Listed companies have different industries, different nature of enterprises, different development, and different final scales.
There are large super-large-cap stocks such as PetroChina and Industrial and Commercial Bank of China, with a total share capital of more than 1000 billion shares and a market value of trillions;
There are also small and medium-sized boards and growth enterprise market, especially the current growth enterprise market. Many companies have only tens of millions of shares, and some have a market value of only 230 million.
Such a contrast, you will understand. Listed companies are large and small, and the large ones are mainly large-scale energy and production controlled by some countries and large companies monopolized by some countries that control the economic lifeline; Small companies are mainly innovative and technical small companies.
