There is a case worth paying attention to. The stock price of a certain company declined consecutively over three trading days, with a total drop of over 20%, triggering an abnormal volatility warning. At first glance, it’s quite alarming, but looking deeper reveals some interesting points.

After self-examination, the company straightforwardly stated: We do not engage in commercial aerospace at all, nor do we have related investments. The actual business is just supporting some rocket engine components as a contract manufacturer. This segment’s revenue accounts for less than 2% of the total, and it is still operating at a loss.

This is a typical scene of concept hype backfiring. The market labels it with the "aerospace concept," and funds rush in to speculate on the theme. However, the company’s core business doesn’t match this concept at all. Once the truth is revealed, investors who took over will have to bear the cost of the decline.

This lesson applies to all investors: whether in A-shares or the crypto market, never be blinded by pure concepts. You need to look at actual business support, data proportions, and profitability. Hype without fundamentals will eventually lead to debt repayment. Next time you see a hot concept or theme, ask yourself three questions: How much does this concept represent? Is there actual income? Is it profitable? Think it through before taking action.
