The effect of ownership structure on the price earnings ratio — returns anomaly

This is an author's peer-reviewed final manuscript, as accepted by the publisher.

This study investigates\ud how insider ownership affects this relation. We show that when insider ownership is high, returns\ud decline for low P/E firms and improve for high P/E firms. These findings are rationalized in the\ud context of entrenchment and alignment of incentive effects. For low P/E firms, low stock returns\ud reflect the inability of boards of directors and outside shareholders to influence poorly\ud performing entrenched management. For high P/E firms, boards of directors and outside\ud shareholders are less likely to intervene since higher returns reflect increased agency incentives\ud for value-creating managers
