The Shanghai Composite edged 0.1% higher to close at 3,920, while the Shenzhen Component gained 0.3% to 13,369 on Tuesday, as mainland stocks extended a five-session winning streak to a fresh two-week high led by strength in technology and non-ferrous metals shares. Non-ferrous metals drove much of the advance, with Shandong Gold jumping nearly 7%, as investors responded positively to China’s housing policy conference, where authorities pledged city-specific measures to curb new supply, reduce inventories, and improve the market mix to stabilise the real estate market. Local technology stocks also benefited from renewed optimism in the semiconductor sector after reports that US tech giant Nvidia plans to begin shipping its second-most powerful AI chips to Chinese clients ahead of the Lunar New Year. Top performers included Foxconn Industrial (+4%), NAURA (+4%), Cambricon Technologies (+3.4%), Contemporary Amperex (+1.7%), and Zhongji Innolight (+1.1%).
