Watts Water Technologies Inc. Class A is currently running 16.1% annualised volatility over the last 21 sessions. Measured against WTS's own 13 years of daily returns rather than a market-wide average, that is the 12th percentile — unusually subdued by its own history, against a typical reading of 23.2%. 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.

WTS is trading -7.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -17.9%, and the deepest was -39.7% in 2022. 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 +12.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 70th percentile — a somewhat wider gap than its own norm. Over the past year WTS closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, WTS finished the month higher 8 of 13 times, with a median return of +2.1% and an average of +1.7%. Its strongest month historically has been November at +5.3% on average, its weakest March 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: WTS has opened more than 2% away from the prior close in 131 of 3,267 sessions (4.0% of the time), with the largest gaps running +8.1% and -12.0%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

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