Overview of the plate
On the upward side, sectors such as humanoid robots, end-side AI, and AI comics led the way, while PCBs, consumer electronics, automation equipment, speed reducers, and semiconductors followed the strengthening; on the downside, the coal mining and processing, shipbuilding, insurance, banking, and automotive sectors registered the highest declines. Overall, the trend of small and medium capitalization stocks is strong. The yellow and white line is clearly divided. Capital flows are concentrated in the direction of technological growth such as humanoid robots and end-side AI, and hot spots are rotating rapidly; weighted sectors such as coal and banking have pulled back, with agricultural banks reaching an intraday high of 7.54 yuan, approaching the high of 7.57 yuan on January 13, and the market is showing a pattern of structural differentiation.
