Generally speaking, it depends on market value. Large-cap stocks usually refer to the stocks of listed companies with a large number of tradable shares.

Large-cap stocks: stocks issued by large companies with a total market value of more than 5 billion yuan. The calculation of total capital is the number of existing shares of the company multiplied by the market value of the shares. Large companies are usually shipbuilding, steel, petrochemical and banking companies. Mid-cap stocks (BOC, ICBC, PetroChina, Sinopec, CSSC, Baosteel, Yunnan Copper, China South Locomotive, etc.). ) is a stock with a circulating amount between large-cap stocks and small-cap stocks.

Small-cap stocks are stocks issued by listed companies with a small amount of tradable shares. At present, in China, no more than 654.38 billion outstanding shares can be regarded as small-cap stocks. Big or small, the main basis for judgment is the listing and circulation of the company.
