Understanding the Dow Jones Industrial Average (DJIA)

     

The Dow Jones Industrial Average, also known as the Dow Jones, is one of the most widely followed stock market indices in the world. It represents a snapshot of the overall health of the stock market and is used by investors, analysts, and the media to gauge the performance of the stock market.

What is the Dow Jones Industrial Average?

The Dow Jones Industrial Average is a stock market index that tracks the performance of 30 large, publicly traded companies in the United States.

The divisor is adjusted periodically to ensure that the index remains representative of the
