A story on the same day is not a cause, and a group move is not proof either. Group: the median of DCI, CECO and PPIH that day, the largest companies in FTEK’s SEC industry; “moved with FTEK” means the same direction and at least half the size.

Before the next report: what the first day after the last four did

Six trading days after each results filing (SEC 8-K, Item 2.02). FTEK reports after the close, so day 1 is the next close. Each time, day 6 ended on the same side as day 1.
