What is the Stock Market? Beginner’s Guide to Stocks, Shares & Equity.
A Beginner’s Introduction
The stock market is like a marketplace where people trade small pieces of companies, called shares, to become part-owners and earn money. These ownership units are called stocks, shares, or equity – terms that are often used interchangeably but have slight differences.
If you’re new to finance or investing, don’t worry – this article will help you understand the basics of the stock market, the key terms, and how it all works in simple language.
What is the Stock Market?
The stock market is a platform where stocks of companies are traded. It’s like a market where you can buy and sell small pieces of businesses, just like trading goods.
In India, the two main stock exchanges are:
- BSE (Bombay Stock Exchange)
- NSE (National Stock Exchange)
Each company listed on these exchanges offers shares to the public. When you buy a share means you own a small part of the company.

How Does the Stock Market Work?
Here’s a step-by-step explanation:
- Companies raise money by offering shares to the public (called IPO – Initial Public Offering).
- Investors buy these shares through stock exchanges like BSE or NSE.
- Share prices go up and down based on:
- Company performance
- Market demand and supply
- Global news and economic conditions
- Investors can buy low and sell high to make a profit.
You can invest in stocks using a Demat account and trading account, usually through platforms like Zerodha, Groww, or Upstox.
Stock vs Share vs Equity – What’s the Difference?
Though often used interchangeably, here are the key differences:
Term | Meaning |
---|---|
Stock | A general term for ownership in one or more companies. |
Share | A unit of stock representing ownership in a specific company. |
Equity | The total ownership value a person has in a company (or companies). |
Example:
If you own 100 shares of Infosys, you have a shareholding (ownership) in Infosys. That ownership is also your equity in the company. All together, you own stocks in Infosys.

Why Do People Invest in the Stock Market?
Here are the top reasons:
- Wealth Creation – Long-term investment in stocks has the potential for high returns.
