Micron Technology, Inc. is currently running 43.4% annualised volatility over the last 21 sessions. Measured against MU's own 13 years of daily returns rather than a market-wide average, that is the 52nd percentile — close to its own typical level, against a typical reading of 42.5%. 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.

MU is trading -13.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -38.3%, and the deepest was -60.7% in 2015. 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 +54.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 90th percentile — a wider gap than this stock usually carries. Over the past year MU closed higher on 54% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, MU finished the month higher 7 of 13 times, with a median return of +0.3% and an average of +2.5%. Its strongest month historically has been May at +13.1% on average, its weakest March at -2.1%. 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: MU has opened more than 2% away from the prior close in 198 of 3,269 sessions (6.1% of the time), with the largest gaps running +7.4% and -10.1%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 4 dated reports on file, MU moved an average of 2.4% in the session after earnings, closing higher 3 of those 4 times, with a median move of +2.1% and a largest of +3.1%.

All figures computed from 3,270 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against MU's own 13-year history, not a peer group or index.
