Dow Jones: Frequently Asked Questions

The Dow Jones Industrial Average most recently closed at 53,185.90 on August 31, 2026, a change of −374.09 (−0.70%) from the prior session. The homepage carries the current figure with full context — including how the move ranks historically — and refreshes intraday when markets are open.

No. The index level is unitless: it's the sum of 30 share prices divided by a small adjustment factor (currently about 0.168248), so the result is neither dollars nor an average price. Only changes in the level — ideally percentage changes — mean anything. The arithmetic is worked through with real prices in how the Dow is calculated.

At today's level, no: 500 points is roughly a 1% move, which markets produce routinely. The useful habit is converting points to percent before reacting — a habit this site's daily briefing automates by ranking each session against every daily move since 1992. As a rule of thumb, days beyond ±2% are genuinely uncommon; days beyond ±4% cluster almost exclusively inside crises, as the records page shows.

Thirty large U.S. companies chosen by committee — currently including Apple, Microsoft, NVIDIA, Goldman Sachs, UnitedHealth, Walmart and, since June 2026, Alphabet. The full roster with live prices, computed index weights and a profile of each member is on the Dow 30 page.

Different stocks, different weighting. The Dow holds 30 blue chips weighted by share price; the Nasdaq Composite is thousands of listings dominated by megacap tech. On days when technology diverges from the rest of the market, the two indexes split — over the last year their daily moves have correlated at only 0.83 (Dow vs S&P 500) and lower still versus the Nasdaq. See the measured comparison.

You can't buy an index, but you can buy funds that replicate it — index funds and ETFs that hold all 30 stocks in the same proportions (the largest ETF tracking the Dow trades under the ticker DIA). Costs and minimums vary by fund and broker. Note that most long-term investors use broader index funds (S&P 500 or total-market) as a core holding; a Dow fund is a narrower, blue-chip-tilted bet. Nothing on this site is investment advice — see our disclaimer.

The index is calculated continuously while U.S. exchanges are open: 9:30 a.m. to 4:00 p.m. Eastern, Monday through Friday, excluding market holidays. The day's official value is the 4:00 p.m. close. Futures on the Dow trade nearly around the clock and hint at the next open, but they are a separate instrument — the index itself sleeps overnight.

The all-time closing high in our dataset is 54,349.12, set on August 5, 2026. Whether the index is at a high right now — and how far below the peak it sits if not — is computed daily on the homepage. Every 1,000-point milestone ever crossed is dated on the milestones page.

No — it tracks prices only. The dividends its member companies pay (historically roughly two percentage points a year of extra return) never appear in the index level, which is why long-run charts of the Dow understate what a buy-and-hold investor actually earned. Separate "total return" versions of the index exist for that purpose but aren't the number you see in headlines.

An index committee at S&P Dow Jones Indices (which includes Wall Street Journal editors) makes changes by judgment, with no fixed schedule. Turnover is slow — years can pass between changes — and often arrives in clusters triggered by splits, mergers or bankruptcies. The four most recent changes are listed with context on the Dow 30 page.

The worst was Black Monday — October 19, 1987 — a 22.6% single-day collapse. In the modern era our data covers, the worst was March 16, 2020 (−12.93%) and the best days were crisis rebounds in 2008, 2020 and April 2025. Full top-ten tables, by points and by percent, recomputed daily, are on the records page.

Heritage. When Charles Dow launched the average in 1896, "industrial" distinguished factory-economy stocks from the railroads that dominated finance. The name survived even as the roster turned into a cross-section of the whole economy — today the index contains exactly one company that would have counted as heavy industry in 1896's sense (Caterpillar), and its official sector exposure is measured on the Dow 30 page. The history is covered in what is the Dow Jones.

Daily closing data from public market-data feeds, fetched and recomputed every day at build time; every statistic on the site is calculated by us from that primary series rather than copied from other websites. The full pipeline — sources, computations, update cadence, and known limitations — is documented on the About & methodology page.
