The concept of stock market was originally a general term for a class of stocks with the same characteristics. For example, the Olympic concept refers to a group of companies that have business opportunities to host the Olympic Games. There are many such concepts, such as network concept, 3G concept, WTO concept, biomedicine concept, overall listing concept and stock index futures concept. But in the stock market, the inherent meaning of this concept is not only a generalization of a certain stock category, but its extended meaning is a kind of market knowledge.
For example, the concept of network, before the network became a concept, the stocks involved in the Internet could only be called plates at best, which was a neutral definition, but the meaning of becoming a concept changed. This concept is a relatively positive investment knowledge. Investors will make very detailed analysis and research on the industry background, investment opportunities and future prospects of concept stocks, and they are not always confident to report them.
