The Shanghai Composite rose 0.7% to close at 3,917, while Shenzhen Component 1.5% to 13,333 on Monday, with mainland stocks extending a four-session rally to a two-week high on steady fund inflows and news of a planned free-trade port in Hainan. Data showed China’s private fund sector expanded to a record 22.1 trillion yuan in November, reflecting continued investment into equities. Sentiment was further lifted after authorities formally began operations at the Hainan Free Trade Port, underscoring Beijing’s push to open up the economy. Hainan-related shares including China Tourism Group Duty Free, Hainan Airlines, Hainan Airport Infrastructure, and Hainan Strait Shipping, all hit their 10% daily limit. Technology shares also led the broader market, such as Eoptolink (+6.9%) and Zhongji Innolight (+5.5%). Conversely, banks and industrial stocks fell, while BOE Technology lost 0.7%, after US lawmakers called for its inclusion on a Pentagon list of firms linked to the Chinese military.
