What is Dow Jones and the Dow Jones Companies?

The Dow Jones Industrial Average (DJIA), commonly referred to as the Dow, is one of the most widely recognized stock market indices in the world. But what is Dow Jones, and why does it hold such significance in the financial world? The Dow serves as a benchmark for the performance of major U.S. companies and provides insights into the health of the stock market and the broader economy. The Dow Jones companies are selected carefully to represent the strength of American business and industry.

In this comprehensive article, we will explore the history of the Dow Jones Industrial Average, the methodology behind its calculations, its role as an economic indicator, and the companies that comprise this prestigious index. Along the way, we will incorporate key statistics to illustrate the Dow’s long-standing importance in financial markets.

A Historical Perspective: The Evolution of the Dow Jones Industrial Average

The Dow Jones Industrial Average was first introduced in 1896 by Charles Dow and Edward Jones, the founders of Dow Jones & Company. At its inception, the index consisted of just 12 companies, primarily from the industrial sector. These firms included major players in railroads, oil, and steel—industries that were the backbone of the U.S. economy at the time.

The first recorded value of the Dow Jones Industrial Average was 40.94 points. Over the next century, as the U.S. economy expanded and diversified, so did the Dow Jones companies. By 1928, the index had grown to 30 companies, which remains its current structure.

Major Milestones in Dow History

• 1929 – The Great Depression: The Dow peaked at 381.17 points in September 1929 before crashing, losing nearly 90% of its value over the next three years.
• 1987 – Black Monday: The Dow fell 22.6% in a single day on October 19, the largest percentage drop in history.
• 1999 – The Tech Boom: The Dow crossed the 10,000-point milestone for the first time.
• 2008 – Financial Crisis: The Dow fell from 14,000+ points in 2007 to under 7,000 points in 2009.
• 2021 – Post-Pandemic Growth: The Dow reached an all-time high of 36,799 points in January 2022.

Today, the Dow remains one of the most closely watched indicators of the stock market, offering a historical perspective on long-term economic trends.

The Dow’s Unique Calculation Methodology

Unlike many other stock indices, the Dow uses a price-weighted methodology rather than a market capitalization-weighted approach. This means that companies with higher stock prices have a greater influence on the index’s movement, regardless of their overall market value.

[su_note note_color=”#ffffff” text_color=”#000000″ radius=”10″]For example: If a company with a stock price of $400 increases by 5%, it will have a much larger effect on the Dow than a company with a stock price of $50, even if the latter has a larger total market capitalization.[/su_note]

This methodology has been criticized because it can create distortions. To address this issue, the Dow uses a Dow Divisor, which is adjusted whenever companies undergo stock splits or other corporate actions to ensure continuity in the index’s calculation.

Why Only 30 Companies?

One of the most frequently asked questions about the Dow Jones Industrial Average is why it includes only 30 companies while other indices, such as the S&P 500, track hundreds of firms. The reason lies in the selection process.

The Dow Jones companies are handpicked by a committee at S&P Dow Jones Indices based on several factors:

• Market Representation: The companies must represent key sectors of the U.S. economy.
• Industry Leadership: The companies must be leaders in their industries.
• Public Interest: They should be widely followed by investors and have a history of sustained growth.
• U.S.-Based: Companies must be headquartered in the U.S.

The Dow Jones companies change infrequently, but when shifts occur, they reflect transformations in the economy. For example, in 2020, ExxonMobil, Pfizer, and Raytheon Technologies were removed, and Salesforce, Amgen, and Honeywell were added to reflect the increasing importance of technology and healthcare.
