According to online reports, according to the Financial Times, in the past 12 months, NVDA.O insiders have sold more than US$1 billion in company shares. Trading volume has surged recently as executives cashed in on the artificial intelligence investment boom. More than $500 million of that stock was sold this month, just as the California chip design company's share price climbed to a record high. Investors have previously increased their holdings in Nvidia's shares, betting that demand for artificial intelligence chips will surge, making it the world's most valuable company. The stock price rise follows a turbulent year for Nvidia: Trade tensions and breakthroughs in AI in other countries threatened demand for its products. CEO Huang Renxun this week launched his first share sale since September last year. Nvidia said that all sales by Huang Renxun followed a predetermined trading plan established in March, which determined in advance the price and date to trigger the sale. Huang Renxun still owns most of his Nvidia shares. Ben Silverman, vice president of research at VerityData, commented: "When the stock price fell in the first quarter, he (Huang Renxun) did not sell, which was very wise. He waits for the stock price to recover to a more ideal selling price."
