Social interactions and mutual fund portfolios: the role of alumni networks in China

PurposeThis paper aims to investigate the influence of social interactions on mutual fund portfolios from the perspective of alumni network in China.Design/methodology/approachBased on a data set that consists of 162 actively managed equity funds in China during the time period of 2003–2014, this study employs multiple linear regression model to control for organization- and location-based interpersonal connections as well as other confounding factors and clarify the causality relationship between alumni networks of mutual fund managers and their portfolios.FindingsAfter controlling for organization- and location-based interpersonal connections, we find that mutual fund managers who graduated from the same college/university have more similar stock holdings and are more likely to buy or sell the same stocks contemporaneously. As a result, alumni managers exhibit a higher correlation of fund returns. Moreover, the effect of alumni relationship on mutual fund investments becomes weaker when more managers are connected within the network. We also find that valuable information is shared among alumni managers: (1) the average returns for the alumni common holdings portfolios is significantly higher than those for non-alumni holdings portfolios and (2) a long-short strategy composed of stocks purchased minus sold by alumni managers yields positive and significant risk-adjusted returns.Practical implicationsThe findings suggest that information dissemination among connected fund managers could be one of the driving forces for mutual fund herding behavior, and that a portfolio of funds whose managers are educationally connected could be highly exposed to certain stocks and risks.Originality/valueThis paper contributes to the growing finance literature addressing the influence of personal connections on information dissemination that specifically contributes to price formation. It corresponds more closely to Cohen et al. (2008), who investigate college alumni connections between fund managers and corporate board members. Since the authors simultaneously examine three potentially overlapped social networks, which are based on education, locality and fund family, the authors are able to disentangle their effects on fund managers' investment decisions. Moreover, the findings suggest that institutional investors make investment decisions based on share private information, and therefore, it also contributes to the literature on fund herding behaviors (Grinblatt et al., 1995; Wermers, 1999).

Managers’ skills and fund flows in the Japanese mutual fund market

Purpose Mutual fund investors assess a fund manager’s skills when allocating their capital. To identify the rationale behind retail investors’ decisions, this study aims to examine the relation between mutual fund flows and abnormal returns (alpha), as well as the various risk factors in the Japanese mutual fund market, which has distinctive characteristics regarding investors and distributors. Design/methodology/approach Six standard asset pricing models are used to investigate how investors assess mutual fund managers’ skills: the market-adjusted return, the capital asset pricing model and the Fama–French three-factor model and its augmented versions. Findings Contrary to the literature, this study finds that investors in Japan mainly rely on alpha to assess mutual funds. In particular, investors respond to alpha for fund inflows and their evaluations depend on the market environment and their mutual fund search costs. Originality/value This study measures the response of investors to the skills of mutual fund managers in the Japanese market – especially for funds purchased through bank-related distributors that have aimed to capture inexperienced retail investors since deregulation in the 1990s – and reveals their high response to alpha.

An Empirical Investigation of the Performance of Fund Managers in Pakistan

This study aims to determine the stock selection ability and market timing ability of mutual fund managers, focusing on conventional funds and Islamic funds in Pakistan. Although there has been significant growth in the number and assets of mutual funds in recent years, few studies measure the performance of mutual funds managers. The scarcity of existing literature motivates this study. In this study, two models are used to measure the stock selection and market timing on a sample of conventional mutual funds and Islamic mutual funds over 2010 and 2019 using annual returns. Overall, the results indicate that the performance study of conventional mutual funds and Islamic mutual funds indicates that manager performance is not superior in all three portfolios, i.e., conventional funds, Islamic funds, and overall funds in over sample period. This also indicates that both Conventional and Islamic fund managers do not outperform the market (KSE 100 index). Thus, there is a lack of market timing ability. Using Tranoy and mazuy and Jansen models found a lack of stock selection and market timing ability of mutual fund managers in Pakistani mutual funds. In this study, I have applied only two models to examine both the timing and selection ability of conventional and Islamic Pakistani equity funds. For future possibilities, the study suggests adopting several methods and approaches like the TMFF3 model and HM-FF3 model, making the study more comprehensive and accurate than this research.

Managerial behavior in fund tournaments—the impact of TrueSkill

Measuring mutual fund managers’ skills by Microsoft’s TrueSkill algorithm, we find highly skilled managers to behave self-confident resulting in higher risk-taking in the second half of the year compared to less skilled managers. Introducing the TrueSkill algorithm, which is widely used in the e-sports community, to this branch of literature, we can replicate previous findings and theories suggesting overconfidence for mid-years winners.

Efficient Market Managers

We examine the effect of the Efficient Market Hypothesis (EMH) on the investment behavior of mutual fund managers. We show that managers who are more likely to be exposed to the ideas of EMH throughout their higher education are more “passive” than their unexposed peers: they are more likely to manage index funds, and when managing active funds, they hold portfolios with larger numbers of stocks and deviate less from their investment benchmarks. Exposed managers, however, take more systematic risks. Although academic exposure to the EMH does not result in better performance, it helps professional investors generate capital inflows.

Integrating ESG factors in investment decisions by mutual fund managers: a case of selected Johannesburg Stock Exchange-listed companies

This paper examines whether mutual fund managers incorporate environmental, social, and governance (ESG) factors when deciding which sector to invest on behalf of their trustees. In doing this, the top 20 South African mutual fund companies (asset managers) listed on the Johannesburg Stock Exchange (JSE) were selected. The paper identified the top 30 JSE listed companies (in the large industrial, equipment, and machinery sectors, excluding unlisted and service-oriented companies) where trustees’ funds were invested (with a total of 28 companies between 2007 and 2017) from the mutual fund companies’ Equity Fund Fact Sheets 2017 (representing recent investment focus). ESG data were collected from the integrated and sustainability reports at the sampled companies’ websites, and financial data were sourced from the IRESS database. This study adopted the panel data analysis. The results show an insignificant negative relationship between the ESG proxies (water usage, employee health and safety cost [number of work-related fatalities], percentage of women on corporate board) and return on equity (ROE). This means that the sampled companies disregard the United Nations Principle of Responsible Investment (UN PRI) guideline, suggesting that asset managers focus on increasing returns on shareholders’ investment without considering ESG issues. The paper concludes that the disregard for responsible investment guidelines does not encourage companies to improve their unsustainable business practices.
