 What Is a Stock Exchange?

A stock exchange is a marketplace where investors buy and sell shares of publicly listed companies. It provides a regulated and organized platform that ensures fair trading, transparency, and investor protection.

When a company wants to raise money for expansion, it can offer shares to the public through an Initial Public Offering (IPO). After that, its shares are traded on a stock exchange.

🌍 Major Stock Exchanges in the World

Here are some of the most important stock exchanges globally:

New York Stock Exchange (NYSE) – The largest stock exchange in the world, located in the United States.

NASDAQ – Known for technology companies like Apple and Microsoft.

London Stock Exchange (LSE) – One of Europe’s oldest exchanges.

Pakistan Stock Exchange (PSX) – The main stock exchange of Pakistan.

🏢 How Does a Stock Exchange Work?

Companies list their shares on the exchange.

Investors buy and sell shares through brokers.

Share prices change based on supply and demand.

The exchange ensures rules are followed and transactions are secure.

For example, if many investors want to buy a company’s shares, the price goes up. If many want to sell, the price goes down.
