The Dow Jones Industrial Average (often just “the Dow”) is made up of 30 big, well‑known U.S. companies, and it’s a price‑weighted index, meaning higher‑priced stocks have more influence on its level than lower‑priced ones.

Quick Scoop: What makes up the Dow Jones?

  • It includes 30 large, established companies (“blue chips”) across major sectors like technology, finance, healthcare, consumer goods, and industry.
  • These companies trade on major U.S. stock exchanges such as the NYSE and Nasdaq.
  • The list is not fixed forever: a small committee (linked to S&P Dow Jones Indices and The Wall Street Journal) can add or remove companies to keep the index representative of the U.S. economy.
  • Unlike many other indices (like the S&P 500), the Dow is price‑weighted : a company with a higher share price moves the index more than a company with a lower share price, regardless of their total market value.

Examples of the kinds of companies in the Dow

As of the most recent public lists, the Dow includes a mix such as:

  • Tech and chips: Apple, Microsoft, Nvidia, Cisco, Salesforce
  • Finance: JPMorgan Chase, Goldman Sachs, American Express, Visa, Travelers
  • Healthcare: UnitedHealth Group, Johnson & Johnson, Merck, Amgen
  • Industrials and materials: Boeing, Caterpillar, 3M, Honeywell, Sherwin‑Williams
  • Consumer brands and retail: McDonald’s, Coca‑Cola, Procter & Gamble, Walmart, Nike
  • Energy and telecoms: Chevron, Verizon

These names can change over time when the committee decides to swap one company for another to better reflect current market leadership.

How the Dow is actually calculated (brief)

  • Take the sum of the prices of all 30 component stocks.
  • Divide by a special number called the Dow divisor (currently less than 1), which is adjusted whenever things like stock splits or spin‑offs happen so that those events don’t artificially move the index.

So when people say “the Dow is up 300 points today,” they’re really talking about how this price‑weighted basket of 30 big U.S. companies has moved as a group.
