AI concept stocks surge across the board: dual drive of computing infrastructure and AI applications
On July 27, 2026, the A-share market saw a comprehensive outbreak of AI concept stocks. By close, the Wind Artificial Intelligence Index surged 4.82%, with over 30 stocks in the sector hitting daily limits or rising over 10%. Sub-sectors including computing infrastructure, AI chips, AI applications, and AI healthcare performed in rotation, with strong market bullish sentiment. In Hong Kong, the AI sector also strengthened, with SenseTime and Baidu both gaining over 5%.
Market review: computing leaders lead rally, application side blooms across multiple fronts
Today's AI concept stock trends clearly showed two main lines: one is computing infrastructure, and the other is AI application implementation.
Computing infrastructure: Sugon and Cambricon hit record highs
On the computing side, Sugon (603019.SH) hit the daily limit early in the session, with its stock price hitting a record high and turnover exceeding 12 billion yuan. Cambricon (688256.SH) rose 12.3%, with its market cap returning to above 200 billion yuan. In addition, GPU concept stocks such as Hygon Information (688041.SH) and Jingjia Micro (300474.SZ) both rose over 7%. Analysts believe that recent approvals of multiple ultra-large data center projects, coupled with accelerated domestic computing substitution, are driving the continuous strength of the computing infrastructure sector.
AI applications: iFLYTEK and TRS lead gains, education and healthcare become hotspots
The AI application side also performed strongly. iFLYTEK (002230.SZ) rose 6.8%, after the company released its new-generation Spark Big Model V5.0 yesterday, achieving breakthroughs in mathematical reasoning and multimodal understanding. TRS (300229.SZ) hit the daily limit, with its big model accelerating implementation in financial risk control scenarios. In the AI healthcare sector, Winning Health (300253.SZ) surged 9.5%, and the AI healthcare product under Baidu (9888.HK) was approved for market, boosting sector sentiment. In AI education, stocks like iFLYTEK and Seewo (002841.SZ) attracted capital inflows.
Capital flows: main force net inflow exceeds 10 billion yuan, northbound capital increases positions in AI leaders
From the capital perspective, today's AI sector saw main force net capital inflows of 14.8 billion yuan, ranking first among all industries. Northbound capital also significantly increased positions, with Shanghai-HK Stock Connect net buying Sugon for 820 million yuan and Shenzhen-HK Stock Connect net buying iFLYTEK for 650 million yuan. Margin trading data shows that the margin balance of AI concept stocks increased by over 3% in the past week, indicating leveraged capital is optimistic about the outlook.
On the ETF side, the China Universal CSI Artificial Intelligence ETF (515070) saw trading volume exceeding 2 billion yuan today, trading at a premium, indicating over-the-counter capital actively entering through ETFs. Many AI-themed fund net values hit new highs since inception.
Policy and industry dynamics: multiple regions introduce new AI industry support policies
Recent favorable policy winds have provided important support for the AI sector's strength. On July 25, the Ministry of Industry and Information Technology and six other departments jointly released the "Three-Year Action Plan for AI-Enabled New Industrialization (2026-2028)", proposing to create 50 national-level benchmark application scenarios for AI-enabled new industrialization by 2028, and provide financial support in basic links such as computing power, algorithms, and data. Beijing today announced the establishment of a hundred-billion-yuan AI industry investment fund, focusing on supporting large model training, computing center construction, and AI chip R&D. Shanghai, Shenzhen, Hangzhou and other places have also successively introduced AI application subsidy policies covering medical, education, manufacturing and other fields.
At the industry level, multiple leading companies recently released important products: Huawei announced that its Pangu Big Model 5.0 surpassed the European Center model in weather forecast accuracy; iFLYTEK's Spark Big Model V5.0 led in multiple benchmark tests; ByteDance's Doubao Big Model reached 100 million daily active users. These messages continue to boost market confidence.
Institutional view: from concept hype to earnings delivery, focus on three main lines in H2
Multiple brokerages have released research reports, believing that the AI sector is shifting from a thematic speculation phase to a fundamentals-driven phase. CITIC Securities believes that with the improvement of large model capabilities and the expansion of application scenarios, the performance of companies in the AI industry chain upstream and downstream is expected to be delivered in the second half of the year. It recommends focusing on three main lines: computing infrastructure, AI application software, and AI hardware (such as robots and smart terminals).
Hua An Securities points out that the current valuation of the AI sector is at a reasonably high level, but considering that the industry penetration rate is still early, there is huge room for future growth. The institution is particularly optimistic about the progress of AI implementation in vertical fields such as education, healthcare, and finance, believing that these fields have data barriers and scenario advantages, and leading companies are expected to achieve profit inflection points first.
China Merchants Securities reminds that short-term differentiation within the sector should be noted. Some concept stocks that follow the hype have inflated valuations, and investors should focus on high-quality targets with genuine technical barriers and order implementation. At the same time, pay attention to the risk of transmission of fluctuations in overseas technology stocks to the A-share AI sector.
Risk warning
Despite the strong performance of AI concept stocks today, investors should still pay attention to the following risks: first, uncertainty in Fed policy may trigger adjustments in global technology stocks; second, the commercialization progress of some AI companies may fall short of expectations; third, intensified industry competition may lead to declining gross margins; fourth, regulatory policies may impose restrictions on AI application scenarios. Investors are advised to view short-term fluctuations rationally and focus on medium- to long-term industry trends.
Investment strategy: focus on sub-sector leaders with strong earnings certainty
Based on the current market environment, we suggest investors focus on the following directions:
- Computing infrastructure: AI computing demand continues to surge. Leaders such as Sugon, Hygon Information, and Inspur Information, which have order and capacity advantages, are worth tracking.
- AI chips: Domestic substitution accelerates, and domestic GPU manufacturers such as Cambricon and Jingjia Micro are expected to continue benefiting.
- AI applications: iFLYTEK leads in education and healthcare implementation; TRS and Kingsoft Office are steadily advancing in large model applications.
- Data elements: Data is the core asset of AI. Pay attention to data operation platforms such as eHualu and Deep Sea.
Investors can invest through individual stock allocation or participating in AI-themed ETFs (such as China Universal AI ETF, Huatai PineBridge STAR AI ETF, etc.) to diversify risks. It is also recommended to regularly monitor company financial reports and use the degree of earnings delivery as the basis for portfolio adjustment.
