What is the Dow Jones Industrial Average (DJIA)?
The Dow Jones Industrial Average (DJIA), sometimes referred to as simply the Dow, is one of several well-known stock market indices. The DJIA was created by Charles Dow, founder of the Journal, to measure the daily stock price movements of 30 large, publicly-owned U.S. companies.
How Does the Dow Jones Industrial Average (DJIA) Work?
The Dow Jones Industrial Average was originally intended to measure the movements of companies within the heavy industry, like construction companies and businesses dealing with heavy products. Today, however, that name is strictly historical; very few of the index's 30 companies have anything to do with industrial goods.
The DJIA is price-weighted, meaning that the movement in stocks with higher prices impacts the Dow more than stocks with lower prices. The Dow's daily value is not the true average of the 30 stocks' prices, but is actually the sum of the prices divided by the Dow divisor, which is adjusted in cases of stock splits, spinoffs and other structural changes to keep the weighting constant and maintain continuity.
The Dow is one of the most closely watched tracking stock market activity. Although it was created to track the performance of the U.S. industrial sector, it now is seen as a proxy for general market conditions.benchmarks
