The expansion of domestic semiconductors and the certainty of domestic computing power construction are not affected by short-term overseas macro disturbances, occupying the C position. Overseas computing power is being salvaged. Macro panic is temporarily still a buying point for technology, but the rebound exceeding expectations reflects the market's extreme fear of missing out. Geopolitically, Israel is on high alert, and Iran plans to implement control over the submarine cables in the Strait. \[Macro\] Israel: The military has entered the highest level of alert. Iran: Based on its sovereignty over the seabed and subsoil of its territorial waters, it will implement management measures such as licensing, supervision, and charging for submarine cables passing through the Strait of Hormuz.

Models: Gemini 3.5 Pro will be launched next month, priced 30 times higher than 1.5. Hardware Bottlenecks: Lumentum emphasizes that indium phosphide is the core bottleneck, with an imbalance in supply and demand for EML (electro-absorption modulated laser) exceeding 30%; 3.2T may need to revert to the EML solution due to noise characteristics. AMD's Lisa Su: The development of AI has given rise to a new positioning for CPUs, with the ratio of CPU to GPU expected to become 1:1. Domestic Computing Power: China's Computing Power Platform (Beijing) has officially launched, featuring core functions for computing power situational awareness monitoring and supply-demand matching. It is required that the localization rate for major projects included in the computing power network list be ≥80%. Industry Chain: Dongshan has revised its chip expansion plan, with optical module orders expected to reach 30 million units, and sellers have raised their targets to 700 billion. Calendar: The Kunpeng Ascend Developer Conference will be held on May 22-23. Related ETFs: Cloud Computing ETF (159890), ChiNext Artificial Intelligence ETF (159243) \[Semi-conductors\] Yangtze Memory Technologies: Completed IPO (Initial Public Offering) guidance filing. Related ETF: Semiconductor Equipment ETF (561980) \[New Energy & Lithium Batteries\] Lithium Mines: Bald Hill lithium mine is resuming production, with shipments scheduled for the third and fourth quarters of 2026; combined with the simultaneous resumption of Core mines, the space for low-priced Australian lithium mines to resume production is basically cleared, with limited new supply increments. Seller's View: The decline in leading production scheduling and industry prices in May does not represent an industry trend; it is merely an issue of inventory rhythm in the interim. Related ETFs: New Energy Vehicle ETF (159183), Battery ETF (561910) \[Nonferrous Metals\] Aluminum: Citigroup expects aluminum prices to rise to $4,000/ton within the next three months, with an average price potentially reaching $5,350 in a bullish scenario by 2027. Nickel: Indonesia has suspended operations for over 50 mining companies, including 34 nickel mining projects Related ETFs: Non-ferrous Metals Mining ETF (159690) 【Strategy Observation】 Market Performance: Yesterday's trading volume was 2.89 trillion, a decrease of 7.4 billion. The index dipped below the 20-day moving average but held its ground, with a significant rise in the STAR Market—clear industrial trends + emotional support, certainty in domestic and international tech demand exploded, and funding costs were overshadowed by long-term yield expectations. Sectors and Themes: Leading Directions: Utilities (computing power synergy + domestic computing network construction), Electronics (semiconductors + computing power), Computers (domestic computing power construction). Domestic Semiconductor Expansion + Domestic Computing Power Construction: Extremely high certainty, unaffected by short-term overseas macro disturbances, occupying the C position. Overseas Computing Power: Selectively being salvaged. Various Small Stocks: Taking advantage of active sentiment. Operational Thoughts: Macroeconomic panic is still a temporary buying point for technology, but the rebound exceeded expectations, reflecting the market's extreme fear of missing out. It is not difficult to predict buying technology on dips; maintain flexible positions, focusing on domestic computing power, semiconductor expansion, and indium phosphide and other hardcore directions.
