How the options market is pricing it
The September 25, 2026 straddle marks $189.93 to $207.67 as the range the options market is paying for into the print, with ATM implied vol at 63% set to drain the morning after. A reaction inside that band hands the edge to premium sellers; a break outside it rewards premium buyers. Historically CTAS has moved 5.30% on earnings against the ±4.46% now implied, so the market is pricing this print cheaper than the recent average. Which side of that trade is right depends on the number, the guidance and where positioning unwinds.
