Dow Jones Industrial Average

The Dow Jones Industrial Average (DJIA), commonly referred to as the Dow, is a stock market index that tracks the performance of 30 large, publicly traded companies listed on stock exchanges in the United States. Created by financial journalist Charles Dow and statistician Edward Jones, the index was first published on 26 May 1896 with 12 industrial companies. It is maintained by S&P Dow Jones Indices, a joint venture between S&P Global, CME Group, and News Corp. Despite its name, the DJIA today includes companies from a wide range of industries and is regarded as one of the most recognized indicators of the U.S. stock market.

Unlike most major stock indices, the Dow Jones Industrial Average is a price-weighted index, meaning that companies with higher share prices have a greater influence on the index regardless of their market capitalization. The index is calculated using the Dow Divisor, a value adjusted over time to account for stock splits, spin-offs, and other corporate actions, thereby maintaining continuity in the index's value. Its constituents represent sectors including information technology, financial services, healthcare, consumer goods, industrials, energy, and telecommunications. The composition of the index is periodically reviewed by a committee to ensure that it reflects the changing structure of the U.S. economy.

The Dow Jones Industrial Average serves as a widely cited benchmark for assessing investor sentiment and the overall performance of large-cap U.S. companies. Although it includes only 30 constituents and is less broadly representative than the S&P 500 or the NASDAQ Composite, it remains one of the most influential stock market indices in global finance. The DJIA is extensively referenced by investors, economists, policymakers, and the financial media and forms the basis for numerous exchange-traded funds (ETFs), futures contracts, options, and other investment products.
