Hang Seng Tech Index Drops 2.89% as Chinese AI and Semiconductor Stocks Plunge
The Hong Kong Hang Seng Tech Index fell 2.89% to its lowest level since late September 2024, driven by steep declines across major domestic technology sectors. Leading AI firms MiniMax and Zhipu fell over 13% and 7% respectively, while semiconductor companies like Biren Technology dropped over 11%. The sharp downturn reflects heightened market sensitivity regarding Chinese artificial intelligence developers and semiconductor chipmakers facing geopolitical pressures and execution risks. It illustrates how shifting investor sentiment can quickly erode market valuations across both AI software developers and critical hardware supply chain providers. Alongside AI firms and chipmakers such as SMIC (down over 6%) and Hua Hong Semiconductor (down over 9%), optical communication and printed circuit board (PCB) stocks also suffered significant losses. The main Hang Seng Index concurrently closed down 1.43%.
