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.
