The stock market entered a correction mode immediately after opening this afternoon. The Shanghai Composite Index finally closed down 0.31%, while the ChiNext Index defied the trend and closed up 0.82%. However, the most eye-catching data was the trading volume — the Shanghai, Shenzhen, and Beijing markets hit a new historical high, reaching 3.99 trillion yuan.

Looking at the sub-sectors, technology growth and resource cycles continued to lead the market rhythm.

In the technology sector, the CSI Software Index rose 3.37%, and the CSI Media Index increased 2.52%; artificial intelligence gained 2.87%, and sci-tech innovation chips rose 2.59%. Satellite communications, after experiencing a series of sharp increases (20251124-20260114) and facing considerable skepticism, still managed to close up 0.92%, demonstrating strong resilience.

The resource cycle sector was also not to be outdone, with oil and gas resources rising 1.67%, and non-ferrous metals up 0.55%, showing a quite strong overall performance.

Other sectors performed variably. The pharmaceutical and medical sector showed some differentiation but signs of bottoming out were evident — medical devices rose 0.96%, and vaccines and biotech declined 0.51%. As for consumer and real estate, they continued their previous weak patterns.
