Hewlett Packard Enterprise Company is currently running 48.2% annualised volatility over the last 21 sessions. Measured against HPE's own 11 years of daily returns rather than a market-wide average, that is the 83rd percentile — elevated for this stock, against a typical reading of 31.3%. 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.

HPE is trading -10.1% below its running peak. Across 10 full years on file, its median worst-drawdown-in-a-year was -25.8%, and the deepest was -50.5% 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 +70.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 98th percentile — a wider gap than this stock usually carries. Over the past year HPE closed higher on 53% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 12 years of records, HPE finished the month higher 4 of 12 times, with a median return of -1.7% and an average of -1.6%. Its strongest month historically has been May at +5.6% on average, its weakest October at -1.6%. 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: HPE has opened more than 2% away from the prior close in 134 of 2,762 sessions (4.9% of the time), with the largest gaps running +24.1% and -5.5%. 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, HPE moved an average of 7.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -4.7% and a largest of +9.0%.

All figures computed from 2,763 daily closes between 2015-10-19 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against HPE's own 11-year history, not a peer group or index.
