The renewed surge of A-share semiconductors should not be bought based on industrial logic alone; caution is needed as this may constitute a crowded trade.
When the A-share semiconductor and AI hardware chains surge rapidly, two extreme reactions tend to emerge: one type of person feels that missing out on gains (FOMO) is more painful than actually incurring losses, while another believes that excessive rises necessarily signal a bubble.
Both of these are too fast. In areas like semiconductors, computing power, optical modules, and storage, the industrial logic might be true. AI training and inference will indeed boost hardware demand, and domestic substitution has certainly provided narrative space and order opportunities for local companies. The problem is that just because the industrial logic holds true does not mean that the probability of investing in it now is good.
Similar market trends have occurred repeatedly in history: the liquor sector (Baijiu), new energy, pharmaceuticals, core asset grouping, and TMT. Each time, there was real logic behind it. When these sectors decline, it doesn’t necessarily mean the logic has disappeared; rather, the timing/rhythm between valuation, positioning, earnings realization, and liquidity was off.
