What Is the Dow 30? Companies In It, Significance
The Dow 30, officially known as the Dow Jones Industrial Average (DJIA), is one of the most well-known stock market indices in the United States. It provides a snapshot of the performance of 30 major, publicly traded companies, representing a diverse array of industries. This article explores what the Dow 30 is, the companies included in it, and its significance in the financial markets.
1. What Is the Dow 30?
a. Definition
The Dow 30, or the Dow Jones Industrial Average, is a stock market index that measures the performance of 30 large, publicly traded companies in the U.S. It is one of the oldest and most widely recognized indices, established in 1896 by Charles Dow and Edward Jones. The DJIA is often used as a benchmark for the overall health of the U.S. stock market and economy.
b. Calculation
The Dow 30 is a price-weighted index, meaning that stocks with higher prices have a greater influence on the index’s movements than stocks with lower prices. The DJIA is calculated by summing the prices of the 30 component stocks and then dividing by a divisor, which is adjusted to account for stock splits, dividends, and other factors to maintain continuity in the index.
