Dow Jones Industrial Average

The Dow Jones Industrial Average (DJIA) or “the Dow” is a price-weighted stock market index. It is composed of 30 large U.S. corporations. It was created by the Dow Jones & Company, the publisher of The Wall Street Journal in 1896.

The Dow has a long track record and is a popular index along with the S&P 500. The disadvantage of the Dow is that it only has 30 companies so it is not a broad stock index. The S&P 500 has 500 companies and it is the standard for U.S. large cap stocks.
