The "concept stocks" here are relative to blue-chip stocks, and refer to the combination of the same type of stocks that rely on the same theme and are included in the stock selection object. Concept stocks mainly have a strong advertising effect. The profitability of a stock may be average, and it usually receives little attention. However, once it is included in the portfolio of popular concept stocks, it will easily attract investors' attention and become the focus of the stock market. For example, the concept of HarmonyOS system mentioned above, which uses the related work of participating in HarmonyOS system as a propaganda means, brings heat to a stock.
Investors must understand that concept stocks are topic-based, and the word "so-and-so concept stocks" is only a propaganda means, and the true performance of their stocks is not necessarily good, which does not guarantee profitability.
Secondly, the so-called same type does not necessarily refer to the stock of a certain industry, but mainly depends on what topic or concept it is based on. If it is a network concept stock, it may be mostly a stock in the network industry. What other concepts are there, such as WTO, biomedicine, overall listing, stock index futures and so on. And there are many kinds.
