Asian Tech Stocks Plunge as AI Jitters Hit Chipmakers

South Korean and Japanese stock markets fell sharply as a sell-off in technology shares, driven by AI-related concerns, hit chipmakers. South Korea's KOSPI dropped more than 4%, dipping below 8,000, prompting a halt in program selling. The decline followed a rout in US tech stocks that soured sentiment across Asia. The sell-off overshadowed positive economic news from Japan, where tax revenue reached a record 84.2 trillion yen and summer bonuses at major firms topped 1 million yen for the first time.
