Market Overview: Index Divergence, Shrinking Volume

As of the midday close, China's A-share three major indices collectively adjusted, showing a pattern of stronger Shanghai and weaker Shenzhen. The Shanghai Composite Index edged down 0.17% to 4139.53 points, the Shenzhen Component Index fell 0.68%, and the ChiNext Index saw a larger decline of 1.46%. The combined turnover of the Shanghai, Shenzhen, and Beijing markets was 1.5966 trillion yuan at midday, a decrease of 53.2 billion yuan from the previous trading day. In Hong Kong, the Hang Seng Index rose 0.75%, and the Hang Seng Tech Index gained 1.07%, with tech stocks rebounding to support the market.

Hot Sectors: Cyclicals and Tech Applications Soar Together

Market hotspots showed structural differentiation:

  • Minor Metals Sector Surge: Stimulated by price hike expectations, rare metal stocks rose strongly, with shares like China Tungsten and Hightech and Zhangyuan Tungsten hitting new highs.
  • AI Application Concept Rebound: Software, cloud computing, and other sectors were active. Kingsoft Cloud led the gains, driving related ETFs like the ChiNext Software ETF Hua Xia up 2.9%.
  • Broad Correction in Computing Power Hardware: Previously hot hardware sectors like CPO, PCB, and memory chips collectively retreated. A-share CPO concept stock Eoptolink Technology fell 7%, while InnoLight Technology, T&S Communications, and others dropped over 6%. Semiconductor memory concept stocks like GigaDevice (603986.SH) and Montage Technology saw significant declines.

Outlook: Focus on Structural Opportunities and Risks

The current market exhibits clear structural trends, with capital flowing out of some high-valuation computing power hardware sectors and rotating towards cyclical products with price hike logic and relatively reasonably valued AI application segments. The sharp adjustment in the ChiNext Index reflects internal differentiation and capital repositioning within the growth sector. The technical rebound in Hong Kong tech stocks after a continuous deep correction is notable, but short-selling data remains high, indicating lingering cautious sentiment. Investors should monitor whether trading volume can expand effectively and if the market's main trend can become clearer.
