Static vs. momentum-based ESG rating
Glaciers meltdown, frequent forest fires, Venice under water – more and more cases point to the alarming problem of global warming. Further attention to climate change has been attracted also by Greta Thunberg giving an emotional speech during the UN summit. Growing awareness about the environmental issues is likely to help the funds with ESG tilt in attracting more funds. Caring and conscious investors are willing to contribute to the improving climate conditions with their impact investing – a term applied when the effect from investments outweighs the investment returns.
Usually, ESG ETFs and funds aim to invest in the companies with the highest ESG ratings or in the companies with already established socially responsible and environment-friendly operations, lowest CO2 emissions, lowest amounts of waste generation, with lowest amounts of water use. Interestingly, the biggest contributions to the environment preservation and increased social responsibility can be made by yet imperfect enterprises, which, however, made a commitment to improve and are consequently heading for their goal. With originally lower ESG standards, these companies tend to have higher leverage, as the effect of adopting higher ESG standards will likely have a more positive effect on their cost discipline, risk control, etc. Research indicates that companies with positive ESG momentum tend to perform better than their peers with already developed ESG culture.
Our perception of ESG momentum
To exclude any subjectivity in our judgment on ESG improvement, we have selected only numerical KPIs, which companies publish in their sustainability reports. Therefore, analytical sample includes only those companies, which care about ESG as it was evidenced in published ESG reports so that the minimum level of compliance with standards of being socially and environmentally responsible is ensured. In total 12 criteria were selected: four in each area – Environment, Social and Governance. ESG momentum rating covers most important quantitative ratios, including board independence, salary gap, lost time incident rate as well as resource consumption and CO2 emissions to name a few. All absolute values, such as energy consumption or CO2 emissions, were taken in the context of total sales.
We have also concentrated our analysis on European companies as US firms are not yet sufficiently advanced in providing extensive data on ESG performance indicators, leaving scarce possibility for thorough analysis.
ESG score and ESG momentum by industry
Average momentum ratings for the sectors did not come as a surprise: Utilities are the best in improving their ESG standing, followed by Materials and noteworthy they both have low absolute ratings. Healthcare companies, which are already playing in higher ESG league, have the lowest ESG momentum.
Fundamental Quality = Good ESG. Is there space for further ESG improvement?
It was stated many times that fundamental quality goes hand in hand with good ESG management, which facilitates risk reduction, operational transparency, capital attraction, cost control.
Knowing that quality companies usually have high ESG scores, one would expect them to demonstrate lower ESG momentum – utmost efficient companies cannot make a leap in improvement in every dimension every year. So, the average ESG momentum rating for quality companies in 2019 is 12.4, while the market’s average is 13.3. Still, Financials and Industrials within the attractively valued quality universe managed to do better than the market in ESG improvement.
EU Quality companies vs. MSCI Europe: ESG Score and ESG momentum
There are also a few ESG role models among quality firms. For instance, the world’s leading software company, SAP, not only has excellent financials, but also excellent rating on ESG score and ESG momentum (improved on 9 out of 12 metrics in 2018). German IT giant has improved particularly well in the environmental area dedicating itself to sustainable development: uses 100% green energy for data-centers and buildings, phases out single-use plastics, plans to become carbon neutral till 2025.
ESG momentum and performance
Now, the question is whether ESG momentum is worth the same pile of analyst attention as does the static ESG score. The research on ESG momentum says that, in fact, it could generate even more value (Factset, 2019; Societe Generale, 2019). We have checked this statement by considering the value-added of ESG score and ESG momentum to the equity performance in the comparative analysis, which covers the assessment of the last four years – the longer range is unavailable due to the insufficiency of older ESG data.
The relative performance of good vs. bad companies according to ESG score and ESG momentum (MSCI Europe)
During this short period considered, stock selection based on pure ESG rating did not help in generating excess returns, while companies with improving ESG ratings managed to beat the ones with deteriorating ESG KPIs.
ESG hype gains popularity, so more research will follow on static and dynamic ESG scores. But already now there is a lot of evidence in favor of the positive influence they have on corporate performance, reputation and valuation. And obviously the current situation speaks in favor of picking the companies that make a greater leap in becoming more environment-friendly, socially responsible and well-governed.
