Chip Stocks Plunge Globally as AI Investment Concerns Rattle Markets

Major chip stocks experienced sharp declines across US and Asian markets, with South Korea's Kospi index dropping 8% and triggering a temporary trading halt on Tuesday. The sell-off reflects growing investor anxiety about valuations and returns in the AI sector, which has driven semiconductor demand but now faces questions about sustainability.

Why it matters: AI infrastructure investments depend on chip availability and pricing; market volatility signals potential shifts in enterprise spending priorities and hardware procurement plans.
