Is insider trading politically informative?

This study examines whether insider trading is politically informative and presents some evidence to hedge against firm-level political risk. Using quarterly data on U.S. listed firms from 2002 to 2021, we find that managers increase opportunistic insider sales prior to rises in firm-level political risk, while insider purchases show no significant change. Moreover, net opportunistic insider sales are positively associated with subsequent increases in a firm's political risk. These effects are more pronounced in firms with limited political connections, weaker innovation capability, and higher financial leverage, suggesting that political ties, innovation capability, and a sound financial structure serve as effective buffers against political risk. Our main results withstand a battery of robustness and endogeneity tests. Overall, our findings suggest that insider trading is politically informative, offering valuable insights for academics, regulators, and investors in interpreting such activities.

Abstract

This study examines whether insider trading is politically informative and presents some evidence to hedge against firm-level political risk. Using quarterly data on U.S. listed firms from 2002 to 2021, we find that managers increase opportunistic insider sales prior to rises in firm-level political risk, while insider purchases show no significant change. Moreover, net opportunistic insider sales are positively associated with subsequent increases in a firm's political risk. These effects are more pronounced in firms with limited political connections, weaker innovation capability, and higher financial leverage, suggesting that political ties, innovation capability, and a sound financial structure serve as effective buffers against political risk. Our main results withstand a battery of robustness and endogeneity tests. Overall, our findings suggest that insider trading is politically informative, offering valuable insights for academics, regulators, and investors in interpreting such activities.
