Jensen Huang, CEO of Nvidia, has sold nearly $500 million worth of shares this summer, with $322.7 million sold in July alone, just before a significant downturn in the tech sector. His sales were part of a pre-determined trading plan filed in March, allowing him to mitigate potential losses as Nvidia's stock faced a 20% decline amid broader market volatility. This downturn followed weak economic data and disappointing earnings from major tech companies, leading to increased investor concern over high valuations. Huang's sales, which have totaled $1.4 billion since 2020, reflect a trend among Nvidia insiders who have sold over $1 billion worth of shares this year. As a result of the stock decline, Huang's personal fortune has decreased to $89 billion, although he still retains a significant number of Nvidia shares. Despite the recent challenges, Nvidia remains a key player in the semiconductor industry, contributing to the infrastructure for the AI wave sweeping across the tech landscape.
