The term “goes public” is generally used to address the IPO of an existing company which decides to list its shares on a Stock Exchange.
The company can list its shares with the National Stock Exchange (NSE), Bombay Stock Exchange (BSE) & or any other regional stock exchanges by complying with the listing requirements of such Exchanges as regulated by the Securities and Exchange Board of India (SEBI), which is the regulator for the securities market in India.
Further to an IPO, the company’s shares are traded in an open market. Those shares can be further sold by investors through secondary market trading.
