driving factors
On the same day, the market showed a restorative pattern where technological growth resonated with low consumption: the three major indices opened low and became popular collectively, the GEM index rose 1.49%, and Science and Innovation 50 rose 1.61%, leading the way. The main direction of capital clearly pointed to AI hardware and low-level real estate consumption.

Liquid cooling, advanced packaging, 1.6T optical modules, etc. have entered a stage where order visibility is increasing. The real estate sector has been catalyzed by policy easing.

2. Real estate: The sector continued to rise, and many stocks such as Binjiang Group, CCCC Development, and Rongsheng Development rose and stopped.
