Hot concepts frequently trigger stock price fluctuations and A-share companies are intensively warning to clarify the boundaries of their business risks.

Since June 17th, more than 50 A-share companies have issued announcements of unusual stock price movements or risk warnings regarding hot concepts such as AI servers, optical modules, humanoid robots, and controllable nuclear fusion, actively responding to market concerns, clarifying business boundaries, and alerting investors to risks. Experts believe that investors must be cautious of the "three noes" signals from related companies, namely the lack of core technology updates, lack of scale orders, and lack of cash flow support, in order to avoid the trap of speculative concepts. In the medium to long term, industry valuations will gradually shift from "narrative-driven" to "performance-verified" logic, and companies that truly possess technological barriers and order conversion capabilities will receive valuation premiums.
