On the market, hot sectors performed prominently, and the comprehensive rebound of technology stocks became the main line of the market. The MicroLED concept set off a limit-up wave, with many stocks such as Jucan Optoelectronics, Huacan Optoelectronics, and Jufei Optoelectronics achieving “20CM” limit-ups. This was mainly driven by the rising demand for high-speed data center transmission brought about by the rise of generative AI. The MicroLED CPO solution, with its low energy consumption advantage, is expected to become an alternative optical interconnection solution, and the industry prosperity continues to improve.
The semiconductor industry chain strengthened across the board, with sub-sectors such as advanced packaging, lithography machines, and third-generation semiconductors rising simultaneously. Qiangyi Co., Ltd. achieved a “20CM” limit-up, and leading stocks such as North Huachuang and SMIC performed brightly. On the news front, many sub-sectors of the semiconductor industry chain have ushered in a price increase wave, coupled with the explosion of AI computing power demand, the industry prosperity cycle continues to rise.

Analysts said that the current A-Shares are still in a structural market. Driven by policy support and industrial upgrading in the technology field, relevant sub-sectors are expected to continue to attract capital attention, but short-term fluctuation risks need to be vigilant, and rational layout of high-quality targets is recommended.
