Today’s trading hotspots are quite interesting. Nine stocks with billion-level transactions appeared, among which Sanhua Intelligent Controls ranked first with a trading volume of 22.473 billion yuan, rising 5.35% to hit a new high; China Aerospace Development was second with 17.932 billion yuan, hitting the daily limit and reversing the previous plunge; Zhongji Xuchuang was third with 13.944 billion yuan, but fell 3.48%.

The most noteworthy aspect is the differentiation of sector hotspots. Among the top ten stocks by trading volume, four are from the commercial aerospace concept—Aerospace Development, China Satellite, Aerospace Electronics, and Xinwei Communications—and three are related to AI. Clearly, funds are switching back and forth between these two directions. The commercial aerospace sector is especially strong, with Aerospace Development, China Electronics, and China Satellite all hitting the daily limit, and Xinwei Communications surging 16.98%.

In terms of profitability, core stocks are performing significantly better than the overall market. The entire A-share market saw more declines than gains, but among the top ten stocks by trading volume, the ratio of gainers to losers is 7:3, indicating that large funds are clustering around hot spots. As December approaches its end, this phenomenon of funds grouping around core themes is becoming more evident—mainly in the rising of the commercial aerospace and AI technology sectors, while other sectors remain relatively calm.

Specifically, non-ferrous metals also showed some performance. Zijin Mining traded 11.803 billion yuan, rising 3.14%, as a leader in gold and copper. The optical module sector appeared lukewarm; New Easun, despite trading 12.503 billion yuan and ranking sixth, fell 3.39%. Industrial Fulian traded 9.817 billion yuan and ranked tenth, also declining as an AI server concept stock. BlueFocus is somewhat special, with a transaction volume of 11.165 billion yuan; as a Hong Kong-listed AI application concept, it directly hit a 20cm daily limit.

From this transaction structure, it’s clear that market focus is rotating. Who can sustain the inflow of funds—commercial aerospace or AI technology—may be the next key point to watch.
