Changes in US stocks | Most star tech stocks fell, Oracle (ORCL.US) fell more than 3%

The Zhitong Finance App learned that on Friday, the decline in the NASDAQ index widened to 1.2%, and most star technology stocks fell. As of press release, Broadcom (AVGO.US) lost more than 10%, Micron Technology (MU.US) fell more than 5%, Oracle (ORCL.US) and AMD (AMD.US) fell more than 3%, TSM.US (TSM.US) fell 2.6%, Amazon (AMZN.US) fell more than 1%, and Meta (META.US) fell more than 0.8%. According to the news, the US Supreme Court is about to rule on the legality of the comprehensive tariffs introduced by Trump in April. This may be the next test for the stock market, which has been making great strides recently. This ruling once caused the global market to plummet. The S&P 500 index has rebounded 39% since its low that month and closed at a record high on Thursday, partly because tariffs were ultimately lower than Trump's previous threat, while the boom in artificial intelligence investment and continued rapid growth in the US economy provided support. If the US Supreme Court rules that Trump's approach to comprehensive tariffs exceeds its authority, there is still great uncertainty about the future. A ruling is less likely to be handed down this year. The court held its last public hearing of the year on Wednesday, and the next one will wait until January 9 next year. Ohsung Kwon, chief stock strategist at Wells Fargo Bank, estimated in October that if the tariffs are ruled invalid, the earnings of S&P 500 companies before interest and taxes will increase 2.4% from this year's level by 2026.
