  • Market greenness predicts liquidity shocks and stock pricing errors

    What the study found

    The study found that market greenness, meaning the market’s environmental, social, and governance (ESG) performance, predicts liquidity shocks during periods plausibly linked to changes in investors’ ESG tastes. It also found that ESG-related liquidity helps explain stock returns and pricing errors beyond what classic risk factors capture.

    Why the authors say this matters

    The authors conclude that shifts in investors’ ESG tastes may generate alphas, which are returns not explained by standard risk factors, and that these effects are partly captured by ESG-related liquidity. They suggest this new liquidity measure improves the fit of asset-pricing models compared with the Pástor-Stambaugh liquidity measure in the period they study.

    What the researchers tested

    The researchers built on the Pástor-Stambaugh liquidity measure, a standard way to study how trading conditions affect returns, and on an equilibrium model that includes investors’ ESG preferences. They tested whether market greenness predicts liquidity shocks, whether ESG-related liquidity is explained by established risk factors, and whether forecasts from their model reduce stock alphas.

    What worked and what didn't

    Market greenness predicted Pástor-Stambaugh liquidity innovations in 2015–2019. Forecasts of ESG-related liquidity reduced stock alphas more effectively than the Pástor-Stambaugh liquidity measure over the period when market greenness predicted liquidity, and ESG-related liquidity was not spanned by well-established risk factors.

    What to keep in mind

    The abstract does not provide detailed limitations beyond the timing of the main results, which are described for 2015–2019 and before 2020. It also does not describe the exact data sources or empirical design in detail.

    • Market greenness predicted liquidity shocks during 2015–2019.
    • ESG-related liquidity was linked to stock returns.
    • ESG-related liquidity was not spanned by well-established risk factors.
    • Forecasts from the ESG-related liquidity model reduced stock alphas more effectively than the Pástor-Stambaugh measure before 2020.
    • The authors tie the predictability to shifts in investors’ ESG demand.

  • Natural gas prices and green bonds affect each other over time

    What the study found

    The study found a bilateral relationship between natural gas prices and the green bond market. The pattern changes over time and depends on market conditions.

    Why the authors say this matters

    The authors conclude that green bonds are important for supporting sustainable development goals, but their interaction with transitional energy markets like natural gas is nonlinear and changes over time. The findings indicate that financial strategies may need to be realigned with long-term sustainability goals.

    What the researchers tested

    The researchers used a Quantile-on-Quantile approach, which examines how different parts of one variable's distribution relate to different parts of another's. They analyzed monthly data from 2013 to 2025 to study nonlinear, asymmetric, and state-dependent interactions between natural gas prices and the green bond market.

    What worked and what didn't

    The results indicate that rising natural gas prices are likely to have a negative short-run effect on green bond performance. In contrast, increases in the green bond market have a short-to-medium-term positive effect on natural gas prices, which the abstract links to natural gas's role as a transitional fuel.

    What to keep in mind

    The abstract does not describe specific limitations beyond the study's focus on monthly data from 2013 to 2025. The summary provided does not include details on data sources, robustness checks, or caveats about generalizing the findings.

    • The study reports a bilateral relationship between natural gas prices and the green bond market.
    • Higher natural gas prices are linked to weaker green bond performance in the short run.
    • Growth in the green bond market is linked to higher natural gas prices in the short-to-medium term.
    • The relationship is described as nonlinear, asymmetric, and dependent on market conditions.
    • The authors say the findings may help align financial strategies with long-term sustainability goals.
