What & Why

The Dow Jones Industrial Average serves several critical functions.

• Market Benchmark: It provides a benchmark against which the performance of other investments can be measured. Investors often compare their portfolios to the Dow to assess their returns.
• Economic Indicator: As a reflection of the performance of 30 major companies, the Dow can be used as a general indicator of economic health. Significant increases or decreases in the Dow often reflect changes in investor confidence and economic outlook.
• Investment Strategy: The Dow helps inform investment strategies. Many investors use the Dow to guide their decisions, such as when to buy, sell, or hold stocks. The index also influences the creation of financial products like exchange-traded funds (ETFs) that track its performance.

How the Dow Works

The Dow is calculated using a price-weighted method, meaning stocks with higher prices have a greater influence on the index. The Dow's value is determined by adding up the prices of all 30 stocks and dividing by a divisor, which adjusts for stock splits and other corporate actions. The divisor ensures continuity in the index's value over time.

Companies in the Dow

The 30 companies included in the Dow are selected by a committee based on factors like company size, financial health, and industry representation. The committee aims to include a diverse group of companies that are leaders in their respective sectors. Some of the current companies included in the Dow are:

• Apple (AAPL)
• Microsoft (MSFT)
• Visa (V)
• Johnson & Johnson (JNJ)
• The Coca-Cola Company (KO)

Risks of Following the Dow

• Limited Representation: The Dow only includes 30 companies, which is a small sample of the total market. This means it may not fully represent the performance of the entire stock market.
• Price-Weighted Method: Because the Dow is price-weighted, high-priced stocks have a disproportionate impact on the index, which might skew the results.
