Teledyne Technologies Incorporated is currently running 15.2% annualised volatility over the last 21 sessions. Measured against TDY's own 13 years of daily returns rather than a market-wide average, that is the 17th percentile — unusually subdued by its own history, against a typical reading of 21.0%. The distinction matters because a number that looks calm for one stock is turbulent for another, and the absolute figure on its own tells you neither.

TDY is trading -11.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -17.8%, and the deepest was -48.9% in 2020. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits -2.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 19th percentile — a narrower gap than it typically runs. Over the past year TDY closed higher on 51% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, TDY finished the month higher 9 of 14 times, with a median return of +1.6% and an average of +1.4%. Its strongest month historically has been November at +5.4% on average, its weakest December at -0.4%. Seasonality is a weak signal on its own — a decade is a small sample and regimes change — but it is a real distribution rather than a rule of thumb.

Overnight risk is measurable too: TDY has opened more than 2% away from the prior close in 99 of 3,268 sessions (3.0% of the time), with the largest gaps running +5.9% and -14.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 3 dated reports on file, TDY moved an average of 0.2% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.0% and a largest of -0.3%.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against TDY's own 13-year history, not a peer group or index.
