Job openings and labor turnover (JOLTS): how far markets move after the release
Job openings and labor turnover (JOLTS): across 128 releases since 2016, the Nasdaq-100 fund (QQQ) typically moved 14.9 bp in either direction in the 30 minutes after the release, against 17.5 bp in the control window (n = 128).
The typical size of the move
Over these 128 releases, against 128 control mornings, the typical 30-minute move in the Nasdaq-100 fund was 0.9 times the size of the control window's. In either direction: the study measures how much prices moved, not which way.
By fund and window
Basis points of each fund's price. Typical size is the median move with its sign removed; the middle half is the 25th to 75th percentile of the signed moves. Each window counts its own releases: a morning is left out for a fund that did not trade before a measuring point. The control is the same thirty minutes on the business day before (there is no five-minute control) and leaves out days that were themselves a release morning at that time.

How this is measured
We measured every JOLTS release from January 12, 2016 to September 1, 2026, 128 release mornings. On each one we take three exchange-traded funds, QQQ (the Nasdaq-100), SPY (the S&P 500) and TLT (long-dated Treasuries), from the last one-minute price before the 10:00 a.m. ET release to five and to thirty minutes after it. The control is the same thirty minutes on the business day before each release, leaving out a day that was itself a release morning at that time in our history. Figures are in basis points (hundredths of a percentage point): the median and the middle half (25th to 75th percentile) of the moves with their sign, and the median size of the move whichever way it went. Each window shows how many mornings it covers. We hold no consensus forecast, so no release is sorted into a beat or a miss: these figures describe how large the reaction usually is, not which way it goes. They describe what happened before and do not predict the next release.
- Each figure is a size, not a direction. We hold no consensus forecast, so we do not sort releases into beats and misses, and a large move after one release says nothing about the direction of the next one.
- Moves are in basis points of the fund's price: 100 basis points is 1%. The typical size is the median of the moves with their sign removed, so half of the measured releases moved less and half moved more. The middle half runs from the 25th to the 75th percentile of the signed moves.
- The control window is the same thirty clock minutes on the business day before each release, for the same funds, leaving out a day that was itself a release morning at that time. It is a baseline for that hour of the day, not a morning with nothing scheduled: the notes say what it still holds, such as releases we do not measure yet. Every figure carries the number of mornings it rests on (n).
- What happened before is not a forecast. Information only, not financial advice.
Notes
- The control is the same clock window on the business day before, not the minutes just before the release: a window just before a 10:00 a.m. release would include the 9:30 a.m. open, the busiest half hour of the day.
