Great Wall Securities believes that the continuous rollout of AI applications will further accelerate the construction of computing infrastructure and edge-side computing facilities. Therefore, they remain optimistic about investment opportunities in related industrial chains. First, sectors such as optical modules, PCBs, main equipment suppliers, and copper cables—represented by the AIDC industrial chain—serve as fundamental support for computing power. With rapidly increasing demand, these sectors are experiencing both earnings growth and valuation expansion, presenting a double boost. Investors are advised to keep a close watch.
CMB Securities noted that 2025 is a standout year for optical module suppliers with high AI business exposure, as major players achieved significant revenue growth and margin expansion. Driven by sustained AI infrastructure investment cycles and ongoing upgrades to higher-value solutions, this strong performance is expected to continue into 2026 and beyond.
To capture core opportunities in computing power and AI applications, investors are advised to focus on the first ChiNext AI ETF (159363) and its off-exchange counterparts (Class A: 023407, Class C: 023408). The underlying index heavily weights leading optical module stocks, with over 56% exposure to the sector. In terms of sector allocation, more than 70% is allocated to computing power, while over 20% is invested in AI applications, enabling efficient exposure to AI-themed market trends.
