The Dow Jones Industrial Average (DJIA), often referred to simply as the Dow, is one of the oldest and most well-known stock market indexes in the world. It serves as a key indicator of the overall health and performance of the stock market and the broader economy, particularly in the United States.
The Dow is often used as a barometer of the U.S. stock market's performance. It reflects investor sentiment and is closely watched by financial professionals, economists, and individual investors to gauge the economic outlook.
