CenterPoint Energy, Inc. is currently running 22.1% annualised volatility over the last 21 sessions. Measured against CNP's own 13 years of daily returns rather than a market-wide average, that is the 67th percentile — a little above its own norm, against a typical reading of 19.1%. 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.

CNP is trading -16.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -16.8%, and the deepest was -55.5% 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 -8.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 12th percentile — a narrower gap than it typically runs. Over the past year CNP closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, CNP finished the month higher 7 of 13 times, with a median return of +0.1% and an average of +1.7%. Its strongest month historically has been April at +3.3% on average, its weakest February at -1.9%. 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: CNP has opened more than 2% away from the prior close in 87 of 3,267 sessions (2.7% of the time), with the largest gaps running +11.6% and -9.8%. 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, CNP moved an average of 1.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.3% and a largest of -2.7%.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against CNP's own 13-year history, not a peer group or index.
