Summary
Asian stock markets saw a sharp decline on Friday, with Tokyo's Nikkei 225 dropping 5% and Taiwanese markets falling over 5% as investors offloaded shares in the artificial intelligence and chipmaking sectors. The sell-off is driven by growing concerns over the sustainability of AI valuations and whether the intense demand for computing hardware will yield the long-term profit and productivity gains initially projected. These regional losses follow a broader downturn on Wall Street, where the S&P 500, Dow Jones, and Nasdaq all registered declines despite generally positive corporate earnings reports released during the latest quarter.
