Don't Take Their Word for It: The Misclassification of Bond Mutual Funds

Journal of Finance 2021 76(4), 1699-1730 open access
We provide evidence that bond fund managers misclassify their holdings, and that these misclassifications have a real and significant impact on investor capital flows. The problem is widespread, resulting in up to 31.4% of funds being misclassified with safer profiles, compared to their true, publicly reported holdings. “Misclassified funds”—those that hold risky bonds but claim to hold safer bonds—appear to on‐average outperform lower risk funds in their peer groups. Within category groups, misclassified funds receive more Morningstar stars and higher investor flows. However, when we correctly classify them based on actual risk, these funds are mediocre performers.

Resident Networks and Corporate Connections: Evidence from World War II Internment Camps

Journal of Finance 2017 72(1), 207-248
Using customs and port authority data, we show that firms are significantly more likely to trade with countries that have a large resident population near their firm headquarters, and that these connected trades are their most valuable international trades. Using the formation of World War II Japanese internment camps to isolate exogenous shocks to local ethnic populations, we identify a causal link between local networks and firm trade. Firms are also more likely to acquire target firms, and report increased segment sales, in connected countries. Our results point to a surprisingly large role of immigrants as economic conduits for firms.

IQ from IP: Simplifying search in portfolio choice

Journal of Financial Economics 2020 138(1), 118-137 open access
Using a novel database that tracks web traffic on the Security Exchange Commission's EDGAR server between 2004 and 2015, we show that institutional investors gather information on a very particular subset of firms and insiders, and their surveillance is very persistent over time. This tracking behavior has powerful implications for their portfolio choice and its information content. An institution that downloaded an insider trading filing by a given firm last quarter increases its likelihood of downloading an insider trading filing on the same firm by more than 41.3 percentage points this quarter. Moreover, the average tracked stock that an institution buys generates annualized alphas of over 12% relative to the purchase of an average non tracked stock. We find that institutional managers tend to track top executives and to share educational and locational commonalities with the specific insiders they choose to follow. Collectively, our results suggest that the information in tracked trades is important for fundamental firm value and is only revealed following the information-rich dual trading by insiders and linked institutions.
