DJIA

The Dow Jones Industrial Average (DJIA), commonly known as "the Dow," is one of the oldest and most widely recognized stock market indices in the world. Created in 1896 by Charles Dow, it tracks 30 prominent publicly-traded companies in the United States and serves as a key indicator of the overall health of the U.S. stock market and economy.

Overview

Unlike most modern indices, the DJIA is a price-weighted index, meaning that stocks with higher share prices have more influence on the index's movements, regardless of the company's total market capitalization. This unique methodology makes it different from market-cap weighted indices like the S&P 500.

Price-Weighted Methodology

The DJIA uses a price-weighted calculation method, which has several implications:

  • Stock Price Impact: A $1 change in a higher-priced stock has more impact than a $1 change in a lower-priced stock
  • Divisor Adjustment: The index uses a divisor that is adjusted for stock splits, spinoffs, and component changes to maintain continuity
  • Market Cap Independence: Company size doesn't directly affect its weight in the index

  • Historical Significance: Over 125 years of data and market history
  • Brand Recognition: Most widely quoted market indicator
  • Sector Diversity: Represents multiple sectors of the U.S. economy
  • Quality Companies: Components are leaders in their respective industries

Limitations

  • Limited Scope: Only 30 companies vs. 500 in the S&P 500
  • Price-Weighting Issues: Methodology may not accurately reflect economic importance
  • Less Representative: Doesn't capture the broader market as well as cap-weighted indices
  • Subjective Selection: Component changes are made by committee, not formula

How to Invest

Investors can gain exposure to the DJIA through:

  1. ETFs: SPDR Dow Jones Industrial Average ETF (DIA) is the most popular
  2. Index Funds: Mutual funds that track the DJIA
  3. Futures and Options: Dow futures (YM) for advanced traders
  4. Individual Stocks: Direct investment in component companies

Component Selection Process

The DJIA components are selected by the editors of The Wall Street Journal. Selection criteria include:

  • Reputation of the company
  • Sustained growth
  • Interest to a large number of investors
  • Representation of the U.S. economy

Changes to the index are infrequent but occur when necessary to maintain its relevance as a market barometer.

The Dow Jones Industrial Average has witnessed and survived:

  • 1929 Stock Market Crash: Lost 89% of its value by 1932

Despite these challenges, the DJIA has consistently recovered and reached new highs, demonstrating the resilience of the U.S. economy and stock market.

  • Size: 30 companies (DJIA) vs. 500 companies (S&P 500)
  • Weighting: Price-weighted vs. market-cap weighted
  • Coverage: Less representative vs. ~80% of market cap
  • Correlation: High correlation (~95%) in long-term movements

When to Track the DJIA

The DJIA is particularly useful for:
