Summary: ①Yesterday's market presented a polarization trend, and the semiconductor industry chain set off a wave of limit up, while some blue chip weights showed obvious declines; ②The semiconductor sector has emerged as a concentrated sector with expanded height and capacity, and there may be phased opportunities; ③In the short term, after yesterday's single-day outbreak, the semiconductor sector may encounter cashing selling pressure today, so pay attention to the strength of the backflow after the divergence.

Yesterday's market continued the trend of differentiation, with the entire semiconductor industry chain exploding, storage chips, lithography machines, advanced packaging and other directions rising, and driving the market's short-term sentiment warming up. On the other hand, the downdraft of some weighted stocks has put obvious pressure on the index (especially the Shanghai Composite Index). Although the index has not yet clearly stopped falling and stabilized, under the background of panic being cleared collectively last week, market's selling momentum may tend to weaken. If the subsequent sentiment can continue to warm up, it will also be expected to drive the index's turnaround.

The core reason for the market's polarization is still that there is no incremental capital inflow in the short term (and the volume is even continuing to shrink). When a large number of stock funds are unwilling to chase dividends again, and also see the lack of short-term logic for Maoning, they try to switch to a new direction, so the technology sector represented by semiconductors is valued by funds.

Looking at yesterday's market performance, the semiconductor sector has emerged as a concentrated sector, with Xiehe Electronics breaking through the 5-board, becoming the speculative leader of short-term sentiment, and Belling Corp., Ltd., Lingyi and Taichi Semiconductors also completed the limit up, collectively opening up the sector's height. In addition, the money-making effect of individual stocks yesterday further extended to the subsequent individual stocks, with nearly 20 stocks in the sector hitting the limit up, and more and more individual stocks transferring to long positions in the medium term trend. Therefore, under the background of effective activation of sector height and capacity, there may be phased opportunities in this sector. In the future, still pay attention to large-cap targets with relatively positive logic, or trend opportunities for segmented leaders, as well as arbitrage opportunities based on early-core targets with stock elasticity.

But it should be noted that in the recent market, after a hot spot collectively explodes in a single day, it often triggers collective cashing by some funds. In addition, if other hot spots have strong money-making effects today and lead to diversion, the semiconductor sector is likely to encounter a lack of follow-up and face differentiation today. At that time, it will be the best point to judge the strength of this round of semiconductor trend. If the strong backflow can be completed quickly after the divergence, the leading position of the semiconductor main line may be further consolidated. In addition, with the strength of the semiconductor sector, it is expected to drive the overall technology growth sector to rebound, and early hot topics such as consumer electronics, commercial aerospace, AI, and low-altitude economy may also usher in opportunities for repeated activities.
