[Epic sell-off in U.S. stocks. The wealth of the top five richest people has shrunk by US$150 billion in a single day. Musk alone lost nearly US$100 billion] November 6th, US stocks suffered a sharp sell-off on Thursday, and technology stocks became the hardest hit area. During the session, the Dow Jones Industrial Average, the S&P 500 Index and the Nasdaq Composite Index saw their maximum declines reach 2.38%, 3.57% and 5.35% respectively. The Philadelphia Semiconductor Index's decline once expanded to 11.6%, and the AI ​​hardware industry chain suffered concentrated selling. NVIDIA once fell 9%, and TSMC, SpaceX, and Tesla once fell 11%. Forbes' real-time billionaire rankings show that the decline in U.S. stocks has caused the net worth of many technology tycoons around the world to shrink significantly. Elon Musk's net worth dropped by US$91.2 billion in a single day, a drop of 10.50%; Dell Technologies founder Michael Dell lost US$20.5 billion, a drop of 9.60%; Nvidia CEO Jensen Huang lost US$15.1 billion, a drop of 8.70%; Oracle founder Larry Ellison lost US$13.2 billion, a drop of 8.05%; Meta founder Mark Zuckerberg lost US$12.9 billion, a drop of 5.98%. The total net worth of the above-mentioned five rich people has shrunk by US$152.9 billion in a single day. Among them, the decrease in the value of Musk alone accounted for nearly 60% of the total losses of the five people. This wealth shrinkage mainly reflects the impact of the decline in the stock prices of relevant listed companies on the valuation of the wealthy holdings.
