The Dow Jones Industrial Average (DJIA) is one of the oldest and probably best-known stock indexes in the world. It is composed of 30 U.S.-based "blue chip" stocks, which change periodically based on market fluctuations and the fortunes of the individual companies. Seven of the 10 largest U.S. companies ranked by market capitalisation are members of the DJIA; Amazon.com, Facebook and Google were not members as of 24 March 2020.
However, all 10 are components of the S&P 500, which tracks the performance of 500 large-cap American stocks and is probably the most widely-followed stock index.
