How do insider trading incentives shape nonfinancial disclosures? Evidence from product and business expansion disclosures
研究发现经理人会策略性地操纵产品和业务扩张的非财务信息披露时机与选择性，在买入股票前披露坏消息、卖出前披露好消息，以最大化交易利润。
Abstract Nonfinancial disclosures of product and business expansion planning occur frequently in practice and are an important vehicle by which managers convey corporate information to outsiders. However, little is known about how the opportunistic incentives of managers affect the choice of such nonfinancial disclosures. This study examines whether managers make their nonfinancial disclosures strategically for self-serving trading incentives. I find strong and robust evidence to suggest that managers manipulate the timing and selectivity of their nonfinancial disclosures in an attempt to maximize trading profits. Specifically, managers tend to disclose bad (good) news on products or business expansion before purchasing (selling) shares. I also find that such strategic behavior is more evident when the expected price impact of the disclosures is greater and when the CEOs are more powerful. However, I do not find evidence that the strategic behavior is weaker for firms with high institutional stock ownership. Overall, my results contribute to understanding managers’ strategic use of nonfinancial disclosures in fulfilling personal trading incentives, and should be of interest to boards of directors charged with the responsibility of monitoring and restricting opportunistic managerial disclosures and insider trades.
