How to read this. The “Day 1 price move” is the stock’s percentage change from the close before the report to the close after it — the report day itself for before-open prints, the next trading day for after-close prints. Avg / Median move and Typical swing (standard deviation) summarise that reaction across this company’s last 30 reports; % closed up is how often it finished green. Actual Day 1 is the number that really printed for this report (fills in once the report is in the past). Dates from our data provider, refreshed 2026-11-08; reports can be rescheduled. History, not a forecast — not investment advice.
