AI Hardware and Innovative Drugs Drive a Dual Engine, Extending Sector Divergence
Keywords: ChiNext Index, STAR 50 Index, compute chips, CPO, PCB, innovative drugs, zirconium materials, sector-driven market
Introduction
This morning, the A-share market continued to show clear sector divergence. The three major indices moved unevenly, with the ChiNext Index and STAR 50 Index especially strong, rising 1.39% and more than 3%, respectively. At the same time, the Shanghai Composite edged lower. The market has not formed a broad-based rally; instead, it continues to rotate around a few high-growth sectors. Half-day turnover reached RMB 2.14 trillion, up sharply from the previous session, showing active capital participation. Yet more than 3,400 stocks fell, indicating that risk appetite is concentrating in core themes. Overall, AI hardware, innovative drugs, and upstream materials led the tape, while utilities, insurance, and other traditional heavyweight sectors came under pressure, reflecting the classic pattern of “the strong get stronger, the weak stay under pressure.”
1. Tech Leadership Strengthens as the Compute Chain Turns Broadly Active
On the tape, compute-related themes remain the main target of capital. The CPO concept repeatedly strengthened intraday; Accelink Technologies hit a new all-time high after a four-day, two-board surge, underscoring continued market attention to high-speed interconnect technology. Compute chip names also rose quickly, with Cambricon jumping more than 10% to a record high, further cementing the strength of AI hardware. The PCB sector stayed firm as well: Shiming Technology posted back-to-back 20cm limit-up moves, while Zhongjing Electronics, Hengtong Co., and Xianfeng Holdings all hit limit-up, showing a full-chain rally from chips to optical modules and then to circuit boards.
The essence of this round lies in the continued expansion of AI model training and inference demand, which is pushing data centers toward higher power consumption, higher density, and larger-scale clusters. Compute demand is lifting not only the value of chips and optical interconnects, but also the outlook for PCB, cooling, and servers. Research from TrendForce suggests that the CPO/NPO market could expand rapidly over the next few years, meaning interconnect technology is moving from a supporting role to a strategic asset. In this backdrop, leading companies with technical barriers and supply-chain advantages are more likely to attract sustained capital inflows.
2. Innovative Drugs Recover as Industry Catalysts and Valuation Repair Align
Running alongside the tech theme is the volatile rebound in innovative drugs. Nordi-Land rose more than 15%, while Huasen Pharmaceutical, Haixin Group, Zhaoyan New Drug, and Betta Pharmaceuticals all hit limit-up or surged sharply. This shows that funds inside the healthcare sector are beginning to concentrate on innovative drug sub-segments. On the news front, Hong Kong-listed Sino Biopharmaceutical announced a share buyback and said the company’s value is being severely undervalued. Earlier, WuXi AppTec, Akeso, and Hengrui Medicine also disclosed buyback or share-accumulation plans, which helped lift confidence.
More importantly, the market’s expectations for BD overseas deals continue to rise. Data show that by early June, both upfront payments and total deal value in innovative drug overseas transactions had already reached high levels, indicating that Chinese innovative drug developers are gaining stronger bargaining power in global partnerships. For capital markets, the recovery in innovative drugs is not driven purely by sentiment; it is based on internationalization capabilities, pipeline progress, and commercialization expectations. As policy support and overseas expansion logic continue to strengthen, companies with core pipelines and strong R&D capabilities are likely to remain a medium- to long-term focus for funds.
3. Upstream Materials and Policy Expectations Rebound Together, Zero-Carbon and Resources Draw Attention
Today, the nonferrous metals and zirconium theme also stood out. Aidite, Orient Zirconic, and Sanxiang Advanced Materials all hit limit-up, while Sinocera and Shenghe Resources followed higher. On the news side, Aidite disclosed that it had received a notice from Japan’s Tosoh about a suspension in zirconia powder supply, but the company had already arranged alternatives and completed customer validation for all new products. This shows that, against the backdrop of accelerated domestic substitution for critical materials, supply-chain security has become an important variable in industrial competition. Capital’s enthusiasm for resources and material localization is, at its core, a renewed affirmation of the self-reliance and controllability narrative.
At the same time, the National Development and Reform Commission proposed speeding up the goal of having newly added clean-energy generation cover all incremental power demand across society, and pushing ahead with zero-carbon parks and zero-carbon transport corridors. This language not only reinforces the policy direction of green and low-carbon transition, but also provides medium- to long-term support for new energy, energy storage, and energy-saving and carbon-reduction sectors. Although the tape has not yet broadened out fully, the policy emphasis on green transition and optimization of incremental electricity structure suggests that new thematic rotations may still emerge later.
4. Risk Appetite Diverges as Heavyweight Sectors Weigh on the Index
In contrast to the strength in high-growth sectors, utilities and insurance weakened notably. Shennan Electric A, Xichang Electric Power, and Yuedian Power A all fell sharply, while China Pacific Insurance, New China Life Insurance, and Ping An dragged lower throughout the session. These sectors usually carry heavier index weight and defensive characteristics, but in the current environment of active turnover and fast theme rotation, capital is more inclined to chase more elastic growth names, leaving traditional heavyweights under pressure.
This also means the core contradiction in the market is not a lack of overall capital, but a shift in capital’s pricing preference: on one side, growth sectors benefit from highly certain industry trends; on the other, low-volatility and low-beta sectors temporarily lose appeal. For investors, understanding this style shift is crucial. One should not judge overall opportunity purely by index moves, but should pay more attention to the rotation rhythm and divergence repair within the main themes.
Conclusion
Overall, today’s market continued the classic pattern of a sector-driven move: AI hardware, innovative drugs, zirconium materials, and other themes rotated higher in turn, pushing the ChiNext Index and STAR 50 Index up; meanwhile, the retreat in utilities and insurance left the Shanghai Composite relatively weak. The rise in turnover shows that participation is still increasing, but widening stock divergence also suggests that short-term trading has become more difficult. Over the coming period, the market will likely continue to rotate around four main themes: AI compute, domestic substitution, innovative drug overseas expansion, and green low-carbon policy. For investors, the key is not to chase short-term sentiment, but to focus on core names with clear industry trends, strong earnings realization, and valuations aligned with growth potential. That will be the key to navigating a volatile market.
