The Dow Jones Industrial Average (DJIA), often simply referred to as “the Dow,” is a stock market index that tracks the performance of 30 of the largest and most influential publicly traded companies in the United States. It is one of the most widely watched stock market indices globally, serving as a barometer for the overall health of the U.S. economy.
Understanding the Dow Jones
The Dow is a price-weighted index, meaning that companies with higher stock prices have a greater influence on the overall index value. This differs from market-capitalization-weighted indices like the S&P 500, where a company’s weight is determined by its market capitalization (share price multiplied by the number of outstanding shares).

Price Weighting: As mentioned earlier, the Dow is price-weighted. This means that stock price movements of companies with higher share prices have a greater impact on the index.
Dow Divisor: A constantly adjusted number used in the calculation of the Dow to account for stock splits, mergers, and other corporate actions.

What is the Dow Jones Index?

Price-Weighted Average: Unlike market-capitalization-weighted indexes like the S&P 500, the Dow’s price-weighting methodology gives higher-priced stocks greater influence.
Divisor: This factor is adjusted to maintain the index’s continuity despite stock splits, spin-offs, and other corporate events.
