Investment opportunities include four categories: (1) AIDC power supply mainframes such as PSU, HVDC, and SST, which have high value concentration and technical barriers; (2) Station-level energy storage, which is becoming a necessity for AI data center grid connection; (3) Core components, particularly solid-state circuit breakers, CBU/BBU, DC/DC devices, and electronic fuses/relays; (4) Third-generation semiconductors like GaN and SiC [2] Market Sentiment and Investment Trends - CICC noted that the "deposit into the market" effect may diminish by 2026. This effect emphasizes the importance of "new funds" while also considering "exit funds" to determine "net new funds," which have a stronger correlation with stock prices. The willingness of residents to enter the market is closely related to income expectations. Even when focusing on new funds, the growth rate of new funds is more closely related to stock market performance. The entry of high-net-worth individuals and insurance funds has provided significant support to the stock market in 2025, but this influence may wane in 2026 [3] AI Cloud Infrastructure - Open Source Securities reported that Amazon AWS announced a price increase of approximately 15% for its EC2 machine learning capacity blocks, marking the first break from its long-standing pricing tradition of only decreasing prices. This service model was introduced to address the supply-demand imbalance of high-performance GPU resources. The price increase confirms the high demand for AI computing resources globally and indicates that the scarcity of resources in the AI cloud industry may become more pronounced [4]
