According to Jin10, Asia's tech-heavy markets plunged Friday amid concerns about tighter regulatory scrutiny and slower AI infrastructure growth, triggering the biggest drop in U.S. stocks since the tariff-driven “Liberation Day” selloff a year and a half ago. South Korea's Kospi fell more than 8% at one point, triggering a circuit breaker, while Japan's Nikkei dropped nearly 7%. Market participants said chipmakers and data center equipment suppliers in South Korea and Japan were particularly vulnerable after their shares fell sharply on Wednesday and Thursday. Michael McCarthy, CEO of online brokerage Moomoo Australia and New Zealand, said market sentiment had shifted substantially and that sharp moves in either direction often accompany turning points marked by strong disagreement. He said the previous night's sharp selloff appeared to show the market moving in that direction. Nick Ferres, chief investment officer at Vantage Point, said semiconductor and memory stocks were expected to have a brutal day.
