Duke Energy Corporation is currently running 12.2% annualised volatility over the last 21 sessions. Measured against DUK's own 13 years of daily returns rather than a market-wide average, that is the 18th percentile — unusually subdued by its own history, against a typical reading of 16.0%. 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.

DUK is trading -11.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -12.9%, and the deepest was -36.7% 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 -4.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 17th percentile — a narrower gap than it typically runs. Over the past year DUK closed higher on 49% of sessions, and it is currently 2 sessions into a rising streak.

On October specifically: over 13 years of records, DUK finished the month higher 10 of 13 times, with a median return of +1.9% and an average of +2.5%. Its strongest month historically has been March at +2.6% on average, its weakest February at -2.0%. 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: DUK has opened more than 2% away from the prior close in 25 of 3,267 sessions (0.8% of the time), with the largest gaps running +11.3% and -5.3%. 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, DUK moved an average of 1.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.1% and a largest of -1.8%.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against DUK's own 13-year history, not a peer group or index.
