The EarningsWatcher Lens on ROST
Where the priced move sits. Options price ±7.9%. Against ROST's own ten-year record of earnings-day peak moves, that is above the median (±6.1%) but inside what the last ten years treated as ordinary — the 80th-percentile line is ±9.3%.
Recent versus long history. For ROST, the recent regime is louder than the long one: ±8.3% over the last two years against ±7.2% over ten. Today's priced move is between the two — under the two-year figure, over the ten-year one.
The base rate. In the 18 ROST reports with a recorded implied move, the realised peak exceeded what options had priced 11 times (61%) — history here has favoured the buyers of movement. That is a description of the past, not a forecast of this print.
The last print. Aug 20, 2026: options priced ±7.9%; the stock closed +4.4% with an intraday peak of +6.5% — inside the priced range.
What this does not say. None of the above carries a direction. The implied move is the size of the move options are pricing, in either direction, and the history is how big past moves were — not which way the next one goes.
