What is a stock exchange, and what is the difference between the NYSE and Nasdaq?
An exchange is the venue where buy and sell orders meet. The NYSE and Nasdaq are the two big US ones; they differ in history and style more than in anything that affects you as an investor.
A stock exchange is the organised marketplace where shares change hands. It sets the rules, lists the companies, matches orders and publishes the prices. In the US the two big ones are the New York Stock Exchange and the Nasdaq, and between them they handle most of the country’s trading.
The NYSE is the older one, dating from 1792, with the famous trading floor. It historically listed established, industrial-era companies. Nasdaq launched in 1971 as the first fully electronic exchange and became the home of technology companies, which is why Apple, Microsoft and Nvidia trade there.
For you as an investor, the difference is close to nil. Your broker can buy a share on either. Fees, speed and protections are essentially the same. The listing exchange is mostly a bit of trivia on the company’s quote page.
Worth knowing: a lot of trading no longer happens on the exchanges at all, but in private venues and via market makers who execute your order internally. That is legal and usually fine for retail-sized trades, and it is part of why your broker can charge no commission.
