COHR max pain by expiry
Coherent's max pain for 2026-Oct-30 is 250.00, 19.3% above the last price. It is the strike at which the calls and puts open for that expiry would pay out the least in total, computed from open interest. Price sometimes drifts toward it in the final session because of dealer hedging; treat it as a reference level, not a target. How max pain is calculated.

|---|---|---|---|
| 2026-Oct-30 Fri | 250.00 | +19.3% | 1.07 |

COHR put/call ratio
The put/call ratio for the 2026-Oct-30 expiry is 1.07: close to even between puts and calls. Readings well below 0.7 are often read as complacent and above 1.2 as fearful, and extremes are sometimes taken as contrarian signals, but on index products like SPY a high ratio is normal because puts are bought as insurance. It is a sentiment gauge, not a direction call. What the ratio measures and what it does not, or compare it with every tracked stock's put/call ratio today.

Reading the COHR expected move table
Each row is one expiry. The shaded band is the one-standard-deviation range the option chain implies for COHR on that date: the market gives roughly a two-in-three chance that COHR closes inside it and a one-in-three chance it closes outside. The black tick is the last traded price, 209.49. The diamond is max pain, the strike where option holders would collect the least if the stock settled there.
The range widens with time because uncertainty compounds with the square root of time: the 2026-Nov-20 range (±22.39%) is wider than the 2026-Oct-30 range (±10.97%) even though the daily volatility behind both is the same. Read the methodology for the formulas, or the guide to what the expected move means in practice.
