Method

How the numbers are made.

How is Arcosa, Inc.'s median reaction calculated?

Every labeled ACA news event is measured from its own timestamp: the last trade before the news is the base price, and the move is read at fixed horizons — 30 minutes of trading, then the close. The median across 308 events is what this page reports. Point-in-time, zero look-ahead: no event borrows information from a later one.

What counts as a positive reaction?

Any event whose price move is above zero at the horizon, relative to the last trade before the news timestamp. 52% of ACA's measured events are up at 30 minutes; the rest close the window flat or negative.

How often is this page updated?

The news table refreshes automatically as new events are labeled and priced. The reaction medians are re-pulled in batches from the dataset — the figures here are as of 2026-08-13.

Does ACA's past reaction predict its next one?

No. These are realized facts about past events, not forecasts. They describe a distribution — they say nothing certain about any future move.
