Long-term chart of Dow Jones Index - Dow Jones Industrial Average (since 1900) is available on this page, plus its components, description and more.

Dow Jones Index or to be exact in the name, the Dow Jones Industrial Average, also known as the Dow Jones, the Industrial Average, the Dow 30, or simply the Dow, is one of the oldest and mostly closely-watched stock indices all over the world.

Provider and Calculation of Index

Dow Jones Index

Dow Jones Index is calculated and published by Dow Jones Indexes (, who is a leading full-service index provider that develops, maintains and licenses indexes for use as benchmarks and as the basis of investment products. Dow Jones Indexes offers more than 130,000 equity indexes as well as fixed-income and alternative indexes, including measures of hedge funds, commodities and real estate.

Dow is price-weighted, and to compensate for the effects of stock splits and other adjustments, it is currently a scaled average. The value of the Dow is not the actual average of the prices of its component stocks, but rather the sum of the component prices divided by a divisor, which changes whenever one of the component stocks has a stock split or stock dividend, so as to generate a consistent value for the index.

Although Dow compiled the index to gauge the performance of the industrial sector within the American economy, the index's performance continues to be influenced by not only corporate and economic reports, but also by domestic and foreign political events.
