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

What’s next · results

Six trading days after each results filing (SEC 8-K, Item 2.02). IRM reports during the trading day, so day 1 is that day’s close. 3 of 4 times, day 6 ended on the same side as day 1.
