Job Market Paper:

Correlated Signals and Career Concerns: Why do Mutual Funds Herd?    

Abstract: Mutual fund managers may herd in their trading decisions because they obtain similar information or because career concerns create incentives to maintain similar portfolios. I develop
a consistent and unifying framework to summarize trade-based and holding-based aspects of
common portfolio evolution at the fund level. Herd behavior is strongest among fund managers
with short tenure. Funds that herd underperform other funds with more independent trades
and holdings. These results suggest that managerial career concerns are an important driver of
herd behavior.
