The stock market is made up of exchanges, like the New York Stock Exchange and the Nasdaq. Stocks are listed on a specific exchange, which brings buyers and sellers together and acts as a market for the shares of those stocks. The exchange tracks the supply and demand — and directly related, the price — of each stock. 

Bull markets vs. bear markets

Neither is an animal you’d want to run into on a hike, but the market has picked the bear as the true symbol of fear: A bear market means stock prices are falling — thresholds vary, but generally to the tune of 20% or more — across several of the indexes referenced earlier.

Younger investors may be familiar with the term bear market but unfamiliar with the experience: We’ve been in a bull market — with rising prices, the opposite of a bear market — since March 2009. That makes it the longest bull run in history.

It came out of the Great Recession, however, and that’s how bulls and bears tend to go: Bull markets are followed by bear markets, and vice versa, with both often signaling the start of larger economic patterns. In other words, a bull market typically means investors are confident, which indicates economic growth. A bear market shows investors are pulling back, indicating the economy may do so as well.
