The Dow Jones Industrial Average is a price-weighted U.S. stock index tracking 30 large blue-chip companies.
The Dow Jones Industrial Average (DJIA), often simply referred to as the Dow, is a prominent stock market index that measures the stock performance of 30 large, publicly-listed companies on the New York Stock Exchange (NYSE) and the NASDAQ. It is one of the oldest and most watched indices in the world, providing a snapshot of the health and direction of the broader stock market and economy.
The DJIA is a price-weighted index, meaning that companies with higher stock prices have a greater influence on the index’s movements. The calculation involves adding the prices of the 30 stocks and dividing by a divisor that accounts for stock splits, spinoffs, and other adjustments.
The DJIA is used by:
If the sum of the prices of the 30 stocks is $3,000 and the divisor is 0.147, the DJIA would be:
DJIA = 3000 / 0.147 ≈ 20408
