China Galaxy pointed out that against the backdrop of the external environment, supply chain security and independent controllability remain long-term trends. Equipment and materials have the strongest logic under the top-level design of domestic innovation. Digital chips are the core carriers of computing power autonomy, and advanced packaging and testing benefit from technological upgrades. Soochow Securities stated that driven by AI, domestic computing power is developing rapidly. They are optimistic about domestic equipment manufacturers benefiting from the release of DeepSeek V4, which is equipped with a domestic computing power base. Institutions believe that the future may see the integration of the industrial chain from "large models - domestic AI chips - semiconductor manufacturing." The rapid development of domestic computing power, driven by AI, is generating new demand for advanced processes and advanced packaging and testing equipment. Both advanced logic and advanced capacity expansions by companies like ChangXin and Yangtze Memory Technologies are actively proceeding.
Looking ahead to the post-holiday market, brokerage strategy reports suggest that A-shares are likely to continue a震荡偏强 (volatile but relatively strong) operating pattern in May. On one hand, overseas tech stocks have reported better-than-expected earnings with密集催化 (frequent industrial catalysts). On the other hand, first-quarter reports show overall improvement in A-share performance but a divergence in景气度 (prosperity levels). The AI industrial chain and the resource and energy sectors remain the two directions with high景气度 (prosperity). Subsequently, technology and growth stocks are expected to continue consolidating their position as the market's core主线 (main theme).
