Every economic calendar tells you what a report printed. None of them tell you what the market did next. This one measures it: for each major US release, how far the Nasdaq 100 and S&P 500 actually moved in the minutes afterwards, release by release.
Release dates and times come from the publishing agencies themselves — the Bureau of Labor Statistics, the Census Bureau, the Bureau of Economic Analysis and the Federal Reserve. Using their own schedules rather than a calendar rule matters: payroll reports have landed on dates no rule would predict, and a date that is wrong by a day measures the wrong minute of the wrong session.
Prices are one-minute bars on Nasdaq 100 and S&P 500 index CFDs. They trade around the clock, which is why they capture the 08:30 ET releases that land an hour before the equity market opens. They track the futures closely but are not the CME contracts, and every figure here is a percentage of the index level rather than a contract point.
The headline figure on each page is the swing: the highest price minus the lowest price in the thirty minutes after a release. It is deliberately not the net change. A report can leave the index exactly where it started after moving half a percent in both directions, and the net number would call that a non-event while anyone holding a position would disagree.
These are records of what happened, not forecasts. Sample sizes are shown on every page so you can judge them yourself. Consensus forecasts are not published by any agency and so are absent here. Nothing on this site is investment advice.
