QUALCOMM Incorporated is currently running 52.2% annualised volatility over the last 21 sessions. Measured against QCOM's own 13 years of daily returns rather than a market-wide average, that is the 88th percentile — elevated for this stock, against a typical reading of 29.8%. 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.

QCOM is trading -29.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -27.7%, and the deepest was -44.9% 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 +4.1% from its 200-day moving average. Against every other day in its history, that gap ranks at the 62nd percentile — a somewhat wider gap than its own norm. Over the past year QCOM closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, QCOM finished the month higher 9 of 14 times, with a median return of +2.1% and an average of +1.7%. Its strongest month historically has been May at +6.5% on average, its weakest March at -3.1%. 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: QCOM has opened more than 2% away from the prior close in 79 of 3,268 sessions (2.4% of the time), with the largest gaps running +7.7% and -9.7%. 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, QCOM moved an average of 4.1% in the session after earnings, closing higher 2 of those 3 times, with a median move of +0.5% and a largest of -8.5%.

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