Entergy Corporation is currently running 15.1% annualised volatility over the last 21 sessions. Measured against ETR's own 13 years of daily returns rather than a market-wide average, that is the 24th percentile — unusually subdued by its own history, against a typical reading of 18.8%. 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.

ETR is trading -13.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -13.7%, and the deepest was -42.0% 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 -2.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 26th percentile — a narrower gap than it typically runs. Over the past year ETR closed higher on 48% of sessions, and it is currently 2 sessions into a falling streak.

On October specifically: over 14 years of records, ETR finished the month higher 11 of 14 times, with a median return of +3.8% and an average of +4.7%. Its strongest month historically has been October at +4.7% on average, its weakest September at -1.7%. 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: ETR has opened more than 2% away from the prior close in 66 of 3,268 sessions (2.0% of the time), with the largest gaps running +21.7% and -12.0%. 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, ETR moved an average of 2.6% in the session after earnings, closing higher 2 of those 3 times, with a median move of +3.1% and a largest of +4.6%.

All figures computed from 3,269 daily closes between 2013-10-16 and 2026-10-15, split-adjusted, recomputed daily. Percentiles are against ETR's own 13-year history, not a peer group or index.
