We examine how in-person and virtual interactions shape mutual fund investment decisions using a comprehensive dataset of corporate site visits. Before COVID-19, fund pairs jointly attending in-person visits trade more similarly (by 20% of a standard deviation) than matched controls. The effect holds for stocks unrelated to the hosting firm and appears in firm-level, industry, geographic, and asset allocation decisions; it is stronger among managers with prior familiarity, similar seniority, and mixed gender. Stocks purchased by jointly visiting funds earn higher subsequent returns, indicating that these exchanges convey valuable information. Exploiting the exogenous shift to virtual communication induced by COVID-19, we find that in-person visits remain associated with correlated trading during the pandemic, whereas virtual visits have substantially weaker effects. A survey of fund managers confirms that site visits prompt information exchange, follow-up research, and portfolio adjustments. In-person interactions appear central to information acquisition; and virtual interactions do not easily replicate this function.

We analyze over 27,000 social media livestreams by Chinese mutual funds to investigate whether they achieve regulators’ goal of improving retail investment decisions. Our findings indicate that livestreams generate significant inflows, often within minutes of their start times. Yet rather than educating investors, livestreams amplify return-chasing behavior and predict sharp declines in fund performance. Investors who buy in response to livestreams would earn higher returns by holding index funds or even cash. Further analyses using deep learning algorithms reveal that livestreams are more persuasive when speakers are more physically attractive, use more positive language, and sound more excited. We conclude that livestreams primarily function as persuasive advertising and that regulators should be wary of educational efforts led by sellers of consumer financial products. We also conclude that prior evidence on the benefits of firms’ social media use in equity markets does not extend to financial product markets in this setting.

This study investigates the impact of non-punitive regulation on stock price crash risk. We use the inquiry letter issued by the Shanghai Stock Exchange (SSE) and the Shenzhen Stock Exchange (SZSE) in China as a proxy for non-punitive regulation. The results demonstrate that stock price crash risk decreases after the issuance of the inquiry letter. The reduction in crash risk is more pronounced for firms receiving a more detailed inquiry letter (or an inquiry letter requiring intermediary agencies to provide professional opinions) and for those that have more incentives or are more easily able to conceal bad news. The firm's response to the corresponding inquiry letter reduces crash risk. Furthermore, the impact of the inquiry letter on reducing crash risk is short-term, not long-term. These results indicate that the inquiry letter reduces crash risk by playing its information discovery role.
