Mainland China's three major stock indices finished Friday's session firmly in positive territory, with the tech-heavy indexes leading the charge while the Shanghai Composite gave back earlier gains to close nearly flat. The ChiNext Board jumped 3.41% to close at 3,398.68 points, outperforming the broader market significantly. The Shenzhen Component Index advanced 1.91% to 13,774.91, while the Shanghai Composite inched up a mere 0.07% to finish at 3,932.70 points. The STAR 50 Index climbed 2.42% to 1,615.53, and the Beijing Stock Exchange 50 Index added 0.85% to 1,096.85. Total turnover on the Shanghai and Shenzhen exchanges reached 1.946 trillion yuan, representing a contraction of roughly 84.65 billion yuan compared with the prior session. Market breadth tilted positive, with 3,167 stocks advancing versus 2,196 declining, and 95 names hitting their daily upward limit against just two limit-downs, translating to about 57% of all listed stocks rising.
Across sectors, the landscape was sharply divided as computing hardware and artificial-intelligence-related names spearheaded gains, while defensive groups lagged. Leading the upside were CPO (co-packaged optics), PCB, electronic components, electronic chemicals, optical modules, memory chips, and agriculture and aquaculture stocks. On the flip side, precious metals, insurance, coal, brokerages, and kitchen and bathroom appliances suffered the steepest losses. The divergence between the tech-heavy growth indices and the flat Shanghai Composite highlighted a clear rotation in market leadership, driven primarily by a confluence of catalysts in the technology and agriculture spaces.
Key Market Drivers: Hardware Rout and Policy Tailwinds
The most prominent theme of the session was the explosive rally in computing hardware stocks, with the CPO, optical module, PCB, electronic component, electronic chemical, and memory chip segments all posting outsized gains. Zhongji Innolight surged more than 10%, posting the highest turnover on both exchanges and reclaiming a market capitalization of 1 trillion yuan. The stock received a fresh catalyst when Goldman Sachs initiated coverage on its H-shares with a "Buy" rating and a 12-month price target of HK$3,267. That bullish call, combined with OpenAI's unveiling of GPT-6 Astra over the weekend which reignited AI investment enthusiasm, and last Friday's robust performance of US optical communications stocks with the Philadelphia Semiconductor Index rising over 3%, fueled a broad-based rally across the hardware complex.
In the agricultural sector, momentum continued as Yasheng Group notched its third consecutive daily limit-up, while Dunhuang Seed and Jinjian Rice also hit their upper price limits. The buying interest followed the joint release on September 7 by six ministries, including the Ministry of Agriculture and Rural Affairs, of an implementation plan to prioritize agricultural and rural development and improve the investment mechanism for rural revitalization. The plan sets a target of basically establishing a structurally sound, scientifically managed, and quality-and-efficiency-oriented rural revitalization investment system by 2030.
Consumer-related stocks also saw renewed buying, with retail and tourism names leading the advance. Zhongbai Holdings, Central Plaza, Baida Group, Guilin Tourism, and Huatie Hotel all locked in their daily limit-ups. The strength followed a directive issued on August 31 by seven government departments, including the Ministry of Commerce, which outlined implementation opinions aimed at expanding and upgrading commodity consumption, with a goal of reaching approximately 60 trillion yuan in total retail sales of consumer goods by 2030. Meanwhile, the media and publishing sector extended its winning streak, with Longban Media securing a sixth consecutive limit-up and China Publishing posting its second straight limit-up.
Sector Roundup: Surging Momentum and Shifting Leadership
Within the red-hot CPO and optical module space, the rally was broad-based. Zhongji Innolight climbed over 10% with the highest trading volume in the market, while Eoptolink advanced 8.08%, Tianfu Communication gained 7.36%, and Yuanjie Technology skyrocketed 16.10%. Xunjiexing saw its shares hit the 20% limit-up. The collective surge was underpinned by the Goldman Sachs initiation, OpenAI's latest AI model reveal, and the upbeat overseas optical communications session. In agriculture, beyond the three limit-up names, the entire segment displayed resilience, supported by the fresh government policy blueprint for rural investment. Consumer and tourism plays maintained their upward trajectory, with a flurry of companies locking in daily gains in the retail and travel segments as the consumption expansion measures took center stage.
Turning to the laggards, precious metals, insurance, coal, securities, and kitchen and bathroom appliance stocks were the primary decliners. The precious metals complex opened lower and continued sliding throughout the session, with Hunan Silver falling 4.63%, Zhaojin Gold dropping 3.92%, and Shandong Gold losing 3.83%. In the broader weak group, Xiangcai Securities slipped 5.31%, while China Coal Energy retreated 4.28%. These sectors had accumulated substantial gains in the preceding sessions, making them ripe for profit-taking in Friday's rotation, as investors redirected capital toward the high-octane computing and AI themes.
Market participants continued to digest the implications of both the domestic policy signals and the global AI investment cycle. While the Shanghai Composite struggled for traction, the robust performance in hardware and the steady gains in agriculture and consumption pointed to a market that remains in search of fresh leadership. The substantial gains in the ChiNext Board and STAR 50 Index underscored the sustained appetite for growth and technology exposure, even as turnover shrank from the previous day. The contrasting performance between the tech-heavy indices and the flat Shanghai benchmark suggests that investors are selectively positioning for the next phase of the AI-driven industrial upgrade, while also paying close attention to policy-directed sectors such as rural revitalization and consumption expansion.
