内容摘要：

We test the impact of a pre-trade disclosure regulation in China, which requires corporate insiders to disclose their stock sale (but not stock purchase) plans prior to trade execution, on insider trading and stock market efficiency. The regulation significantly reduces information-driven insider sales. The stock market reacts negatively to observed insider stock sale plans, leading to a higher likelihood of insiders’canceling such stock sale plans. Despite the reduction of informed insider sales, stock price informativeness actually increases following the regulation, partially due to increased analyst following in stocks with negative future performance.
