Asian stock markets are experiencing significant declines, led by a sharp drop in South Korean stocks, which fell over 8%, triggering a circuit breaker. The sell-off comes in the wake of a substantial unwinding in AI-related trades and deteriorating market conditions following renewed tensions in the Middle East. Major tech firms like Samsung Electronics and Taiwan Semiconductor have reported steep losses, contributing to fears of an overheated stock rally. As investors seek to protect their portfolios, discussions about potential interest rate hikes by the Federal Reserve are amplifying concerns. The implications of this downturn could extend beyond Asia, with analysts pondering whether the Nasdaq will follow suit in the coming days.
