Pearl River Securities Stock Department Portfolio Expert Wu Xindi pointed out that the rapid rise in artificial intelligence infrastructure investment reflects an important strategic deployment, rather than optional growth projects. AI capabilities are increasingly becoming the core of competitiveness in cloud services, enterprise software, search, and consumer applications, driving continuous investment in the entire technology ecosystem. It is worth noting that many investors still underestimate the breadth of AI opportunities, especially in the Chinese market. Currently, the market focus is still on large internet platforms, but more attractive opportunities may exist in the upstream and deeper layers of the supply chain. Large-scale AI applications require a whole set of supporting technology ecosystems, including interconnection technology, optical communication, chip testing, and power infrastructure. As AI clusters need to transfer massive data quickly between chips and servers, the complexity of semiconductor testing continues to increase. In addition, AI data centers consume far more power than traditional computing environments, making these areas increasingly critical. These are not optional upgrades, but important building blocks in the process of AI popularization. This also means that investment opportunities are expanding from super large stocks with high index weights to a broader market range. Many upstream suppliers and infrastructure enablers are directly benefiting from this capital expenditure cycle; some companies have clearer paths to monetization, higher profit visibility, and more attractive valuations. Therefore, investors do not need to participate in AI growth only through the largest index constituents, but can also find relevant investment opportunities among a broader portfolio of companies.
