Internet reports that according to documents filed with the U.S. Securities and Exchange Commission, on Friday (July 18), when Nvidia's share price once again hit a record high, Nvidia CEO Huang Renxun also decisively stepped in and reduced his holdings of 75,000 shares again, worth approximately US$12.94 million. As early as March this year, Huang Renxun disclosed plans to reduce the holdings of 6 million Nvidia shares in accordance with rule 10b5 -1, and Friday's reduction was part of this plan. The 10b5 -1 trading plan allows insiders of a listed company to decide in advance to sell a specified number of shares at a predetermined time. The purpose of this plan is to avoid suspicion of insider trading and ensure transparency and fairness of transactions. Since last month, Huang Renxun has started his current round of sales reductions, and earlier this week, according to another SEC document, Huang Renxun had sold 225,000 shares of Nvidia shares, totaling approximately $37 million.
