Semiconductor stocks slide, Philadelphia chip index in focus
Original: フィラデルフィア半導体株指数
US semiconductor stocks fell sharply, dragging the Philadelphia Semiconductor Index lower, after reports that US regulators are examining OpenAI. In Asia, Samsung Electronics and SK Hynix dropped 8-10% in Seoul on what Korean media called a 'Black Tuesday', while Japanese markets also saw selling pressure in chip and AI-related shares. Investors are watching whether the pullback in AI-linked stocks extends further.
Why now: A sharp global selloff in semiconductor and AI stocks triggered by US regulatory reports over OpenAI is moving markets worldwide.
