Listing is a term in the securities market. In a narrow sense, initial public offering (IPO) refers to the process that an enterprise issues shares to investors for the first time through a stock exchange in order to raise funds for enterprise development. When a large number of investors subscribe for new shares, they need to draw lots for allotment, which is also called drawing new shares. Investors who subscribe expect to sell at a price higher than the subscription price. Under the environment of China, the listing is divided into two parts: China company is listed on China Shanghai Stock Exchange and China Shenzhen Stock Exchange; China companies go directly to non-Chinese mainland stock exchanges (such as Hongkong Stock Exchange, new york Stock Exchange, Nasdaq Stock Exchange, London Stock Exchange, etc.). ) and China companies indirectly set up offshore companies overseas and listed on overseas stock exchanges in the name of offshore companies (red chips).
