Asymmetric Impact of Compliance Management Reform on Opportunistic Insider Trading

Full description

Using a sample of the listed state-owned enterprises (SOEs) in China, this study investigates the impact of the compliance management reform on opportunistic insider trading. The results show that the reform significantly constrains opportunistic insider selling by executives in SOEs, while having insignificant impact on insider purchases. Mechanism analyses suggest that the effect primarily operates through improvements in corporate governance quality and reductions in information asymmetry. Moreover, the inhibitory effect of compliance management is more pronounced among local SOEs, firms subject to weaker external oversight, those located in regions with underdeveloped institutional environments, and it primarily suppresses opportunistic insider selling by directors and senior management. Additional analysis indicates that compliance management significantly mitigates stock price crash risk and contributes to capital market stability. This study contributes to the literature on the determinants of opportunistic insider trading by highlighting the role of compliance management as an external governance mechanism. It also provides practical implications for policymakers aiming to integrate government regulation with internal compliance practices to promote the high-quality development of capital markets.
