The Nasdaq 100 plunged more than 6pc on Thursday - the biggest fall since April 2025 - with shares in semiconductor makers the hardest hit. The downturn was the worst since Mr Trump's so-called "liberation day", when he rolled out tariffs to countries around the world. Investors fear the Democrats' midterm election victory will usher in tighter restrictions on AI companies, whose valuations have grown rapidly under Mr Trump. Nvidia, which is the world's most valuable listed company, fell by more than 6pc while rivals including $AMD+WL and Micron plummeted 13pc and 11pc, respectively.
