Sectors like communication equipment, semiconductors, fiberglass, and aerospace equipment were among the top performers. In contrast, agriculture, military equipment, environmental protection, and education training stocks faced declines.
Communication Sector Boosted by Policy and Innovation
The communication equipment sector extended its gains from the previous session, with the segment index soaring over 7% in early trading to reach a new historic high. Since the beginning of the year, the index has climbed more than 82%.
Changfei Fiber (601869) stood out with a dramatic 3-minute vertical limit up—its third limit-up in four sessions—setting a new record high. Other notable performers included Tianfu Communication, Dekeli, and Tefa Information, which also hit their limit-up or gained over 10%.
Related segments such as optical communication, 6G, satellite navigation, and telecom services followed suit. Companies like Sunwave Communication, Bocom Integrated, Qiming Information, and StarNet Yuada collectively surged to their daily limits.
Policy Support for Satellite Communications
The Ministry of Industry and Information Technology recently issued guidelines to optimize market access and promote the development of satellite communication industries. By 2030, the policy aims to refine regulatory frameworks, encourage innovations like direct smartphone-satellite connectivity, and expand the user base to over 10 million.
Breakthroughs in 6G Chip Technology
A research team from Peking University and City University of Hong Kong made headlines with a paper published in Nature, unveiling the first adaptive full-frequency high-speed wireless communication chip based on optoelectronic integration. This innovation lays a foundational hardware breakthrough for the practical application of 6G technology.
The IMT-2030 (6G) Promotion Group also held its 24th expert meeting in Beijing, announcing the establishment of a dedicated AI task force. This initiative aims to integrate artificial intelligence with 6G development, fostering collaboration within the industry.
Citic Securities highlighted the strategic importance of satellite communication, noting that licensing processes are expected to accelerate. Industry experts recommend focusing on satellite service providers, manufacturers, and ground equipment suppliers for medium to long-term investment opportunities.
Semiconductor Sector Riding High on Demand
The semiconductor segment rose sharply in early trading, with its index gaining over 2%. Multiple stocks reached their limit-up, including Siteke (20% limit-up), Star Semiconductor, Rockchip, Jianye Shares, and Feilo Acoustics. More than 20 companies in the sector rose by the limit-up or over 10%.
Areas like semiconductors, lithography machines, advanced packaging, and automotive chips also performed strongly. Companies such as Gangyan Nake, Zhangjiang High-tech, Hongbaoli, and Kaimeite Gas hit their limit-up.
AI Driving Chip Demand and Prices
Rapid advancements in AI have led to explosive demand for high-performance chips, particularly those used in AI servers. This has triggered price increases across the industry.
Texas Instruments recently announced its largest-ever price hike, raising rates by 10%–30% on over 60,000 chip models. Industrial and automotive-grade components saw increases exceeding 25%, with some automotive bio-sensing chips doubling in price overnight. Delivery times for industrial PLC modules extended from 16 weeks to 52 weeks.
Strong Production and Trade Data
According to the National Bureau of Statistics, China’s integrated circuit output reached 239.5 billion units in the first half of 2025, an 8.7% year-on-year increase. Customs data showed that imports and exports of integrated circuits also grew steadily, with imports rising 8.9% to 281.9 billion units and exports jumping 20.6% to 167.8 billion units.
Corporate Earnings Reflect Industry Strength
High industry sentiment is translating into robust earnings. Among the 58 semiconductor companies listed on the STAR Market that disclosed half-year results, 40 reported profit growth—17 of them more than doubled their net profit.
Cambricon Technologies turned a profit for the first time in a half-year period, while Zhenratech saw its net profit increase more than tenfold.
Stock performances have been equally impressive. Cambricon’s share price hit a record high, surpassing Kweichow Motaigroup as the highest-priced stock on the A-share market. Since August alone, the stock has surged over 107%. SMIC also rose more than 10% to a historic high.
Tianfeng Securities emphasized that semiconductors, domestic computing power, and supply chain autonomy will remain key long-term trends. Amid ongoing U.S.-China trade uncertainties around AI chips, domestic tech firms are expected to increase procurement of local alternatives, benefiting suppliers across the ecosystem.
Investment Outlook and Strategic Considerations
The stunning rise of Changfei Fiber and its peers underscores the vitality of China’s tech and communication sectors. With continued policy backing, innovation milestones, and growing demand—especially in AI and next-generation communications—these industries are positioned for sustained growth.
Investors should, however, remain mindful of market volatility and regulatory developments. Diversification across sub-sectors—such as satellite communications, semiconductor manufacturing, and AI infrastructure—can help manage risk while capturing growth.
For those looking to capitalize on these trends, monitoring policy announcements, earnings reports, and global tech partnerships is essential. Staying informed through reliable financial news sources and market analysis can provide an edge in navigating this dynamic landscape.
Whether you are a seasoned investor or new to the market, consider consulting with a financial advisor to align these opportunities with your overall investment strategy.
