One reading to set expectations: in 7 of Marsh and McLennan'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 MMC stock after earnings. The scores themselves — the part that turns "it moved" into "will it keep going?" — are on the member DriftLab.

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.
