AI hardware experiences a full-scale breakout, A-shares trading volume exceeds 2.5 trillion again | Kaiyun Jian Shan

On February 26, the three major A-share indices closed with mixed gains and losses, showing a high-level fluctuation and sector rotation pattern. By the close, the Shanghai Composite Index was at 4,146.63 points, down 0.01%; the Shenzhen Component Index was at 14,503.79 points, up 0.19%; the ChiNext Index was at 3,344.98 points, down 0.29%; and the Beijing Stock Exchange 50 Index fell 0.15%. The combined trading volume of the Shanghai, Shenzhen, and Beijing markets reached 2.5566 trillion yuan, an increase of 75.7 billion yuan compared to the previous trading day, indicating continued active trading. Over 2,400 stocks in the market rose, with clear sector differentiation, and funds concentrated in high-growth sectors with strong market prospects.

The market displayed a clear “technology strong, consumer weak” characteristic. Boosted by Nvidia’s better-than-expected earnings report overnight, the AI hardware industry chain exploded across the board, becoming the market’s strongest theme. Segments such as CPO, high-speed copper cable connections, optical fiber cables, PCBs, and liquid-cooled servers all saw rapid gains, with stocks like Tianfu Communication, Hengtong Optoelectronics, Shenling Environment, and Huafeng Technology hitting new historical highs during trading. The demand for computing infrastructure continued to release, driving large inflows of capital into communication and electronic component sectors, with a strong profit-making effect.

Domestic computing power and semiconductor sectors also strengthened simultaneously. Cambrian’s stock price surged nearly 10% in the afternoon, with domestic computing chips performing well under the dual drivers of the AI wave and independent controllability. Additionally, themes such as wind power equipment, aircraft engines, cultivated diamonds, and sugar substitutes became active in turn. The commercial aerospace sector saw a rally in the afternoon, with companies like Electric Power Blue Sky and Aerospace Power leading gains. Power grid equipment and environmental protection sectors also experienced phased rises, with multiple market hotspots emerging.

In contrast to the technology sector, large-weight sectors such as consumer, real estate, and finance experienced collective adjustments. Insurance, liquor, retail, duty-free shops, automobile manufacturing, and precious metals sectors led declines, as funds withdrew from defensive sectors and previously popular consumer tracks, shifting toward high-growth sectors with strong prospects. The Sci-Tech Innovation Board 50 Index rose 0.85 against the trend, reflecting ongoing investor preference for hard technology and high-growth sectors. Focusing on core tracks and light indices has become a key strategy during this phase.
