Have you ever heard the term “the Dow” on the news or in financial apps? It’s one of the most talked-about numbers in finance — but what exactly is it, and why does it matter to you?
Whether you’re completely new to investing or just want a straightforward explanation, here’s everything you need to know about:
- What the Dow Jones Industrial Average (DJIA) really is
- How it works and why it’s still a big deal
- Which companies are in it and how it impacts the economy
- Why both investors and everyday people keep an eye on it
Let’s dive in!
What Is the Dow Jones Industrial Average?
- The Dow Jones Industrial Average (DJIA) is a stock market index tracking 30 large, influential U.S. companies.
- Originally focused on industrial firms, it now includes sectors like technology, healthcare, finance, retail, and more.
- Think of it as a health check for the U.S. economy, reflecting how these big companies’ stock prices move.
- When you hear “the market is up today,” it often means the Dow went up.
A Quick History: How the Dow Got Started
- Created in 1896 by Charles Dow and Edward Jones.
- Started with 12 companies from railroads, oil, and gas sectors.
- Expanded to 20 companies in 1916, then 30 in 1928 — the number we have today.
- Has evolved through wars, economic crashes, and tech revolutions.
- Companies like Coca-Cola and Procter & Gamble joined during major economic shifts.
How Is the Dow Calculated?
- The Dow is price-weighted, meaning companies with higher stock prices impact the Dow more.
- Calculation steps:
- Add up the stock prices of all 30 companies.
- Divide by the Dow Divisor — a number adjusted for stock splits and changes.
- This is different from other indices like the S&P 500, which weight companies by market capitalization (company size).
