Stock is the abbreviation of share certificate, which is a kind of valuable securities issued to shareholders by joint-stock enterprises as holding certificates to raise funds and obtain dividends and bonuses. Each share represents the shareholder's ownership of the basic unit of the enterprise. This kind of ownership is a comprehensive right, such as attending shareholders' meetings, voting, participating in major decisions of enterprises, collecting dividends or sharing dividends. Each stock in the same category represents the equal ownership of the enterprise.
Concept stocks refer to stocks with some special connotations, as opposed to blue-chip stocks. Blue-chip stocks need good performance support. Concept stocks rely on a certain theme, such as the concept of asset reorganization and the concept of three links to support prices. This connotation is usually regarded as a theme of stock selection and speculation, and has become a hot spot in the stock market.
Concept stocks are stock market terms, as a way of stock selection. Compared with blue-chip stocks, they must have good business performance support, and concept stocks are only a combination of stocks with the same theme and type. Because of the advertising effect of concept stocks, there is no guarantee of any profit.
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. However, in the stock market, the internal meaning of the 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.
