Jen-Hsun Huang has launched a 10b5-1 plan to reduce his holdings, with a maximum of 6 million shares of Nvidia to be sold by the end of the year.

On June 24, Nvidia CEO Jensen Huang’s new 10b5-1 trading plan was officially launched, with plans to sell up to 6 million shares by the end of the year. Nvidia shares, which previously fell below $100 this spring, have rebounded 53% to close around $144 as of Monday. Huang sold 100,000 shares worth $14.4 million between Friday and Monday as part of a new 10b5-1 trading plan, according to the latest SEC filing. Huang’s preset stock trading plans were established in March under SEC Rule 10b5-1, which allows company insiders to sell shares at a predetermined time, even if they may then have material nonpublic information, and the plans are designed to protect executives from insider trading charges. Under the 10b5-1 plan, Huang could exercise 6 million options by the end of the year, which is worth about $865 million based on Monday’s closing price of $144. Billionaire Mark Stevens, a member of Nvidia’s board of directors, also began selling shares, selling more than 600,000 shares worth about $88 million on June 18, according to a separate SEC filing.
