Stock basics

What to know about the stock market Add to ...

​The stock market brings together people who want to sell stock with those who want to buy stock. When you buy stock (or equity) in a company, you receive a piece of the company and become a part owner.

The stock market is made up of:

Where stocks are traded

1. Stock exchanges

A stock exchange is an organized market in which an investor can trade securities in a publicly visible manner, under rules that apply to all users of that exchange.

If a company is listed on a recognized stock exchange, it must:

  • distribute a certain number of shares,

  • file appropriate information about its management team, and

  • provide specific financial information.

In the past, stockbrokers used to meet to buy and sell stock in a physical location. They would send trade instructions to the trade floor and traders would execute the trades in person.

All stock trades are now done electronically. Each stock exchange in Canada focuses on certain kinds of investments:

  • Toronto Stock Exchange (TSX)​ – serves the senior equity markets and lists well-established companies.

  • TSX Venture Exchange – serves the public venture equity market and lists emerging companies that don't meet the listing criteria of the TSX.

  • Montreal Exchange – focuses on specialized investments such as stock options and derivatives.

2. Other marketplaces

Stocks are also traded through:

  • alternative trading systems (ATSs) – automated trading systems that bring together dealers and institutional investors who trade large quantities of stocks, and

  • over-the-counter (OTC) markets – dealer networks where "unlisted” stocks are traded.

How stock prices are set on a stock exchange

The buyer and seller must agree on a price before a stock can be bought or sold. Here's how it works:

  • People compete to buy the stock if they believe that its price will rise and they will make a profit.

  • Sellers compete to find buyers for their stock at the highest possible price.

  • There are usually several investors trying to buy and sell stock in the same company at the same time. It’s like a big computerized auction.

  • Once a stock is bought or sold, the price is posted so that everyone knows the latest price.
