The Dow Jones Industrial Average (DJIA) is a stock market index that measures the performance of 30 large publicly traded companies in the United States. It is one of the oldest and most widely followed indices in the world, and is often used as a barometer of the overall health of the US stock market and economy. The DJIA is calculated as the sum of the stock prices of the 30 component companies, divided by a divisor which is adjusted over time to account for stock splits and other factors. It was created by Charles Dow in 1896 and is named after Dow and his business partner, Edward Jones.
