How the Nasdaq 100 reacts to CPI, measured over 38 releases
Next release Tuesday, 10 Nov 2026 at 08:30 ET All scheduled dates →
The Consumer Price Index measures the change in prices paid by urban consumers for a basket of goods and services. The core reading, which strips out food and energy, is published in the same release.
How this compares
Of the 8 scheduled releases measured here, this one moves the Nasdaq 100 more than any other. Its median half-hour range is 0.71%, against 0.67% for the jobs report and 0.26% for retail sales - the quietest of the set.
The direction is not even: 26 of 37 finished higher half an hour on. That is a tendency in the record, not a rule about the next one.
Close to half the move arrives at once - 46% of the half-hour's range comes in the first five minutes.
The widest single reaction measured was 2.27%, on 2024-04-10. Releases that printed in the same minute as another report on this site are excluded from these figures, since the move belongs to both and to neither.
What the record shows
- When the figure printed above the forecast, the Nasdaq 100 finished the half hour lower 7 of 8 times.
- When the figure printed below the forecast, the Nasdaq 100 finished the half hour higher 9 of 11 times.
- The market goes quiet ahead of it. The hour before the print has a median range of 0.22%, against 0.71% in the thirty minutes after - 3.3 times as much travel in half the time.
- The travel is lopsided upward: a median 0.31% at the best point of the half hour against 0.24% at the worst.
- It does not finish at thirty minutes. Two hours out the median distance from the release price is 0.50%, against 0.29% at the half hour.
Measured on the Nasdaq 100, over every release on this site with at least 12 of its own on record, and excluding any that printed in the same minute as another report here. Each line is a count of what happened, not a forecast of what will: the table below holds every release the figures are drawn from, and some of these counts rest on a dozen observations or fewer. A median is what usually happened, not what happens next.

Does the first move keep going?
The first move is where the Nasdaq 100 sat five minutes after CPI, above or below the release price. Later, each release either kept going (same side, further away), held but gave some back (same side, closer to the release price) or reversed (back across it). 38 releases.
| After | Kept going | Held, gave some back | Reversed |
|---|---|---|---|
| 30 minutes | 16 of 38 (42%) | 15 of 38 (39%) | 7 of 38 (18%) |
| 1 hour | 11 of 38 (29%) | 19 of 38 (50%) | 8 of 38 (21%) |
| 2 hours | 17 of 38 (45%) | 8 of 38 (21%) | 13 of 38 (34%) |
Split by the first move, one hour on: when the first five minutes went up, the index was still above the release price in 21 of 22; when they went down, it was back above the release price in 7 of 16.
Counts of what happened on the index CFD, not odds for the next release. With a few dozen releases one or two prints move every percentage noticeably. Each row looks at one moment only, not the path in between. A reading exactly at the release price counts as reversed and an equal distance as gave some back; a release missing that reading drops out of that row only. Releases that shared their minute with another report are included.
After CPI: trend or reversal?
Did the first five minutes decide the day’s direction, all the way to the 16:00 ET close?
Trend: the 16:00 ET close was on the same side of the release price as the 5-minute mark. Reversal: it closed on the other side. Neither says what happened in between. Past counts, not odds for the next release.
Through the day, all 38 releases
Every release, drawn relative to its first move
Flipped so every line starts upward, whichever way the index went: above the centre line means on the first move’s side, not that the index rose. The latest release actually went down first. 4 of 38 lines run past ±2.1% and are cut at the edge.
Every CPI release since Aug 2023 with a full day of data, 38 so far, on the Nasdaq 100 index CFD (one-minute bid candles), updated after each new one closes. A release whose first five minutes ended exactly flat is left out; a close exactly at the release price would count as a reversal (none so far). Releases that shared their minute with another report are included. The S&P 500 row is the same count on the S&P 500: its own first five minutes, against its official 16:00 close, 37 releases. The ordinary-day mark: on 579 weekdays with none of these eight releases at 08:30 ET, the first five minutes held to the close 313 times (54%), measured on CME Nasdaq 100 micro futures from 1 Aug 2023 to 23 Sep 2026 with the same rule. A different instrument and a slightly shorter period than the bars above, and other reports at that time were not excluded. Counts of what happened, not a forecast.

Nasdaq 100
Across 38 releases, Nasdaq 100 moved a typical 0.72% from high to low in the thirty minutes after the print. The widest was 2.27%, on 10 Apr 2024. It finished that half hour higher 27 times out of 38. The net move is consistently smaller than the swing - a median of 0.30% against 0.72% of travel - which is what a price that jumps and comes back looks like in numbers.

Printed is the headline figure as it read on the day - for price indexes the seasonally adjusted change from the prior month, not the twelve-month rate, and not restated for revisions published later. Forecast is the consensus expectation going in. ▲ marks a print above that forecast and ▼ below it; which of those is good news depends on the report. A dash means the figure could not be established from a source this site trusts, and nothing is estimated to fill the gap.

Questions people ask about CPI
How much does the Nasdaq 100 move after CPI?
Across 38 releases the Nasdaq 100 moved a median 0.72% from high to low in the first thirty minutes. The widest reaction was 2.27%, on 10 Apr 2024. It finished the half hour higher 27 times out of 38.
What time is Consumer Price Index released, and when is the next one?
Bureau of Labor Statistics publishes it at 08:30 ET, monthly. The next one is Tuesday 10 Nov 2026 at 08:30 ET.
Does the first move after CPI hold?
In 79% of the 38 releases measured, the Nasdaq 100 was still on the same side of the release price at sixty minutes as it was at five minutes. The other 21% reversed.
Which moves more after CPI, the Nasdaq 100 or the S&P 500?
The Nasdaq 100. Median thirty-minute swing: Nasdaq 100 0.72% over 38 releases, S&P 500 0.53% over 37. Each index is measured on its own record, so the two counts can differ.
Is the reaction to CPI over in thirty minutes?
By this measure, mostly yes. The median distance from the release price is 0.30% at thirty minutes and 0.28% at sixty, so the index was typically closer to the release price an hour in than it was at the half hour. That compares two moments, not the path between them.
How this is measured
The reference price is the last print before the release minute. Every figure on this page is the distance from that price, as a percentage, using one-minute bars. “Swing” is the highest price minus the lowest price in the thirty minutes after the release - not the net change, which is where a price ended up rather than how far it travelled to get there.
Release dates come from the Bureau of Labor Statistics's own published schedule, so an unusual date is a real one rather than a guess from a calendar rule. Prices are Nasdaq 100 and S&P 500 index CFDs, which trade around the clock and therefore cover the 08:30 ET releases that land before the equity market opens. They track the futures closely but are not the CME contracts, and every figure is a percentage of the index level, not a contract point.
Past reactions are a record, not a forecast. Nothing here is investment advice.
