The Southbound Growth Enterprise Market (03147) rose more than 2%, with the ETF tracking the performance of the Shenzhen Stock Exchange Growth Enterprise Index. As of the time of writing, it was up by 2.09%, closing at HK$15.15, with a turnover of HK$3.8244 million. On the news front, on April 22nd, A-shares rose across the board, with the Growth Enterprise Index closing at 3752.76 points, hitting an 11-year high. Analysis pointed out that the recent rebound of the Growth Enterprise Index was driven mainly by the upturn in the two largest weight industries (new energy and communication). The upturn in the communication industry is mainly driven by the construction of AI data centers. In the past three years, the bottleneck of AI data center construction has been in the computing chip. After 2025, the demand for network interconnection (optical communication) by large-scale AI computing clusters is increasing, and optical modules and upstream optical chips have become bottlenecks for AI data center construction. The optical module industry is expected to continue to see strong demand in 2026.
