What Is a Stock Exchange? NYSE, Nasdaq, and Others
When you buy or sell a stock in your brokerage app, the trade is not happening “inside” the app. It is routed to a stock exchange. A stock exchange is a marketplace for buying and selling shares. Understanding what a stock exchange is, and how places like the NYSE and Nasdaq work, helps beginners see where trading actually happens and why it matters.
What Is a Stock Exchange?
A stock exchange is an organized marketplace where stocks and some other securities are traded.
Key ideas:
Buyers and sellers place orders through brokers.
The exchange’s systems match these orders so trades can happen.
The exchange sets rules to keep trading fair and orderly.
You do not trade directly with the company most of the time. You trade with other investors through this marketplace.
NYSE: New York Stock Exchange
The NYSE (New York Stock Exchange) is one of the largest and oldest stock exchanges in the world.
Basic traits:
Located in New York City.
Home to many large, well-known “blue-chip” companies.
Historically famous for its physical trading floor with human traders, even though most trading is now electronic.
Companies must meet certain size, financial, and reporting standards to list their shares on the NYSE.
Nasdaq
Nasdaq is another major U.S. stock exchange, known for many technology and growth companies.
Basic traits:
Fully electronic, with no traditional open-outcry trading floor.
Uses a network of market makers to provide quotes and help keep trades flowing.
Hosts many well-known tech, biotech, and growth-oriented businesses.
Like the NYSE, Nasdaq has listing standards companies must satisfy to be traded there.
Other Stock Exchanges Around the World
There are many exchanges globally, such as:
London Stock Exchange (LSE) in the United Kingdom.
Tokyo Stock Exchange (TSE) in Japan.
Toronto Stock Exchange (TSX) in Canada.
Each has its own listed companies, trading hours, and rules. Many global index funds and ETFs hold stocks from several of these markets at once.
Why Stock Exchanges Matter for Beginners
Stock exchanges are important because they:
Give companies a way to raise money by selling shares to the public.
Provide liquidity, making it easier for investors to buy and sell.
Offer transparent prices and rules, which helps build trust in markets.
For beginners, it is useful to know:
Your trades go through exchanges (or related venues), not directly to the company.
Prices move based on supply, demand, earnings, news, and overall market mood.
Exchanges reduce some types of risk, but they do not protect you from price swings. Any stock can still rise or fall in value.
Takeaway
A stock exchange is a regulated marketplace where buyers and sellers trade shares. The NYSE and Nasdaq are two of the biggest and most watched exchanges, and many others operate worldwide. For beginners, understanding stock exchanges makes the trading process less mysterious and reinforces that, even in organized markets, stock prices can move up or down at any time.
