Strategic Disclosure of 10b5-1 Trading Plans

Abstract:     
We investigate whether increased legal protection arising from the voluntary disclosure of insiders’ Rule 10b5-1 trading plans enhances insiders’ strategic trade opportunities. Consistent with expected incremental legal benefits arising from disclosure, we find evidence that voluntary disclosure of 10b5-1 trading information increases with firm litigation risk, insider strategic trade potential, and institutional owner and analyst disclosure demands. In addition, consistent with enhanced strategic insider trade arising from the reduced litigation risk, we find greater insider trade returns for firms voluntarily disclosing 10b5-1 trading plans, especially for firms disclosing specific plan details. These findings extend prior research investigating the links between voluntary disclosure, litigation risk, and insider trading by providing evidence that voluntary disclosure—which potentially reduces information asymmetries—creates legal cover for greater strategic trade by insiders. These findings should also have important implications for courts and regulators, suggesting that 10b5-1 participation does not inherently indicate lack of scienter, and that mandating disclosure of 10b5-1 participation may not mitigate strategic behavior.
