The stock market plays a vital role in a country’s economy, and at the heart of it lies the stock exchange. Whether you are a novice investor or someone who plans to trade professionally, the first step is to understand the stock exchange and how it works.

The two major stock exchanges in India are the Bombay Stock Exchange(BSE) and the National Stock Exchange(NSE). Let’s learn more about them.

What Is a Stock Exchange?

A stock exchange is a regulated market where buyers and sellers trade financial securities such as:

  • Shares(Equities)
  • Bonds
  • Exchange-Traded Funds (ETFs).

It provides a transparent and structured platform for companies to raise capital and for investors to buy and sell shares.

Stock exchanges operate under strict regulation to ensure fair trading practices, investor protection, and efficient financial management.

How Does a Stock Exchange Work?

Here’s a simple analysis:

  1. Company Listing – A company’s shares are listed on a stock exchange through an initial public offering (IPO).
