What Is the Dow Jones Industrial Average?
The Dow Jones Industrial Average (DJIA) is one of the oldest and most widely followed stock market indexes in the world. It tracks 30 large, blue‑chip U.S. companies across major industries, serving as a benchmark for overall stock market performance and investor sentiment.
The index is price‑weighted, meaning companies with higher share prices have a larger influence on the index level.
