The Dow Jones Industrial Average (DJIA), often just called "the Dow," is a stock market index that tracks 30 large, publicly owned companies based in the United States. It's one of the oldest and most commonly followed indices, giving a general idea of how the stock market is doing. However, because it only includes 30 companies, it's not as broad a measure as other indices like the [[S&P 500]]. Still, changes in the Dow are often seen as an indicator of the overall health of the [[United States of America (USA)]] economy. See also [[Nasdaq]]
