Constructing Social Portfolios: A Quantitative versus Screening Approach

When we talk about ESG, one could argue that there is a strong bias focused on climate investing, reaching net zero targets as well as good corporate governance and diversity themes. But there is much more to ESG. The “Social” dimension of ESG is hugely under explored and developed and covers under studied issues such as how companies treat their employees and care for the responsibility of their products. Still further, assessments linked to human rights codes and social impacts is only now receiving the attention it truly deserves. Although the importance of these topics is undisputed, we see that attention to particularly address the social dimension has been lacking, whereas awareness of other ESG risks has been rising immensely during the past years. 

Not only is the general knowledge and focus on the social dimension of ESG limited, its overall  implementation in portfolio management has not been sufficiently experimented with and addressed.

The delay to properly implement the “S” in ESG is often explained because of the challenges to quantify, assess, and integrate social factors generally.

However, this argument should not be a sufficient justification for neglecting the “S” in ESG and for investigating a possible relationship between a good social rating and superior financial performance. To tackle this lack of awareness, we constructed two portfolios which integrate Refinitiv’s Social ratings based on different integration strategies and test their performance towards the market between 2012-2021.

When integrating social – or other ESG – ratings into the investment process, we find there is often disagreement on how to best consider these factors in portfolio construction. Currently, it is most common to apply screening or best-in-class strategies. These approaches aim to remove assets that do not fulfill certain criteria from a defined investment universe. Negative screening would mean to remove those companies that perform worst from the pool of assets. Inversely, an investor could also only continue with those firms who at least have a certain minimum rating. For both approaches, the portfolio weights are then allocated to the assets that remain. This is done using conventional indicators such as value, size or expected risk-adjusted returns. In our study, we, however observe a clear shortcoming of this approach: After screening out the worst 10% “social performers” and allocating weights based on a risk-return trade-off, the portfolio does not necessarily promise a higher overall ESG score than a portfolio would reach which does not consider the ratings at all. Although the portfolio yields a solid financial performance, this raises the question whether any ESG-related impact has been made with this integration approach.

To make sure an investor can improve his exposure to assets that score well in the social dimension, we integrate the rating scores directly into the optimization problem of our second portfolio. This leads to a very different outcome on the social rating:

Looking closer at the mechanics of this approach, we extend the traditional Sharpe Ratio with the ESG factor, meaning to add by how much it a company “outscores” the market average. This results in the following “Social Sharpe Ratio”:

We add a fifty percent weight split, which can be flexibly adjusted towards investor preferences. And we now balance a risk-return-social trade-off. This explains why the second approach over 9 years constantly beats the market average in respect to the integrated Social factor without sacrificing any performance on the financial side. In fact, we find that in 5 out of 9 years, the second strategy would have also led to higher risk-adjusted returns measured by the Sharpe ratio. Moreover, returns were consistently higher compared to the market benchmark. This result is quite remarkable, given that it is often questioned whether investors need to sacrifice returns in order to make their investments more socially responsible. 

Lastly, our study resulted in one more unforeseen twist when it comes to integrating ESG ratings. That is, the question whether we can actually trust the rating scores. To answer this, we must first understand how scores are created. Rating providers look at an immense amount of publicly disclosed information, reports and policies. And based on what company’s report, rating scores are aggregated. However, it is clear that a firm would only report on things they do well. In fact, we observe that with increased reporting, ESG scores also improve. But what about the real-life actions and impacts? Some rating providers offer a combined score, which also considers media reports on the involvement in controversial actions. As these scores are only available at an aggregate level, we calculate them on a single-pillar level using Refinitiv’s methodology, which adjusts for firm size and industry. Looking at specific examples in our portfolios, we found that the impact of such controversy involvement on the overall score could still be larger. Nevertheless, we stress that in order to have a complete picture of a firm’s ESG behavior, the impact of these controversies needs to be reflected in investment decisions. 

To sum up, given the results of our research, there are three things we aim to highlight:

  • It is crucial to increase investors’ awareness of “Social” matters and provide a better landscape for impact investments in this specific dimension.
  • Integrating ESG ratings does not always promise a better ESG performance for the whole portfolio. Therefore, it is necessary to focus on strategies that lead to actual impact.
  • Third, looking beyond the information that is disclosed by companies themselves, more attention should also be addressed to “real life actions” when making investment decisions.

Institutions matter: The importance of institutional quality when embedding sustainability within the capitalistic realm

By Lisa Bernt Elboth, Adrian Rudolf Doppler, & Dr. Kristjan Jespersen

◦ 5 min read ◦

Institutions not only structure any sort of social interaction [1], but are also essential in solving societal problems [2], such as climate change and the associated threat towards a fair and just future. It is not without reason that the United Nations particularly emphasized institutional progress within SDG 16 [3] to advance to a more effective, inclusive, and accountable society. In a recent study, it was found that institutions matter to a great extent when scrutinizing the relationship between corporate financial performance (CFP) and ESG performance. More specifically, the institutional environment a company finds itself in determines whether sustainable business practices get transformed into financial returns.

The claim that more sustainable companies are outperforming their not so sustainable peers is not new [4] and the consequent shift of investors’ preferences towards more sustainable companies has been taking place with increasing speed over the last decade [5]. Associated wake-up calls and the urge to take ESG into consideration are not surprising either. Besides the alleged desire of investors for a just and sustainable future, this shift is more likely based on the theory that sustainable finance delivers abnormal returns [6]. But is the relationship between sustainable behavior and financial performance as straightforward as it is disseminated? Are more sustainable corporations indeed more likely to achieve better financial results regardless of where they are and what they do?

In fact, when utilizing ESG scores, rankings, and performance as a proxy for sustainable behavior, two meta-analyses [7] [8] concluded that in most empirical studies the resulting relationship was not as simplistic, universal or linear as it is often propagated. In a corresponding literature review, the researchers also identified a large number of discrepancies among scholars in how to statistically model the relationship, what control variables to use and how to even quantify the dependent and independent variables of focus. Following these insights, the researchers uncovered a determining factor in establishing and shaping the emphasized relationship – institutional quality.

Key Findings

The final sample consisted of datapoints from 6,976 corporations, situated in 75 different countries over a period of eleven years or, specifically, from 2009 to 2020. Subsequently, these were analyzed applying fixed effects panel regression models. Both an accounting- and a market-based measure were used to quantify corporate financial performance, respectively, Return on Assets (ROA) and Tobin’s Q. Meanwhile, ESG performance was proxied by ESG scores from Refinitiv (former Thomson Reuters). The variables associated with institutional environment were split into 

  1. Institutional Quality, calculated through a factor analysis and based on the World Governance Indicators from the World Bank and 
  2. Industry Sensitivity, a dummy variable equal to 1 if the GICS industry of a firm was deemed sensitive towards ESG.
Institutions are among the determinantal factors for the link 

Interestingly, the general statistical analysis of ESG and CFP did not yield any significant results, however, when moderating effects stemming from the institutional environment were introduced, this changed. Under high institutional quality, the researchers found a positive relationship between ESG scores and financial performance. Contrarily, the relationship was negative under low institutional quality. Exemplified below by the case of Finland 2012, Argentina 2018 and Zimbabwe 2012, institutions can be seen as the determining factor for direction of the focal link. Furthermore, the industrial environment a corporation finds itself in was found to affect the relationship ambiguously. Generally, sensitive firms seem to receive relatively less financial gain for improved ESG performance, and it may even be negative.

Possible explanations for such dynamics
  • Legal institutions, such as environmental regulations, labor laws or health and safety requirements, can serve as the means of reflecting sustainable behavior inside a company’s balance sheet. Finland was for instance the first country to introduce a carbon tax capturing corporate pollution by giving it a price and hence affecting accounting profits.
  • In highly corruptive settings, where the trust of the general public is lacking, the likelihood of sustainable activities being perceived as greenwashing and thus not rewarded by investors, could be another reason for an inverse relationship in low institutionally developed regions. 
  • In line with the previous, when accountability is low, and corporate entities can disclose information without third party verification, it could be relatively easy to stay focused on short-term profits through unsustainable practices but still receive a better ESG rating.  
  • In environments with low institutional quality, banks tend to only give out short-term loans in order to reduce their own risks. This can lead to a vicious cycle of corporate lenders also only focusing on short-term profit maximization which then again decreases their access to capital, constraining their ability to engage in long-term sustainable practices.
Putting the SO WHAT into practice

When setting out for systemic change, it is important to ensure the necessary institutional environment in order to encourage individuals, as well as corporate entities to act in the best interest of the entire society and the planet. Thereby, a bottom-up approach focusing on incentivizing every individual and a top-down approach, fostering legal macro-level change can be synthesized, leading to the best possible outcome. These institutions should seek to maximize accountability, transparency, and mechanisms to internalize negative externalities. Corporations within such environments should fully leverage opportunities associated with sustainable practices, such as cheaper access to capital, in order to incrementally advance the progress towards a just space for humankind. Corporations, which are especially sensitive towards ESG related elements irrespective of their ESG scores, should aspire to enhance their own credibility, as this might award them with a competitive advantage. Lastly, societies with high institutional quality should strive for teaching about their institutions and the associated benefits to everyone else, as a global problem can only be solved on a global level.

Sustainability claims: In what sense are they performative?

By Lars Thøger Christensen

The number of products advertised as “green” or climate neutral has exploded in recent years, according to several newspaper articles. Should we be alarmed? To some extent, yes. In addition to cases of blatant fraud and manipulation, there is reason to be concerned when a plethora of green labels for products – ranging from milk over burgers to gasoline – competes for attention, especially when the variety confuses understandings of what it means to be sustainable.

Moreover, since carbon offset programs tend to obscure the fact that neither air travel nor fashion clothing is or can be CO2 neutral, the need to question and test green advertising claims is more pressing than ever. It is therefore commendable that politicians and NGOs in some countries call for more control with corporations that claim to market green or CO2 neutral products. 

The growth in green advertising claims attracts increased scrutiny, regulation and control.

At the same time, the expansion in green advertising claims illustrates the growing social, political and economic premium put on sustainability. Even if many such claims are superficial and hypocritical, their combined existence is performative beyond what individual corporations, NGOs and regulators can imagine and control. 

When all social actors express the significance of sustainability, something has changed.

Scholars of communication often emphasize that communication is constitutive of organizational and social reality. Communication, in their view, is performative because it does something more than simply describe a preexisting reality. Yet, in what sense does this logic apply to issues of climate change and the broader sustainability arena? 

To what extent has communication performative potential in the sustainability arena?

Critics of the performative view on communication view argue that green messages often fail to change anything, either because the senders are insincere or because larger social forces, such as profit motives or efficiency demands, override any talk about sustainability. The power of sustainability communication to shape organizational practices is therefore often described as naïve or overly optimistic. These are important objections to the performativity perspective. Yet, communication still plays a significant role in instigating better practices.

The articulation of sustainability ideals is often “the leading incident” in its performance (Austin, 1962, p. 8).

It is certainly true that sustainability communication is insufficient in and of itself to ensure more sustainable practices. Some sustainability claims may even prevent organizations from moving in the right direction. Nonetheless, communication about sustainability is an important dimension of sustainable action. Without a communicative engagement of major corporations with the values and ideals of sustainability, changes in that arena are likely to be significantly slower. 

Interestingly, critique and control of sustainability claims may help such claims to perform.

Talk about sustainability and green products tend to attract attention of critical stakeholders and increase internal and external pressure to walk the talk. Bold statements combined with public exposure and critique are important dimensions of what we might call the performativity “cocktail”. Green advertising claims and public statements about CO2 neutrality can be used to apply pressure on corporations and remind them of their promises. If major corporations, out of fear of attracting negative stakeholder attention, decide to remain silent on the sustainability issue, critics and regulators have less material to work with. In other words, a willingness on the part of corporations to expose themselves to critique is key.

Communicative performativity in the sustainability arena is a macro phenomenon.

Obviously, an organization does not become sustainable by simply “talking green”. In fact, it is a mistake to think of performativity – especially in complex areas such as sustainability – as a result of discrete and isolated organizational messages or claims. It doesn’t work that way. Even with the best intentions, green talk takes considerable time and effort to materialize into more sustainable practices. Moreover, it is rarely an organizational effect. Performativity is an outcome of multiple claims that are repeated and reformulated again and again over time and across multiple organizations, public as well as private. The sedimented effect of such dynamic interaction that lead to what Butler (2010) calls “socially binding consequences” (p. 147).

The performativity of sustainability claims should be understood as sedimented effects of multiple claims and understandings. 

The communicative performativity of sustainability claims involve reactions of stakeholders, competitors, legislators and consumers who are variously affected, inspired or provoked by the claims to expect and demand better practices. Still, there is no guarantee that the claims will stimulate significant changes. That, of course, is true for all types of messages. Messages and claims can be ignored, forgotten or outright contradicted by subsequent claims or other types of action. Without the claims, however, society and the physical environment is likely to be worse off. The trick is to use them actively to remind the senders of their social and environmental responsibilities.
