"Dow jumps 1,100 points" sounds like the biggest move of Monday's rally. It was actually the smallest of the major indexes. The Dow rose 1,104.02 points, or 2.15%, to 52,389.75 on Nov. 9, 2026. Meanwhile the S&P 500 gained 2.35%, the Nasdaq Composite 2.74% and the Nasdaq 100 3.40%.
The reason is in how the Dow is built. The explainers that turn up in a search mostly give the formula. They don't show what it means for a day like this one.
0.17: the divisor that turns dollars into points
The Dow is officially a 30-stock, price-weighted index. To get its value, you add up the share prices of all 30 companies and divide by the Dow divisor.
Some explainers describe this as taking an "average price" and then dividing by the divisor. The Trust Company of Vermont's page is one example. That's misleading. You divide the plain sum of the prices. The divisor does the averaging.
The divisor started out simple. It was 12, the number of stocks in the first average. It has been adjusted ever since to account for stock splits and changes in which companies are included. When a stock splits, its price drops, but nothing real has happened to the company. So the divisor is lowered so the index doesn't jump. Decades of those adjustments have shrunk it below 1.
The official current figure comes from S&P Dow Jones Indices, and we couldn't confirm it for Nov. 9. Working back from recent closing prices, dowjonestoday.net puts it at about 0.1688, so a $1 move in any Dow stock is worth about 5.9 points. The site says its number is derived and may differ slightly from the official one. Older explainers still use figures like 0.147, or about 6.8 points per dollar.
You can also run the math in reverse. At roughly 6 points per dollar, Monday's 1,104 points means the 30 share prices rose by a combined total of about $186, net of any that fell. That's our estimate from dowjonestoday.net's divisor, not a published figure.
2.15%: what Monday's 1,104 points actually was
Points tell you how far the index moved. Percentages tell you how big that move was. The Dow closed Friday around 51,286 (52,389.75 minus 1,104.02), so the gain works out to 2.15%.
That's a strong day, but the rest of the market did better:
| Index | Nov. 9, 2026 gain |
|---|---|
| Dow Jones Industrial Average | 2.15% |
| S&P 500 | 2.35% |
| Nasdaq Composite | 2.74% |
| Nasdaq 100 | 3.40% |

The S&P 500's 2.35% was its best day since April 8, and it got there with a gain of fewer than 200 points. Comparing point moves across indexes tells you little, because each index starts from a very different level.
10.3%: what 1,000 points used to mean
The Dow's first 1,000-point gain came in April 1999. It rose 1,002.88 points, a 10.3% gain. As the index has climbed, the same number of points has come to mean less and less:
| Date | Point gain | Percent gain |
|---|---|---|
| April 1999 | 1,002.88 | 10.3% |
| Dec. 26, 2018 | 1,086.25 | 4.98% |
| Aug. 4, 2026 | about 1,000 | about 1.7% |
| Nov. 9, 2026 | 1,104.02 | 2.15% |
The December 2018 gain was the biggest one-day point gain ever at the time. Monday's gain was slightly bigger in points but less than half as big in percentage terms. To match 1999's 10.3% from Friday's close, the Dow would need to gain about 5,300 points in one day.
That's also why 1,000-point days keep happening. By Aug. 4, 2026, the Dow had 27 sessions with 1,000-point gains. As that article puts it, 1,000 points is a 5% day at 20,000 but barely 2% at 45,000. We couldn't confirm how many have come since, so we can't say where Monday ranks.
The records show the same gap between points and percentages. The biggest one-day point gain is 2,112.98 points on March 24, 2020. The biggest one-day percentage gain is 15.34% on March 15, 1933. It goes the other way too. On Black Monday in 1987, the Dow fell just 508 points, but that was a 22.6% loss. That is still its worst percentage day.
$1 ≈ 6 points: why Nvidia can fall while the Dow jumps
In a price-weighted index, the share price is all that counts. A $100 stock counts for 10 times as much as a $10 stock, however big or small either company is. Every Dow member moves the index the same roughly 6 points for each dollar its shares move.
Nvidia has been in the Dow since November 2024, when it replaced Intel. Its market value doesn't give it extra pull in the Dow. Its influence depends only on its share price. If Nvidia slides, its drop can be outweighed by a few higher-priced Dow stocks rising by more dollars per share.
We don't have a breakdown of how many points each stock added or subtracted on Nov. 9. Working that out requires each component's closing price for the day.
8,000+: how the S&P 500 does it differently
The S&P 500 is weighted by market value, so bigger companies count for more. It also uses a divisor, but one over 8,000, according to one estimate. Under this setup, a giant like Nvidia moves the index far more than a small company does, however high or low its share price is.
For any index, divide the point change by the previous close to get the percentage. That number lets you compare one day with another, one index with another, and 2026 with 1999.
