China and Hong Kong stocks opened lower on Monday, tracking regional peers as investors grew concerned over the sustainability of the AI rally after strong U.S. jobs data fuelled ‌fears ⁠of ⁠Federal Reserve rate hikes. China's blue-chip CSI300 Index opened 2.4% lower, while the Shanghai Composite Index was down 2.2%. Hong Kong's benchmark Hang Seng opened 1.5% lower. The tech rally in China has been driven largely ⁠by the ‌chip supply chain, closely mirroring performances in global stocks such as Micron ⁠and Nvidia. Shares of Zhongji Innolight, an Nvidia supplier of optical components and a bellwether for China's AI rally, fell 4% at market open. The company has recently overtaken CATL as the biggest weight in China's CSI300 ‌benchmark. The tech-focused STAR50 Index opened 4.8% lower, while onshore semiconductor shares slumped more than 5%. Wall Street's ⁠nine-week winning streak ended with a thud on Friday, as red-hot technology stocks suffered their largest daily decline since April 2025 after a hot jobs report fuelled fears of a hawkish policy pivot from the U.S. central bank.
