Pool Corporation is currently running 25.3% annualised volatility over the last 21 sessions. Measured against POOL's own 13 years of daily returns rather than a market-wide average, that is the 54th percentile — close to its own typical level, against a typical reading of 24.3%. 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.

POOL is trading -72.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.2%, and the deepest was -48.4% in 2022. The current drawdown is already deeper than this stock's typical annual low point, which puts it in the part of its range where past recoveries began — and where past declines also continued.

Price sits -22.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 4th percentile — a narrower gap than it typically runs. Over the past year POOL closed higher on 46% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, POOL finished the month higher 6 of 13 times, with a median return of -0.8% and an average of +0.9%. Its strongest month historically has been November at +3.7% on average, its weakest August at -1.0%. 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: POOL has opened more than 2% away from the prior close in 112 of 3,267 sessions (3.4% of the time), with the largest gaps running +8.6% and -15.3%. 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, POOL moved an average of 1.1% in the session after earnings, closing higher 2 of those 3 times, with a median move of +1.5% and a largest of +1.7%.

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