With so many abbreviations running around the finance world, it’s only natural to be a bit confused.

These terms are often used in the news to give you a sense about the state of the economy. If the DOW is up, it’s a good thing and if it’s down, it’s not so good. But what’s the difference between these terms?

You can basically break them down into two categories: stock exchanges and stock indices. Stock exchanges are where different stocks are bought and sold – similar to a grocery store for household goods. Stock indices, on the other hand, measure a specific segment of the stock market by tracking the stocks of a particular group of companies – you could create indices that track car, agricultural, or computer companies.

NASDAQ is a stock exchange where over 5,000 different stocks are traded, while the DOW and the S&P 500 are stock indices. The DOW focuses on 30 of the largest American companies and the S&P focuses on 500 of the strongest American companies.
