The Southern China GEM ETF (03147) rose more than 2%, tracking the performance of the Shenzhen Stock Exchange's ChiNext Index. By the time of writing, the ETF had climbed 2.09% to HK$15.15, with a turnover of HK$3.8244 million. On April 22, A-shares saw a broad-based rally, with the ChiNext Index closing at 3,752.76 points, marking a new 11-year high. Analysts pointed out that the recent strong rebound in the ChiNext Index is mainly driven by the improving prospects of its two largest weighted sectors—new energy and communications. The growth in the communications sector is primarily fueled by the construction of AI data centers. Over the past three years, the bottleneck in AI data center construction has been computing power chips. Beyond 2025, as large-scale AI computing clusters increasingly demand enhanced network interconnectivity (optical communication), optical modules and upstream optical chips are expected to become the new bottleneck. The optical module industry is projected to maintain strong demand through 2026.
