Recently, A-shares have demonstrated an exciting structural market trend. Although the Shanghai Composite Index slightly declined and hovered around 4100 points, the daily trading volume of over 3 trillion yuan indicates that market liquidity remains high. Many individual stocks are drifting into the green, yet there has been no collective sell-off—instead, sector rotation is particularly evident.

The semiconductor industry chain has become the biggest highlight. Stocks like Tianyue Advanced, Tongfu Microelectronics, and others hit the daily limit-up. The logic is quite straightforward: on the policy level, domestic substitution is being intensified; demand for AI chips is driving wafer factories to expand rapidly; coupled with recent technological breakthroughs, these three factors have combined to naturally strengthen the semiconductor concept. Robotics and power grid equipment stocks are also rising in tandem, with Wuzhou Xin Chun, Siyuan Electric, and others hitting the daily limit-up, supported by Tesla's mass production expectations for robots and the 4 trillion yuan power grid investment plan.

An interesting contrast is that the AI application sector is collectively adjusting, with some companies clarifying their business models and bursting the concept bubble; companies like Leverage Media even hit the limit-down. This indicates that funds are undergoing a decisive shift—moving from speculative concept trading to seeking performance certainty. This adjustment is actually healthy, as capital is migrating toward more hardcore sectors.
