Since the beginning of this year, internal personnel at nvidia have cashed out over $1.8 billion in the stock market, and there may be further selling actions. According to data compiled by Washington Service, nvidia executives and directors reduced their shareholding by nearly 11 million shares in 2024, the most reduction since at least 2020 after considering the impact of stock splits, but their proportion in nvidia's 24.5 billion shares outstanding is negligible. The delay in shipping the Blackwell chip by nvidia has made investors nervous, and the high investment by tech companies in ai also raises market concerns about how long it can be sustained. The selling by internal personnel is not yet over. CEO Huang Renxun recently completed a plan to sell 6 million shares, and director Mark Stevens, who has already sold 1.6 million shares this year, disclosed a plan to sell another 3 million shares.
