Social and ecological research
Decarbon-now: Climate Transition: Why Decarbonize Now Not Later? A Literature Review from An Asset Owner Perspective by Wendy Fang, Skye King, Michael Mi, Mohamed Noureldin, Ben Squires, Eliza Wu, and Jing Yu as of Jan. 9th, 2025 (#39): “… Integrating insights from climate science, economics, and finance, we present three key angles: (1) Scientific evidence demands urgent action to avert irreversible damage from exceeding 1.5◦C global warming. (2) Economic models may underestimate climate impacts by not fully accounting for systemic shocks, nonlinearities, and tipping points. (3) Asset pricing theory predicts a higher carbon premium (higher cost of capital for high-climate-risk assets), yet empirical evidence shows that green assets outperform brown counterparts, especially in recent years. We reconcile this debate by arguing that markets have not fully priced in climate risks; investors’ underestimation of the urgency and magnitude of damage leads to complacency and inaction, exacerbating irreversible physical risks in a feedback loop. Thus, expecting a carbon premium is unwarranted until equilibrium is reached …“ (abstract).
Intertwined risks: Nature Loss and Climate Change: The Twin-Crises Multiplier by Stefano Giglio, Theresa Kuchler, Johannes Stroebel, Olivier Wang as of Jan. 2025: “We study the economic effects of the interaction of nature loss and climate change in a model that incorporates important aspects of both processes. We capture the distinct ways in which they affect economic activity—with nature constituting a key factor of production and climate change destroying parts of output—but also the ways in which they interact: climate change causes nature loss, and nature provides both a carbon sink and adaptation tools to reduce climate damages. Our analysis of these feedback loops reveals a novel amplification channel—the Twin-Crises Multiplier—that systematically affects optimal climate and nature conservation policies” (abstract).
Green investment gap: Investing in Europe’s green future – Green investment needs, outlook and obstacles to funding the gap by Carolin Nerlich and many more from the European Central Bank as of Jan. 10th, 2025 (#59): “The green transition of the EU economy will require substantial investment to 2030 and beyond. Estimates … all point to a requirement for faster and more ambitious action. Green investment will need to be financed primarily by the private sector. … capital markets need to deepen further, especially to support innovation financing. Progress on the capital markets union would support the green transition. Public funds will be vital to complement and de-risk private green investment. Structural reforms and enhanced business conditions should be tailored to encourage firms, households and investors to step up their green investment activities” (abstract).
Regulation benefits: More Constraints, More Consensus? How Regulation Shapes Investor Information Asymmetry by John M. Barrios, Zachary R. Kaplan, and Yongzhao Vincent Lin as of Nov. 23rd, 2024 (#144): “We examine the relation between product market regulation (PMR) and information asymmetry among investors. … greater PMR significantly reduces bid-ask spreads and insider trading. This reduction in information asymmetry is driven by decreased operating profit volatility, which lowers uncertainty about firm operations. However, the impact of PMR diminishes when government commitment to regulation is weak, particularly during periods of elevated economic policy uncertainty or among politically active firms capable of strategically influencing regulation …” (abstract).
ESG investment research (in: Return on sustainability)
ESG overview: A Review on ESG Investing by Javier Vidal-García and Marta Vidal as of Jan. 11th, 2025 (#86): “The overall results show significant heterogeneity, evidencing three predominant positions: some research suggests that ESG investments outperform conventional ones, others indicate a lower performance for ESG, implying a premium paid for sustainability criteria, and a third position indicates an equivalence in performance between the two. These discrepancies are attributed to the period analyzed, the sample, the statistical methodology, the culture and the ESG rating provider” (p. 25/26). My comment: If the performance is similar, why invest traditionally instead of sustainably?
ESG disclosure effects: Profit or Planet? Both! ESG Drivers of Efficient Portfolios and the Costs of Disclosure by Nico Rosamilia as of Jan. 2nd, 2025 (#13): “This study integrates the ESG variables in the five-factor asset pricing model by Fama and French and a model-free methodology represented by machine learning. The markets‘ main focus for the governance pillar relates to board characteristics and functions. The social pillar shows the significance of employee-related issues, while greenhouse emissions for the environmental pillar. The machine learning results provide the main drivers yielding the excess returns of the best sustainable portfolios. Finally, we test the ESG prediction power of fundamentals and find that ESG disclosure diverts company resources toward long-term sustainable investment over investment for profitability in the short term“ (abstract).
Confusing supplier ESG? ESG Alignment and Supply Chain Dynamics: Evidence from U.S. Customer-Supplier Relationships by Stefan Hirth and Sai Palepu as of Jan. 15th, 2025 (#21): “We study the role of Environmental, Social, and Governance (ESG) alignment in shaping customer-supplier relationships within U.S. supply chains. … we find that major customers significantly influence supplier ESG performance, with a 6.9% increase linked to one unit increase in the major customer ESG scores. Positive ESG divergence, where a supplier outperforms its major customer, increases the likelihood of relationship termination by 18.1% …. Replacement suppliers generally exhibit higher ESG ratings than their predecessors …” (abstract). My comment: The “positive ESG divergence” confuses me, because I don’t expect suppliers to stop selling to lower-ESG customers and neither I expect customers stop buying from higher-ESG suppliers.

SDG investment research
Climate bond potential: Climate-linked bonds by Dirk Broeders, Daniel Dimitrov, and Niek Verhoeven from the European Central Bank as of Jan. 10th, 2025 (#68): “Climate-linked bonds, issued by governments and supranational organizations, are pivotal in advancing towards a net-zero economy. These bonds adjust their payoffs based on climate variables such as average temperature and greenhouse gas emissions, providing investors a hedge against long-term climate risks. … The price differential between climate-linked bonds and nominal bonds reflects market expectations of climate risks. This paper introduces a model of climate risk hedging and estimates that approximately three percent of government debt in major economies could be converted into climate-linked bonds” (abstract).
Water opportunity costs: The Pricing of Water Usage by Adrian Fernandez-Perez, Ivan Indriawan and Yiuman Tse as of Jan. 14th, 2025 (#61) “…we examine the relationship between firms’ water usage and stock returns. Our analysis shows a negative relationship between water usage and excess returns, with high-water-usage firms generating lower returns compared to their industry peers. This effect is stronger in high-water-consumption sectors like mining and manufacturing. We also find a positive link between water usage and operating costs …” (abstract).
Return on sustainability: The Sustainability Dividend: A Primer on Sustainability ROI by Matteo Tonello as of January 4th,2025: “… companies face growing pressure to determine the return on investment (ROI) of their sustainability efforts, a critical factor in gaining stakeholder trust and ensuring long-term success. This report highlights insights from a series of Member roundtables and polls, discusses the current state of sustainability ROI, and provides guidance for companies to get started. … Few companies are capitalizing on the power of authentic and transparent sustainability communication to showcase their sustainability results and gain internal and stakeholder support for sustainability“ (p. 2).

Low-beta outperformance? Persistence in Alphas without Persistence in Skill by Sina Ehsani and Juhani Linnainmaa as of Jan. 8th, 2025 (#33): “The persistence of mutual fund alphas is often viewed as evidence that some funds possess skill and that this skill persists. … high-alpha funds are predominantly low-beta funds and vice versa. Thus, a strategy of investing in high-alpha funds benefits not from skill, but from a betting-against-multiple-betas effect …” (abstract).
Active ETF (AETF) benefits: ETFs as a disciplinary device by Yuet Chau, Karamfil Todorov and Eyub Yegen as of Jan. 6th, 2025 (#126): “… Unlike mutual fund shares, ETF shares can be shorted, which enables investors to bet against manager performance. We show that AETFs exhibit over five times greater flow-performance sensitivity than mutual funds, indicating that AETF managers face harsher penalties for poor performance. When an underperforming manager joins an AETF, investors respond by shorting more shares of the fund. Consequently, this manager is more likely to exit the fund management industry, thereby enhancing overall sector efficiency and allowing more high-performing managers to remain. Moreover, the stocks held within AETFs exhibit improved price informativeness. We also find that AETF managers outperform both mutual fund and passive fund managers” (abstract).
Sensible trend-following: Can the variability of trend-following signals add value? By Philippe Declerck and Thomas Vy as of Dec. 6th,2024 (#67): “We document that there is information in the variability of binary signals used to build a cross-asset trend-following strategy. This information may help building trend-following strategies with slightly higher Sharpe ratios. This added value may come with higher maximum drawdown to vol ratios for short lookback periods (up to one month), while the longest period tested (2.5 months) lead to a reduction of both ratios. The optimal results are obtained for observation periods of 1 to 2 months” (abstract). My comment: Since quite some time, I use 40-day averages for risk-signals if clients want to have risk-managed portfolios.
AI model overload: Design choices, machine learning, and the cross-section of stock returns by Minghui Chen, Matthias X. Hanauer and Tobias Kalsbach as of Dec. 2nd, 2024 (#3367): “We fit over one thousand machine learning models for predicting stock returns, systematically varying design choices across algorithm, target variable, feature se lection, and training methodology. … we observe a substantial variation in model performance, with monthly mean top-minus-bottom returns ranging from 0.13% to 1.98%. These findings underscore the critical impact of design choices on machine learning predictions, and we offer recommendations for model design. Finally, we identify the conditions under which non-linear models outperform linear models“ (abstract).

Unterstützen Sie meinen Researchblog, indem Sie in den von mir beratenen globalen Small-/Mid-Cap-Investmentfonds (siehe FutureVest Equity Sustainable Development Goals R – DE000A2P37T6 – A2P37T) investieren und/oder ihn empfehlen.
Der Fonds konzentriert sich auf die UN-Ziele für nachhaltige Entwicklung mit durchschnittlich außerordentlich hohen 99% SDG-vereinbaren Umsätzen der Portfoliounternehmen und verwendet separate E-, S- und G-Best-in-Universe-Mindestratings sowie Aktionärsengagement bei derzeit 28 von 30 Unternehmen (siehe auch My fund).
Zum Vergleich: Ein traditionelle globaler Small-Cap-ETF hat eine SDG-Umsatzvereinbarkeit von 5%, für einen Gesundheits-ETF beträgt diese 1% und für einen ETF für erneuerbare Energien 44%.
Insgesamt hat der von mir beratene Fonds seit der Auflage im August 2021 eine ähnliche Performance wie durchschnittliche globale Small- und Midcapfonds (vgl. z.B. Fonds-Portfolio: Mein Fonds | CAPinside und Globale Small-Caps: Faire Benchmark für meinen Artikel 9 Fonds?).
Ein Fondsinvestment war also bisher ein „Free Lunch“ in Bezug auf Nachhaltigkeit: Man erhält ein besonders konsequent nachhaltiges Portfolio mit markttypischen Renditen und Risiken.
