Move = the first close after the release against the close before it. A release after 4pm ET is priced by the next session; one before 9:30am ET by that day’s. Times are when the SEC accepted the 8-K (Item 2.02), which follows the press release by minutes. Closes held from Jan 14, 2026; a dash means we don't hold the closes for that report. Prior-session closes only; not a forecast, not advice.
