Asia-Pacific and broader emerging-market equities weakened across June 4-5, with losses intensifying in South Korea on June 5 as semiconductor stocks sold off. South Korea’s KOSPI opened down 372.6 points, or 4.31%, at 8,266.81, later fell more than 5% to trigger an intraday circuit breaker, and was reported down over 5.5%, over 6%, and as much as 7% intraday in subsequent updates. The MSCI Emerging Markets Index fell 1.7% to 1,728.66 in a third straight day of declines. Japan’s Nikkei 225 also dropped sharply, while China’s ChiNext Index fell more than 3% and Shanghai slipped about 0.7%. Samsung Electronics, SK Hynix and SoftBank were among notable decliners. Reports linked the selloff to weaker-than-expected AI guidance from Broadcom and a circulating research note about Nvidia Rubin memory cuts.
