What ACM does after the print
The implied move above is the size options price for the report. How the move unfolds afterwards is a separate question, and DriftLab tracks it for AECOM across every past report: the follow-through score (does the earnings-day direction continue or reverse?), the gap-fill probability (how often the opening gap gets filled), the PEAD score (post-earnings drift strength), the reaction path of every release out to sixty sessions, and the current run drawn against the projected drift into the next report. One reading to set expectations: in 9 of AECOM's last 15 reports the stock was further in the direction of its earnings-day close thirty sessions later. The full record, report by report, is on ACM stock after earnings. The scores themselves — the part that turns "it moved" into "will it keep going?" — are on the member DriftLab. Read what the metrics mean in the PEAD guide.
What is an implied move?
The implied move is the size of the earnings-day move the options market is pricing in, derived from the at-the-money straddle expiring just after the report. It is a market price, not a forecast.

After the report, options typically reprice sharply — the IV crush calculator shows what an option is worth once implied volatility resets.
