Texas Instruments Incorporated is currently running 29.0% annualised volatility over the last 21 sessions. Measured against TXN's own 13 years of daily returns rather than a market-wide average, that is the 68th percentile — a little above its own norm, against a typical reading of 24.7%. 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.

TXN is trading -15.0% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -19.4%, and the deepest was -30.9% 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 +11.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 68th percentile — a somewhat wider gap than its own norm. Over the past year TXN closed higher on 50% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, TXN finished the month higher 7 of 14 times, with a median return of +0.0% and an average of -0.6%. Its strongest month historically has been May at +5.3% on average, its weakest October at -0.6%. 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: TXN has opened more than 2% away from the prior close in 91 of 3,268 sessions (2.8% of the time), with the largest gaps running +7.4% and -7.0%. 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, TXN moved an average of 3.0% in the session after earnings, closing higher 2 of those 3 times, with a median move of +1.5% and a largest of +6.9%.

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