What is the Dow Jones Industrial Average

What is the Dow Jones Industrial Average? The Dow Jones Industrial Average (DJIA), also known as the Dow Jones or simply the Dow, is a stock market index that tracks the performance of 30 large, publicly traded companies listed on the New York Stock Exchange (NYSE) and the Nasdaq. The DJIA was created in 1896 by Charles Dow, the founder of Dow Jones & Company, and Edward Jones, a statistician. It is different from the S&P 500 which tracks the performance of 500 companies.

How Does the Dow Work?

The Dow Jones Industrial Average (DJIA) is calculated using a price-weighted formula, which means that the stocks in the index are weighted based on their stock prices, rather than their market capitalization or other factors. Here’s how the calculation works:

  • Determine the total value of the 30 stocks in the index: The DJIA is calculated by adding up the stock prices of the 30 component companies in the index. This gives us the total value of all the stocks in the index.
  • Calculate the divisor: A divisor is a number that is used to adjust the DJIA for stock splits, mergers, and other corporate actions that could affect the index. The divisor is adjusted periodically to maintain continuity in the index’s historical data.
  • Divide the total value of the stocks by the divisor: The final step is to divide the total value of the stocks by the divisor. This gives us the DJIA value.

For example, if the total value of the 30 stocks in the DJIA is $1,000 and the divisor is 0.1234, then the DJIA value would be $8,099.51 (1,000 / 0.1234 = 8,099.51).

Because the DJIA is price-weighted, stocks with higher prices have a greater impact on the index’s value. This means that changes in the stock price of a high-priced stock like Apple can have a bigger effect on the index than changes in the stock price of a lower-priced stock like General Electric.

What Is the List of Companies on the Dow?

The companies included in the DJIA can change over time as the index’s managers seek to maintain their representation of the US stock market. Companies may be added or removed from the index based on a number of factors, including their size, financial stability, and reputation.
