The share market, also called the stock market, is a place where people buy and sell shares of companies. The main purpose is to help companies raise money for growth and allow investors to earn profits by buying shares. In India, the major share markets are the Bombay Stock Exchange (BSE), established in 1875, and the National Stock Exchange (NSE), established in 1992. Both are controlled by the Securities and Exchange Board of India (SEBI), headquartered in Mumbai.
Around 5,000 companies are listed on the BSE and 2,000 on the NSE. You can buy shares through a bank's trading account or using online platforms like Zerodha, which allow easy online investments.
