Coherent Corp. is currently running 96.7% annualised volatility over the last 21 sessions. Measured against COHR's own 13 years of daily returns rather than a market-wide average, that is the 93rd percentile — an extreme by its own standards, against a typical reading of 44.1%.

COHR is trading -52.8% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -44.2%, and the deepest was -59.9% in 2022. The current drawdown is already deeper than this stock's typical annual low point, which puts it in the part of its range where past recoveries began, and where past declines also continued.

Price sits -32.1% from its 200-day moving average. Against every other day in its history, that gap ranks at the 2nd percentile — a narrower gap than it typically runs. Over the past year COHR closed higher on 52% of sessions, and it is currently 1 session into a rising streak.

On November specifically: over 13 years of records, COHR finished the month higher 10 of 13 times, with a median return of +3.7% and an average of +7.7%. Its strongest month historically has been January at +7.8% on average, its weakest March at -5.7%.

Overnight risk is measurable too: COHR has opened more than 2% away from the prior close in 421 of 3,268 sessions (12.9% of the time), with the largest gaps running +9.2% and -10.3%.

Across the last 3 dated reports on file, COHR moved an average of 3.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -2.4% and a largest of -4.8%.

All figures computed from 3,269 daily closes between 2013-11-06 and 2026-11-05, split-adjusted, recomputed daily. Percentiles are against COHR's own 13-year history, not a peer group or index.
