What is the Dow Jones Industrial Average?
The Dow Jones Industrial Average (DJIA) is a stock market index that measures the performance of 30 large, publicly-owned companies listed on stock exchanges in the United States. These companies are leaders in their respective industries and represent a significant portion of the U.S. economy. The DJIA is often referred to simply as "the Dow."
Key Features of the DJIA
- Price-Weighted Index: The DJIA is a price-weighted index, meaning that companies with higher stock prices have a greater impact on the index's overall performance.
- 30 Companies: The index consists of 30 blue-chip companies, which are known for their stability and reputation in the market.
- Benchmark for Market Performance: The DJIA is widely used as a benchmark for assessing the performance of the stock market and the economy.
History of the DJIA
The Dow Jones Industrial Average was first calculated on May 26, 1896, by Charles Dow and Edward Jones. Initially, it included just 12 companies, primarily in the industrial sector. The index has undergone numerous changes, with the number of companies increasing to 30 in 1928.
Significant Milestones
- 1906: DJIA first reaches 100 points, marking a significant milestone.
- 1929: The index hits its highest point before the stock market crash.
- 1987: The DJIA experiences the largest single-day percentage drop in history.
- 2000: The DJIA surpasses 10,000 points for the first time.
- 2020: The DJIA falls sharply due to the COVID-19 pandemic but recovers quickly.
How Does the DJIA Work?
The calculation of the Dow Jones Industrial Average is based on the stock prices of its 30 component companies. Unlike other indices that use market capitalization, the DJIA is price-weighted, meaning that the stock price of each company directly influences the index's value.
Calculation Method
The formula for calculating the DJIA involves the sum of the stock prices of all 30 companies divided by a divisor. The divisor is adjusted for stock splits, dividends, and other factors to ensure the index remains consistent over time. This method means that a change in the stock price of a high-priced stock will have a more significant effect on the DJIA than a change in a lower-priced stock.
Components of the DJIA
The DJIA consists of 30 prominent companies from various sectors, including technology, healthcare, finance, and consumer goods. Below is a table listing the current components of the DJIA along with their respective stock symbols:
| Company Name | Stock Symbol |
