The semiconductor equipment ETF index (561980) opened nearly 2% higher in the morning and rose 0.93% as of the time of writing. Cambricon rose over 5%, KFMI rose over 10%, Jianghua Microelectronics rose over 7%, and companies like Yake Technology and China Shipbuilding Gas rose over 3%. Multiple stocks including SMIC, Tuojing Technology, Haiguang Information, and Zhongke Feicai also saw increases. Data shows that after a pullback over the previous two trading days, the CSI Semiconductor Industry Index's year-to-date increase has fallen to 44%, having previously risen over 70%. The sector exhibits characteristics of high prosperity, high volatility, and high crowding. As of June 1, this index has cumulatively risen over 375% since 2020 and over 136% since 2025, ranking first among similar indices in the sci-tech chip and semiconductor materials and equipment sectors. According to the proposed semi-annual adjustment list for the index, it plans to include four newly added semiconductor equipment and materials companies: SEMITRONIX, Silan Microelectronics, Xingfu Electronics, and Pioneer Precision. All of these are relatively new listings, reflecting the index's further strengthening of its "hard technology" attributes. At the same time, the index plans to remove MTCN, Sanjia Technology, Jingsheng Shares, and Aisen Shares from its portfolio. Galaxy Securities pointed out that recently, global technology assets have shown a pattern of fluctuating differentiation. The semiconductor sector, which previously led the market, has ended its continuous strong performance, while the U.S. stock market has shown strong resilience. Overall, this round of adjustment does not indicate a change in the logic of the technology industry but rather reflects the market's phase of valuation digestion and position rebalancing after a rapid rise. In terms of industrial catalysts, according to Huaxin Securities, on May 27, Changxin Technology's IPO on the Sci-Tech Innovation Board was successfully approved, aiming to raise 29.5 billion yuan for upgrading its memory wafer manufacturing production line, DRAM technology upgrades, and forward-looking research and development. As the largest DRAM manufacturer in China and the fourth largest globally, Changxin Technology's IPO marks the acceleration of domestic storage replacement. Huawei released the Tao (τ) Law at the 2026 International Circuit and System Symposium, which focuses on replacing traditional geometric scaling with time scaling, systematically reducing the time constant τ through innovative technologies such as logical folding, achieving multi-layer collaborative optimization from devices, circuits, chips to systems. This marks a path for domestic chips to innovate and "overtake on a curve" under the constraints of advanced processes. Additionally, according to Guoyuan Securities, BYD launched China's first automotive-grade 4nm chip for autonomous driving, named "Xuanji A3," while ByteDance is developing its own CPU to reduce dependence on chip manufacturers like Intel and AMD. Overseas, Intel is making large-scale advanced packaging investments in EMIB, amounting to several trillion Korean won, with full production expected by 2027; Samsung Electronics will invest $1.5 billion in Vietnam to build a semiconductor testing factory, which will help alleviate the shortage of memory chips. Guojin Securities noted that the competitive advantage of domestically controlled supply chains is increasing, and the semiconductor equipment market has broad prospects. From the perspective of industrial development logic, the explosive demand for global AI computing power resonates with China's semiconductor self-control, jointly opening up the medium to long-term growth space for China's technology industry The global competitive advantage of the self-controllable upstream industrial chain, represented by semiconductor equipment, core materials, and key components, will continue to improve. On one hand, the demand for AI computing power continues to grow rapidly, driving the expansion of demand across the entire chain of chip design, wafer manufacturing, packaging testing, and equipment materials, providing continuous performance growth support for leading domestic companies with technical strength and capacity assurance; on the other hand, the new five-year plan guides resources to concentrate on key core technologies, promoting domestic substitution from mature processes to advanced processes, and from complete equipment to core components and high-end materials, continuously enhancing the level of self-control in the industrial chain. According to data from the China Securities Index official website, the semiconductor equipment ETF managed by CMBI (561980) tracks the China Securities Semiconductor Index, with 80% of its portfolio allocated to equipment and materials, and 20% allocated to CPU/GPU and advanced manufacturing: the "Changxin Storage" concept accounts for as much as 53%, with Northern Huachuang and Zhongwei Company together accounting for 27%, Cambricon and Haiguang Information together accounting for 15%, and SMIC accounting for 6%. The top ten concentration reaches as high as 77%, which is expected to benefit simultaneously from Tao's Law, the expansion of the two storage facilities, and the domestic substitution process. ### Related Stocks - [300666.CN](https://longbridge.com/en/quote/300666.CN.md) - [688256.CN](https://longbridge.com/en/quote/688256.CN.md) - [003026.CN](https://longbridge.com/en/quote/003026.CN.md) - [301095.CN](https://longbridge.com/en/quote/301095.CN.md) - [561980.CN](https://longbridge.com/en/quote/561980.CN.md) - [002409.CN](https://longbridge.com/en/quote/002409.CN.md) - [688146.CN](https://longbridge.com/en/quote/688146.CN.md) - [688981.CN](https://longbridge.com/en/quote/688981.CN.md) - [00981.HK](https://longbridge.com/en/quote/00981.HK.md) - [688072.CN](https://longbridge.com/en/quote/688072.CN.md) - [688041.CN](https://longbridge.com/en/quote/688041.CN.md) - [688361.CN](https://longbridge.com/en/quote/688361.CN.md) - [000852.CN](https://longbridge.com/en/quote/000852.CN.md) - [688416.CN](https://longbridge.com/en/quote/688416.CN.md) - [301283.CN](https://longbridge.com/en/quote/301283.CN.md) - [301633.CN](https://longbridge.com/en/quote/301633.CN.md) - [600520.CN](https://longbridge.com/en/quote/600520.CN.md) - [688302.CN](https://longbridge.com/en/quote/688302.CN.md) - [688720.CN](https://longbridge.com/en/quote/688720.CN.md) - [601881.CN](https://longbridge.com/en/quote/601881.CN.md) - [06881.HK](https://longbridge.com/en/quote/06881.HK.md) - [600621.CN](https://longbridge.com/en/quote/600621.CN.md) - [002594.CN](https://longbridge.com/en/quote/002594.CN.md) - [01211.HK](https://longbridge.com/en/quote/01211.HK.md) - [INTC.US](https://longbridge.com/en/quote/INTC.US.md) - [AMD.US](https://longbridge.com/en/quote/AMD.US.md) - [SSNGY.US](https://longbridge.com/en/quote/SSNGY.US.md) - [600109.CN](https://longbridge.com/en/quote/600109.CN.md) - [002371.CN](https://longbridge.com/en/quote/002371.CN.md) - [688012.CN](https://longbridge.com/en/quote/688012.CN.md) - [HSMD.SG](https://longbridge.com/en/quote/HSMD.SG.md) - [HYDD.SG](https://longbridge.com/en/quote/HYDD.SG.md) - [BYDDY.US](https://longbridge.com/en/quote/BYDDY.US.md) - [BYDDF.US](https://longbridge.com/en/quote/BYDDF.US.md) - [81211.HK](https://longbridge.com/en/quote/81211.HK.md) - [SMSN.UK](https://longbridge.com/en/quote/SMSN.UK.md) ## Related News & Research - [Cambricon Technologies: H1 2026 revenue and profit more than doubled on strong AI chip demand and industry expansion](https://longbridge.com/en/news/295262367.md) - [Cambricon posts 108% surge in revenue amid China’s massive AI chip drive](https://longbridge.com/en/news/295288526.md) - [Cocoa Prices Fall on Rising Nigerian Cocoa Exports](https://longbridge.com/en/news/296637826.md) - [Chinese AI chipmaker Cambricon aims for US$14b revenue over 3 years](https://longbridge.com/en/news/294165889.md) - [Roularta Media Group posts H1 2026 results press release](https://longbridge.com/en/news/296573558.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
