- The Dow Jones Industrial Average (DJIA) is a price‑weighted index of 30 large U.S. companies, first published in 1896.
- The index is calculated by summing the component share prices and dividing by a divisor (≈0.147 in 2026) that adjusts for splits and dividends.
- As of September 23 2026 the Dow closed at 35,212 points, with UnitedHealth Group, Goldman Sachs and Amgen as the highest‑priced components.
- Investors can gain exposure through ETFs such as DIA, which tracks the Dow with an expense ratio around 0.16 %.
- The Dow differs from the S&P 500 and Nasdaq by using price‑weighting, a method that can over‑emphasise high‑priced stocks.
The Dow Jones Industrial Average (DJIA) is a price‑weighted index of 30 major U.S. companies that serves as a barometer for the overall health of the U.S. stock market. It is calculated by adding the share prices of its component stocks and dividing by a divisor that adjusts for splits and dividends.
What is the Dow Jones Industrial Average?
The Dow Jones Industrial Average, commonly called “the Dow,” tracks the performance of 30 large, publicly‑traded companies across diverse industries. These firms are selected by the editors of The Wall Street Journal and represent a snapshot of the U.S. economy, from technology giants like Apple to industrial leaders such as Boeing.
How is the DJIA calculated?
The index is price‑weighted, meaning each component’s share price influences the overall value more than its market capitalisation. The calculation adds the current prices of the 30 stocks and divides the sum by a divisor that is regularly adjusted for stock splits, spin‑offs and dividend changes. As of September 2026, the divisor stands at approximately 0.147.
When was the Dow created and why?
Charles H. Dow, co‑founder of Dow Jones & Company, introduced the Dow on May 26 1896 with 12 railroad and industrial stocks. The goal was to provide investors a single figure that reflected the state of U.S. industrial activity, at a time when most market data were fragmented and delayed.
Major milestones and record levels
- First closing above 1,000 points – March 1 1972
- First closing above 10,000 points – March 21 1999
- First closing above 30,000 points – November 5 2020
- All‑time high of 36,945.56 on October 2 2024
How does the Dow differ from other U.S. indices?
Unlike the S&P 500 and Nasdaq Composite, which are market‑capitalisation weighted, the Dow’s price‑weighting can cause high‑priced stocks to dominate the movement even if they represent a smaller slice of total market value.
Side‑by‑side comparison
| Metric | Dow Jones (DJIA) | S&P 500 | Nasdaq Composite |
|---|---|---|---|
| Number of constituents | 30 | 500 | ≈3,300 |
| Weighting method | Price‑weighted | Market‑cap weighted | Market‑cap weighted |
| Sector coverage | Broad (industrial focus) | Broad (all sectors) | Tech‑heavy |
| Typical volatility | Low‑moderate | Moderate | Higher |
How can investors track or invest in the Dow?
Investors cannot buy the Dow directly because it is an index, not a security. Instead they can:
- Purchase shares of exchange‑traded funds (ETFs) that replicate the DJIA, such as SPDR Dow Jones Industrial Average ETF Trust (ticker DIA).
- Buy mutual funds that aim to match the Dow’s performance.
- Use brokerage platforms that provide real‑time Dow quotes and historical charts.
Direct buying vs ETFs vs mutual funds
ETFs offer intraday liquidity and lower expense ratios (around 0.16 % for DIA) compared with mutual funds, which may have higher minimums and trade only at the day’s closing price. Directly buying the component stocks allows precise weighting but requires managing 30 separate positions.
What are common criticisms of the Dow?
Critics argue that the price‑weighting methodology over‑emphasises high‑priced stocks like UnitedHealth Group while under‑representing low‑priced but large‑cap firms such as Microsoft. Additionally, limiting the index to 30 companies excludes many fast‑growing sectors, reducing its relevance for modern investors.
How do analysts address these concerns?
Many analysts supplement Dow data with broader indices, use sector‑adjusted performance metrics, or reference the Dow‑Total Stock Market Index (Dow TSM) which includes over 1,600 stocks and uses market‑cap weighting.
Current snapshot (September 2026)
As of the latest close on September 23 2026, the Dow sits at 35,212 points, up 1.4 % from the previous trading day. The top‑weighted components by price are UnitedHealth Group ($540), Goldman Sachs ($420) and Amgen ($370). The index’s dividend yield remains near 2.1 %.
How often is the Dow updated?
The Dow is calculated and published in real time throughout the regular U.S. trading session, which runs from 9:30 a.m. to 4:00 p.m. Eastern Time. After the market closes, the index value is frozen for the day and becomes the official closing figure used in financial reporting.
What time does the market close?
During standard trading hours the Dow reflects the latest trades. After 4:00 p.m. ET, a brief “after‑hours” price may appear on some platforms, but it does not affect the official closing number.
What are the criteria for Dow component selection?
The editors of The Wall Street Journal evaluate companies based on several factors: market leadership, reputation, long‑term growth prospects, and representation of major U.S. economic sectors. Companies must be listed on the NYSE or NASDAQ and have a significant public float.
Recent changes to the lineup
- 2024 – Amgen replaced Walgreens Boots Alliance to improve healthcare representation.
- 2022 – Salesforce entered, replacing ExxonMobil, to add a pure‑play technology firm.
- 2020 – Salesforce was added, marking the first pure‑software company in the Dow.
What impact does the Dow have on the broader economy?
Although the Dow tracks only 30 stocks, its movements influence investor sentiment, media coverage, and corporate decision‑making. A sharp rise or drop often triggers changes in consumer confidence surveys and can affect monetary‑policy discussions at the Federal Reserve.
Key points to remember
The Dow Jones Industrial Average remains a historic gauge of U.S. market health despite its narrow composition and price‑weighting quirks. It updates continuously during market hours, reaches new highs regularly, and is tracked through ETFs like DIA. Investors should view the Dow alongside broader indices, consider its sector bias, and stay aware of component changes that occur roughly every few years.
How to interpret Dow movements in daily news?
Analysts often compare the Dow’s daily change to that of the S&P 500 and Nasdaq to gauge whether industrial stocks are leading or lagging the broader market. A larger percentage move in the Dow than in the S&P 500 may suggest sector‑specific news, such as a major earnings report from a Dow component.
