What Is the Stock Market?
The stock market is where shares of public companies are bought and sold. It lets companies raise money to grow and lets investors own a piece of those businesses. Here's how it works, step by step.
What is a stock?
A stock (or share) is a small piece of ownership in a company. If a company has one million shares and you own 1,000, you own 0.1% of it.
As an owner, you benefit when the company grows: the share price can rise, and some companies pay part of their profits as dividends.
What is the stock market?
The stock market is the network of exchanges where buyers and sellers trade shares. Major exchanges include the NYSE and Nasdaq in the US, and the NSE and BSE in India.
The exchange matches buy and sell orders and makes sure trades are settled fairly and transparently.
How does the stock market work?
- 1A company lists its shares on an exchange through an IPO.
- 2Investors open an account with a broker to place orders.
- 3Buy and sell orders reach the exchange, which matches them at agreed prices.
- 4The trade settles: money goes to the seller and shares to the buyer's account.
- 5Prices keep changing as new buy and sell orders arrive.
Key players in the stock market
| Player | Role |
|---|---|
| Companies | Issue shares to raise money for growth |
| Investors | Individuals and institutions who buy shares |
| Stock exchanges | Marketplaces that match buyers and sellers |
| Brokers | Firms that place orders on the exchange for investors |
| Regulators | Bodies such as the SEC (US) and SEBI (India) that protect investors and enforce rules |
Why do stock prices go up and down?
- Company results: growing profits tend to lift prices
- Economic news: interest rates, inflation and growth data
- Investor sentiment: optimism and fear
- Supply and demand: more buyers than sellers pushes prices up
Primary vs secondary market
- Primary market: a company sells new shares directly to investors, for example in an IPO.
- Secondary market: investors trade existing shares with each other on the exchange. This is what most people mean by 'the stock market'.
What are stock market indices?
An index tracks a group of stocks to show how the market is doing. The S&P 500 and Nasdaq-100 are widely followed in the US; the Nifty 50 and Sensex in India.

Frequently asked questions
What is the stock market in simple words?
The stock market is a marketplace where people buy and sell shares of companies. Owning a share means owning a small part of that company.
How does the stock market make money for investors?
Investors can earn in two ways: when the share price rises above what they paid (capital gains), and through dividends that some companies pay from their profits.
Is the stock market risky?
Yes. Share prices can fall as well as rise, and individual companies can fail. Diversifying across many companies and investing for the long term reduces, but does not remove, that risk.
What are stock market trading hours?
Regular trading on the NSE and BSE in India runs from 9:15 am to 3:30 pm IST, Monday to Friday. In the US, the NYSE and Nasdaq trade from 9:30 am to 4:00 pm Eastern Time. Markets close on exchange holidays.
What is the difference between a stock exchange and the stock market?
