Abstract

During the COVID pandemic, the mobility of individuals is largely reduced. This paper is to investigate how this immobility-induced social isolation affects conference calls sentiment. We employ several exogenous events: first death via COVID in the county, declaration of State of Emergency, and Stay at Home Order. We find a consistent result that mobility constraints decrease the sentiment within earnings calls. Our findings suggest the variation of mobility constraints impacts manager mood and further influences short-term market returns beyond firm fundamentals. Our results remain significant after using alternative proxies for mobility constraints and focusing on the manager’s specific sentiment usage.
