of returns among the constituents of the Eurekahedge ESG Fund Index, indicating the tilt towards emerging market mandated long-only absolute return strategies within the ESG fund space. However, seemingly contradictory to this observation, roughly 75% of the current Eurekahedge ESG Fund Index utilised hedged strategies. This could be explained by the higher magnitude of the returns of long-only absolute return funds, driven by their higher volatilities compared to hedged strategies which employ short positions to reduce exposure against the equity markets.

Over the last five years, the Eurekahedge ESG Fund Index has managed to generate excess returns over its benchmark indices, with alpha of 0.26% against the MSCI ACWI ESG Leaders Index and 0.30% against the Eurekahedge Islamic Fund Index. ESG fund managers have also delivered 0.14% alpha over their non-ESG competitors as represented by the Eurekahedge Equity ex-ESG Fund Index over the same period. This would signify that the additional research conducted by fund managers to determine the ESG compliance of their securities also helped them deliver superior performance, refuting the common misconception that the additional costs entailed by the ESG framework would translate into inferior performance. Furthermore, considering the increasing ESG awareness globally, incorporating ESG principles into the investment philosophy can help add another compelling dimension for hedge fund managers seeking institutional capital – especially when it does not add to fees or come at the expense of returns.
