Rentokil Initial plc American Depositary Shares (each representing five (5) Ordinary Shares) is currently running 21.4% annualised volatility over the last 21 sessions. Measured against RTO's own 13 years of daily returns rather than a market-wide average, that is the 27th percentile — on the quiet side for this stock, against a typical reading of 25.1%. 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.

RTO is trading -53.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.8%, and the deepest was -42.8% in 2023. 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 -30.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 0th percentile — a narrower gap than it typically runs. Over the past year RTO closed higher on 46% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, RTO finished the month higher 8 of 13 times, with a median return of +1.5% and an average of +0.3%. Its strongest month historically has been April at +4.6% on average, its weakest September at -4.1%. 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: RTO has opened more than 2% away from the prior close in 542 of 3,266 sessions (16.6% of the time), with the largest gaps running +12.2% and -16.7%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,267 daily closes between 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against RTO's own 13-year history, not a peer group or index.
