A federal jury in California agreed with the SEC that a corporate official engaged in insider trading when he purchased securities of a company based on material nonpublic information (“MNPI”) about a different company. The April 5, 2024 verdict for the SEC in SEC v. Panuwat (N.D. Cal.) could embolden the SEC to pursue more claims of “shadow trading,” which involves trading the securities of a public company that is not the direct subject of the MNPI but whose stock price allegedly would be affected by that news.
