On December 5, the three major A-share indices surged in the afternoon, with computing hardware performing strongly. CPO and copper cable high-speed connection sectors led the gains. As of 14:36, the ChiNext Artificial Intelligence ETF Hua Xia (159381), which has over 56% CPO content in optical modules and the lowest fees in its category, rose 1.19%, with daily turnover exceeding 300 million yuan. The 5G Communication ETF (515050) increased by 0.43%, and the Cloud Computing 50 ETF (516630) rose 0.52%.

On the news front, Bank of America estimates that by 2030, the market size for AI infrastructure will reach 800 billion yuan, with one-third of China's total AI capital expenditure allocated to this sector. Driven by computing power expansion and policy support, China's traditional advantageous industrial chains, such as power and manufacturing, are poised for revaluation.

Foreign investors are increasingly focusing on China's AI infrastructure sector. Macquarie analysts noted that China's AI infrastructure sector has lagged in recent years, but some sub-sectors are now rebounding, narrowing the valuation gap with related industries in U.S. stocks. If China accelerates its investment in AI, the gap between related targets and U.S. stocks is expected to close entirely. UBS economists stated that China already has a "moderately ahead" layout in new infrastructure. Under the "15th Five-Year Plan," infrastructure sectors serving large-scale AI applications, such as integrated computing networks and information communication networks, are expected to receive substantial industrial support.
