What is a Stock Market?
If you are new to investing, the term "stock market" can sound intimidating. But at its core, a stock market is simply a marketplace where people buy and sell ownership in companies – those ownership units are called stocks or shares.
📌 Quick definition: A stock market is a regulated platform (physical or electronic) where investors can trade shares of publicly listed companies. In Pakistan, this is the Pakistan Stock Exchange (PSX).
Why do companies sell stocks?
Imagine a local business in Karachi wants to expand – open new branches, buy machinery, or hire more people. They need money (capital). Instead of taking a bank loan, they can sell a part of the company to the public through an Initial Public Offering (IPO). People who buy those shares become shareholders – partial owners of the company. The company gets the funds, and investors hope the company grows so their shares become more valuable.
How does the stock market work?
The stock market works through an exchange (like PSXThe Pakistan Stock Exchange, the national stock exchange of Pakistan. People buy and sell the shares of listed companies there.

- A company lists its shares on the exchange (IPOInitial public offering. It is the first time that a company sells its shares to the public. After that, the shares can be bought and sold on the stock exchange.Full list of terms →).
- Investors open a brokerage account (or use a virtual simulator like PSE).
- Investors place orders to buy or sell shares at a specific price.
- The exchange matches buyers and sellers – trades are executed.
- After the trade, ownership is transferred electronically (settlement).
📊 PSX example: On the Pakistan Stock Exchange, most shares trade in market lots (e.g., 500 shares for stocks below Rs. 50). You can place a limit order to buy at a specific price or a market order to buy immediately at the best available price.
