What Is the Dow Jones Industrial Average DJIA?

For more details on how we protect your information, please refer to our Privacy Policy. This means that it does not include many small-cap stocks or companies from all industries, such as utilities and transportation. As a result, the DJIA may not fully reflect the entire U.S. economy.

The DJIA was designed to serve as a proxy for the health of the broader U.S. economy. Often referred to simply as the Dow, it is one of the most-watched stock market indexes in the world. While the Dow includes a range of companies, all can be described as blue chip companies with consistently stable earnings. Charles Dow had the vision to create a benchmark that would project general market conditions and thus help investors bewildered by fractional dollar changes. It was a revolutionary idea at the time, but its implementation was simple. To calculate the first average, Dow added up the stock prices and divided by 11—the number of stocks included in the index.

How Investors Use the Dow Jones Industrial Average

For example, Apple is one of the largest companies in the world, with a market cap typically in the $3 trillion range. But in the Dow, which weights companies based on share price, it doesn’t even make the top 10. The DJIA launched in 1896 with just 12 companies, primarily in the industrial sector. Since then, it’s changed many times—the very first came three months after the 30-component index launched. The first large-scale change was in 1932 when eight stocks in the Dow were replaced.

About the Editorial Team

This means that the price of a stock can significantly impact the Dow Jones, even if the company’s market capitalization is not as large as others. The DJIA’s methodology of calculating an index is known as the price-weighted method. This can create some unique situations, such as a company with a smaller market cap than other companies in the index having a larger weight because its share price is higher. Stock splits have a particularly large impact on price-weighted indexes for this reason. Companies that become less relevant are replaced with those that better reflect current trends.

The DJIA is a stock market index that tracks the performance of 30 large, publicly-owned “blue-chip” companies trading on the New York Stock Exchange (NYSE) and the Nasdaq. The DJIA debuted on May 26, 1896, making it one of the oldest and most followed stock market indexes in the world. The main limitations include its price-weighted method and its representation of only 30 companies, which may not fully capture the broader U.S. market. Today, it comprises 30 major companies from various sectors, including technology, healthcare, finance, and consumer goods.

A committee reviews these criteria quarterly, making changes as needed. Because of the fragmented, global nature of today’s market, many feel the Dow is not an appropriate indicator of the overall economy. The number of companies in the original Dow Jones Industrial Average. This average eventually evolved into the Transportation Average. It wasn’t until May 26, 1896, that Dow split transportation and industrials into two different averages, creating the Dow Jones Industrial Average. Companies are periodically removed or added to ensure the index remains a relevant representation of the U.S. economy.

For instance, a company may be removed from the index when its market capitalization drops because of financial distress. Now, let’s say that one of the stocks in the IMA average trades at $100 but undergoes a two-for-one split, reducing its stock price to $50. If our divisor remains unchanged, the calculation for the average would give us 95 ($950 ÷ 10). This would not be accurate because the stock split merely changed the price, not the value of the company.

To demonstrate how this use of the divisor works, we will create an index, the Investopedia Mock Average (IMA). The IMA is composed of 10 stocks, which total $1,000 when their stock prices are added together. The Dow Divisor is a constantly adjusted figure that prevents one-off events—like stock splits or changes in component companies—from artificially distorting the index’s value.
