What is the Dow Jones Industrial Average?
The Dow Jones Industrial Average, commonly referred to as the Dow, is a stock market index that tracks the performance of 30 large, publicly-owned companies in the United States. These companies are leaders in their respective industries and are often considered blue-chip stocks. The DJIA is price-weighted, meaning that companies with higher stock prices have a greater influence on the index's overall value.
Key Features of the DJIA
- Represents 30 major companies in the U.S. economy.
- Price-weighted index, impacting from higher stock prices.
- Used as a barometer for U.S. economic health.
History of the Dow Jones Industrial Average
The DJIA was created by Charles Dow and Edward Jones in 1896, initially consisting of just 12 companies. Over the years, the index has evolved, expanding to its current total of 30 companies. The DJIA has undergone several changes, including the addition and removal of companies to reflect the changing landscape of the U.S. economy.
Significant Milestones in DJIA History

- 2000: DJIA reaches a high of 11,722.98.
- 2020: The index surpasses 30,000 for the first time.
How is the DJIA Calculated?
The calculation of the Dow Jones Industrial Average is based on a price-weighted formula. This means that the index is calculated by adding the stock prices of all 30 companies and then dividing that total by a divisor, which is adjusted for stock splits, dividends, and other corporate actions. The formula can be summarized as follows:
DJIA = (Sum of stock prices) / Divisor
Understanding the Divisor
The divisor is a crucial component in calculating the DJIA, as it ensures that the index remains consistent over time despite changes in the stock prices of its components. The divisor is not a fixed number and is adjusted as needed.
Components of the DJIA
The DJIA consists of 30 prominent companies from various sectors, including technology, healthcare, finance, and consumer goods. Some of the notable companies in the index include:
| Company | Ticker Symbol | Industry |
|---|---|---|
| Apple Inc. | AAPL | Technology |
| Microsoft Corp. | MSFT | Technology |
| Boeing Co. | BA | Aerospace |
| Coca-Cola Co. | KO | Beverages |
| Johnson & Johnson | JNJ | Healthcare |
