Asian tech-heavy markets tumbled sharply on Friday, November 6, as concerns over tightening regulatory scrutiny and a slowdown in AI infrastructure spending triggered the steepest U.S. stock selloff since the tariff-driven "Liberation Day" crash a year and a half ago. South Korea's KOSPI plunged more than 8% at one point, triggering a circuit breaker, while the Nikkei fell nearly 7% intraday. Market participants believe chipmakers and data center equipment suppliers in markets such as South Korea and Japan are particularly vulnerable, with related shares already falling sharply on Wednesday and Thursday. Michael McCarthy, CEO of online brokerage Moomoo Australia and New Zealand, said market sentiment has undergone a substantive shift, and turning points are often accompanied by strong disagreement and reflected in violent fluctuations—which appears to be exactly the case now; last night's fierce selloff indicates the market is moving in that direction. Nick Ferres, Chief Investment Officer at Vantage Point, said semiconductor and memory stocks are in for a brutal day.
