Vaults entering a crowd went on to underperform matched vaults that did not by -18.01% at the worst point of the following 20 days. Shuffling the event dates produces a path that extreme 89% of the time, so this is not yet distinguishable from noise.
That share rests on 140 shuffles of the 250 asked for, because the job reached its time limit. It can be read to about 0.7 percentage points and no finer.
What the window is. Every event here is a crowd that formed while we were watching, which is 54 days of cluster history. The returns either side of an event are the venue’s own published account-value history and reach back much further, so the series is long and the study is not: crowds formed before we began have no event date and are not in this table.
