All publicly traded companies can be bought and sold on one of the many stock exchanges that exist all over the country and the world, but rarely do you hear about any exchanges other than the New York Stock Exchange or NASDAQ. And wait… why do we even need more than one?

Why is there a stock exchange in Cleveland? Well, there isn’t one, but there used to be. Many of the small, regional exchanges that no longer exist were necessary because, without the Internet and computers, it wasn’t possible to buy and sell stocks quickly across vast distances. Today, huge exchanges like the NASDAQ only exist on a computer network – there is no NASDAQ trading floor.

Each different exchange only trades a limited number of companies and can impose rules on the companies it lists, or only allow companies of a certain size or stock price. The NYSE has a minimum share price and share volume so that only big companies can trade, so it’s considered a less risky exchange than say the NASDAQ which doesn’t have those types of restrictions. Exchanges can also only trade specific types of securities. The Chicago Mercantile Exchange (CME) only trades financial and commodity derivatives for example.

Being familiar with the differences between the various exchanges can help you make decisions about investing in companies traded on those exchanges and empower you to have an informed discussion of your investments with your broker or financial advisor.
