Abstract Climate change poses new challenges for portfolio management. In our not-yet-low carbon world, investors face a trade-off between minimizing their exposure to climate risks and maximizing the benefits of portfolio diversification. This article investigates how investors and financial intermediaries navigate this trade-off. After the release of Morningstar’s novel carbon risk metrics in April 2018, mutual funds labeled as “low carbon” experienced a significant increase in investor demand, especially those with high risk-adjusted returns. Fund managers actively reduced their exposure to...

Abstract We construct optimal portfolios of mutual funds whose objectives include socially responsible investment (SRI). Comparing portfolios of these funds to those constructed from the broader fund universe reveals the cost of imposing the SRI constraint on investors seeking the highest Sharpe ratio. This SRI cost crucially depends on the investor’s views about asset pricing models and stock-picking skill by fund managers. To an investor who strongly believes in the CAPM and rules out managerial skill, that is, a market index investor, the cost of the SRI constraint is typically just a few b...

ABSTRACT I demonstrate that skill and scale are mismatched among actively managed equity mutual funds. Many mutual fund investors confuse the effects of fund exposures to common systematic factors with managerial skill when allocating capital among funds. Active mutual funds with positive factor‐related past returns thus accumulate assets to the point that they significantly underperform. I also show that the negative aggregate benchmark‐adjusted performance of active equity mutual funds is driven mainly by these oversized funds.

Abstract We identify fixed-income mutual funds as an important contributor to the unusually high selling pressure in liquid asset markets during the COVID-19 crisis. We show that mutual funds experienced pronounced investor outflows amplified by their liquidity transformation. In meeting redemptions, funds followed a pecking order by first selling their liquid assets, including Treasuries and high-quality corporate bonds, which generated the most concentrated selling pressure in these markets. Overall, the estimated price impact of mutual funds was sizable at a third of the increase in Treasur...

We identify fixed-income mutual funds as an important contributor to the unusually high selling pressure in liquid asset markets during the Covid-19 crisis. We show that mutual fund liquidity transformation led to pronounced investor outflows. In meeting redemptions, funds followed a pecking order by first selling their liquid assets, including Treasuries and high-quality corporate bonds, which generated the most concentrated selling pressure in these markets. The Fed's announced purchase of illiquid securities effectively stabilized mutual fund liquidity transformation and alleviated the sell...

Abstract We provide evidence regarding mutual funds’ motivation to hold lottery stocks. Funds with higher managerial ownership invest less in lottery stocks, suggesting that managers themselves do not prefer such stocks. The evidence instead supports that managers cater to fund investors’ preference for such stocks. In particular, funds with more lottery holdings attract larger flows after portfolio disclosure compared with their peers, and poorly performing funds tend to engage in risk shifting by increasing their lottery holdings toward year-ends. Funds’ aggregate holdings of lottery stocks ...

Corporate bond mutual funds engage in liquidity transformation, raising concerns among academics and policy makers that large redemptions will lead to asset fire sales. We find little evidence, however, that bond fund redemptions drive fire sale price pressure after controlling for time-varying issuer-level information that could also affect funds' trading decisions, using a novel identification strategy that exploits same-issuer bonds held by funds with differing outflows. We attribute our findings, which contrast with those found for equity funds, to funds' liquidity management strategies. B...

ABSTRACT A large and rapidly growing literature examines the impact of misvaluation on firm policies by using mutual fund outflow‐induced price pressure to isolate nonfundamental price variation. I demonstrate that the standard approach to computing outflow‐induced price pressure produces a measure that is inadvertently a direct function of a stock's actual realized return during the outflow quarter, raising doubts about its orthogonality to fundamentals. After removing these direct measurements of return, outflows generate a fairly negligible quarterly decline in returns, with no subsequent r...

This study seeks to determine whether mutual fund decarbonization affects the stock prices of divested firms and contributes to the reduction of these firms' carbon emissions. Using a new methodology to identify equity mutual funds' decarbonization trades, we calculate a metric of decarbonization selling pressure (DSP) on stocks. Controlling for endogeneity and selection bias, we find that high DSP sustainably pressures stock prices downwards. Furthermore, we find that divested firms experiencing a stock price decline subsequently reduce their carbon emissions compared to non-divested firms. T...

Abstract We show that mutual fund investors rely on simple signals and likely do not engage in sophisticated learning about managers’ alpha as widely believed. Simplistic performance chasing best explains aggregate flows to the mutual fund space and flows across funds. These results hold for both actively managed and passive index funds. Empirical patterns commonly interpreted as reflecting learning about managerial skill also appear in falsification tests and are mechanical. Our results are consistent with the view that, on average, households are homo sapiens with limited financial sophistic...

Abstract We document that U.S. mutual funds with investment objectives designated as “Sustainable Investment Overall” by Morningstar (ESG funds) are more likely than other mutual funds to vote in support of environmental and social (ES) shareholder proposals and governance (G) shareholder proposals. We also find that the higher support for ES proposals by ESG funds relative to other funds is more pronounced in index funds than in active funds, consistent with trading constraints influencing voting behavior. While these results provide evidence that ESG funds “walk the talk” with their voting b...

A comprehensive analysis of the performance and flows of U S actively-managed equity mutual funds during the COVID-19 crisis of 2020 finds that the funds lost money during the crisis.

Using a comprehensive list of terrorist attacks over three decades, we find that aggregate investor risk aversion inversely relates to terrorist activity in the United States. A one standard deviation increase in the number of attacks each month leads to a $75.09 million drop in aggregate flows to equity funds and a $56.81 million increase to government bond funds. Tests on alternative channels further suggest that the shift in aggregate risk aversion is driven mainly by an emotional shock rather than changes in wealth or the outside environment. We also investigate possible alternate explanat...

Comparison of actively managed mutual funds in BRICS between 2011 and 2019 shows that green funds outperform their counterparts for the entire sample and within-country assessment, and proposes various interventions that could foster the adaptability of a carbon-neutral investment landscape.

This paper analyzes the effect of the Sustainable Finance Disclosure Regulation (SFDR) on mutual funds and individual investors in the EU. First, we study whether affected funds increase their sustainability compared to a control group. Second, we examine if the regulation makes individual investors allocate more capital into more sustainable funds. In a difference-in-differences setting, we analyze the influence of the regulation on ESG fund scores and fund net inflows. Our results show that affected funds increase their sustainability rating after the policy intervention. Additionally, we fi...

This study made it possible to evaluate the penetration rate of mutual health insurance in the Thiès region in 2023, but also to identify the factors associated with membership in a mutual health insurance.

Renewable energy sources have significant socio-economic benefits. Usually, the investment in such ventures is financed by the states. However, the growing scale warrants enhanced participation from financial markets. In this paper, we assess the attractiveness of renewable investments by comparing the performance of alternative energy-focused equity funds against their conventional counterparts. The sample spans over ten years from 2010 to 2019 and includes 3886 funds across nineteen Eurozone countries. Our findings suggest that renewable energy funds underperform traditional peers and market...

We study tradeoffs among active mutual funds’ characteristics. In both our equilibrium model and the data, funds with larger size, lower expense ratio, and higher turnover hold more-liquid portfolios. Portfolio liquidity, a concept introduced here, depends not only on the liquidity of the portfolio’s holdings but also on the portfolio’s diversification. We also confirm other model-predicted tradeoffs. Larger funds are cheaper. Larger and cheaper funds are less active, based on our new measure of activeness. Better-diversified funds hold less-liquid stocks; they are also larger and cheaper, and...

Abstract Hedge funds that endorse the United Nations Principles for Responsible Investment (PRI) underperform other hedge funds after adjusting for risk but attract greater investor flows, accumulate more assets, and harvest greater fee revenues. Consistent with an agency explanation, the underperformance is driven by PRI signatories with low environmental, social, and governance (ESG) exposures and is greater for hedge funds with poor incentive alignment. To address endogeneity, we exploit regulatory reforms that enhance stewardship and show that the ESG exposure and relative performance of s...
