Why Everyone Talks About the Dow Jones
Every time you watch financial news, you’ll hear, “The Dow Jones rose 200 points today.”
But what exactly is the Dow Jones, why does it move, and why do investors still care after more than a century?
The Dow Jones Industrial Average (DJIA) is one of the most recognized indicators of the U.S. stock market’s health. It represents 30 of the largest publicly traded companies in the United States — firms that collectively influence the global economy.
This guide breaks down the Dow Jones from every angle — what it is, how it’s calculated, which companies it includes, why it moves, and how you can interpret it as a beginner investor.
What Exactly Is the Dow Jones Industrial Average (DJIA)?
The Dow Jones Industrial Average (DJIA), often simply called “the Dow,” is a stock market index that tracks the performance of 30 major U.S. companies listed on the New York Stock Exchange (NYSE) and the NASDAQ.
It was created in 1896 by Charles Dow and Edward Jones, the founders of Dow Jones & Company (which also publishes The Wall Street Journal).
Today, the index is maintained by S&P Dow Jones Indices, a joint venture between S&P Global, the CME Group, and News Corp (the parent of The Wall Street Journal).
In simple terms, the Dow shows how large, established U.S. companies are performing — a snapshot of corporate America’s overall health.
A Brief History of the Dow Jones
The Dow Jones has seen the entire evolution of the U.S. economy — from railroads to robots.
Key historical milestones:
| Year | Event | Significance |
| 1896 | Dow Jones created | Initially tracked 12 industrial companies |
| 1929 | Great Depression | Dow lost nearly 90% of its value |
| 1987 | Black Monday crash | Largest one-day percentage drop in history |
| 2008 | Global financial crisis | Dow fell below 7,000 points |
| 2020 | COVID-19 crash | Lost 37% in weeks, then rebounded |
| 2024 | Breaks 40,000 points | Reflects AI and tech-led market optimism |
The Dow started with 12 companies, many in steel, oil, and manufacturing. Today, it has 30 companies across tech, finance, health care, retail, and more — showing how America’s economy has shifted from industry to innovation.
How Is the Dow Jones Calculated?
Unlike most modern indices (like the S&P 500), which are market-cap weighted, the Dow is price-weighted.
That means a company’s influence on the Dow is determined by its stock price, not its overall size.
Formula:
[
\text{Dow Jones} = \frac{\text{Sum of all 30 stock prices}}{\text{Dow Divisor}}
]
The Dow Divisor is a special number adjusted whenever companies split shares, merge, or change. It ensures the index remains consistent over time.
Example:
If a $200 stock rises by $2, and a $50 stock rises by $2, the higher-priced stock affects the Dow four times more.
This weighting method means price movements of expensive stocks (like Apple or UnitedHealth) move the Dow more than cheaper ones — even if the cheaper ones have a larger market cap.
The Dow Divisor (as of 2025)
The Dow Divisor is approximately 0.1517, meaning a $1 change in the combined price of the 30 stocks moves the Dow by about 6.59 points.
Which Companies Are in the Dow Jones?
The Dow represents a cross-section of U.S. industry leaders. Here are some key 2025 constituents (partial list):
| Company | Ticker | Sector |
| Apple Inc. | AAPL | Technology |
| Microsoft Corp. | MSFT | Technology |
| Boeing Co. | BA | Aerospace |
| JPMorgan Chase & Co. | JPM | Financials |
| McDonald’s Corp. | MCD | Consumer |
| Coca-Cola Co. | KO | Consumer |
| UnitedHealth Group | UNH | Health Care |
| Procter & Gamble | PG | Consumer Staples |
| Visa Inc. | V | Financials |
| Walt Disney Co. | DIS | Media & Entertainment |
💡 Did you know? The Dow’s list changes over time. Old-line companies like General Electric or ExxonMobil have been replaced as the U.S. economy evolved.
The selection of these companies is not random — a committee from S&P Dow Jones Indices chooses them based on reputation, stability, and representation of key economic sectors.
Why Investors Care About the Dow Jones
The Dow is often referred to as the “pulse of the stock market.”
Here’s why investors still follow it in 2025:
- Media reference: Headlines like “Dow falls 300 points” instantly convey market mood.
- Psychological benchmark: Big round numbers (like 40,000) affect investor sentiment.
- Economic indicator: It reflects business confidence in large U.S. companies.
- Historical continuity: With over 125 years of data, it’s invaluable for long-term analysis.
However, it has limitations:
- Only 30 companies (vs. 500 in the S&P 500).
- Price-weighted, not market cap-weighted.
- Limited exposure to smaller growth sectors.
So, while the Dow gives a broad feel for blue-chip performance, it doesn’t tell the whole story of the U.S. market.
Dow Jones vs. S&P 500 vs. Nasdaq Composite
| Index | Number of Stocks | Weighting | Focus |
| Dow Jones (DJIA) | 30 | Price-weighted | Large, established firms |
| S&P 500 | 500 | Market-cap weighted | Broad U.S. market |
| Nasdaq Composite | 3,000+ | Market-cap weighted | Tech-heavy firms |
✅ Key takeaway: The Dow shows stability and legacy. The S&P 500 shows breadth. The Nasdaq shows innovation.
