The Hang Seng Index rose 0.6 per cent to 23,482.58 by 9.33am. The Hang Seng Tech Index gained 1 per cent. Mainland China’s CSI 300 Index slipped 0.1 per cent. US stocks tumbled overnight, battered by sell-offs in technology stocks on growing concerns about the rapid pace of share price rises among AI-related stocks. The Nasdaq 100 index plunged 3.3 per cent. South Korea’s Kospi index was in focus in Asian trading amid elevated volatility. The gauge rebounded more than 4 per cent after a 10 per cent plunge on Tuesday that at one point triggered a circuit breaker. Japan’s Nikkei 225 was little changed. Earnings results from US memory chipmaker Micron Technology, due later on Wednesday, will take centre stage. They will offer investors a sense of whether artificial intelligence infrastructure buildouts remain robust enough to give fresh legs to the stock market.
