Hong Kong stocks rebounded on Monday after four consecutive declines, with the Hang Seng Index closing at 25,453.23, up 336.38 points or 1.34%, and the Hang Seng Tech Index rising 1.58% as turnover expanded to HK$210.77 billion. The advance was led by artificial intelligence computing power, semiconductors and related hardware, after SMIC and Hua Hong Semiconductor posted second-quarter results that beat market expectations and optimism grew around memory demand. SMIC closed up 6.14%, Hua Hong rose more than 7% intraday, and Montage Technology gained more than 9%. Optical communications and PCB shares also rallied on AI data-center demand, with YOFC surging 12.1% and Kingboard Laminates jumping 9.12% after guiding first-half net profit growth of more than 200%. Chinese internet stocks broadly advanced, SenseTime spiked nearly 11% intraday after guiding to its first-ever consolidated profitability, and shipping, gold miners and major financials also gained, while Lenovo and biopharmaceutical B-class shares lagged. Analysts at Huatai Securities and CITIC Securities said Hong Kong stocks are in a volatile bottoming phase, with the AI supply chain, wafer foundries and intelligent computing infrastructure seen as areas of continued support.
