Dow Jones Industrial Average (DJIA)
The Dow Jones Industrial Average (DJIA), often simply referred to as “the Dow,” is one of the oldest, most commonly followed equity indices. Named after Charles Dow, the DJIA tracks 30 large, publicly-owned companies trading on the New York Stock Exchange (NYSE) and the NASDAQ. Established in 1896 by Dow Jones & Company, the index originally aimed to offer a reliable gauge of the industrial sector’s performance. Today, the DJIA serves as a barometer for the overall U.S. economy’s health and investor sentiment.
