Dow 30 (Dow Jones Industrial Average)

Definition

The Dow 30, officially known as the Dow Jones Industrial Average (DJIA), is a stock market index that tracks the performance of 30 influential large-cap companies listed on stock exchanges in the United States. It serves as a prominent gauge of the overall health of the U.S. stock market and economy. The Dow 30 is price-weighted, meaning companies with higher stock prices have a greater impact on the index’s movements.

Key Features:

• Price Calculation: The Dow 30 value is calculated by summing the prices of its 30 constituent stocks and dividing by the Dow Divisor.
• Constituents: The companies in the index include well-established corporations from diverse sectors, excluding transportation and utilities.
• ETF Accessibility: Individuals can invest in the Dow via the SPDR Dow Jones Industrial Average ETF (DIA).

Example of Calculation

If the stocks of the 30 companies sum up to $3,000 and the Dow Divisor is 0.145 (it changes based on stock splits and dividends), the DJIA would be: $$ \text{Dow 30} = \frac{3,000}{0.145} \approx 20,689.66 $$
