Crown Castle Inc. is currently running 55.0% annualised volatility over the last 21 sessions. Measured against CCI's own 13 years of daily returns rather than a market-wide average, that is the 99th percentile — an extreme by its own standards, against a typical reading of 20.8%. 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.

CCI is trading -61.8% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -19.0%, and the deepest was -43.9% 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 -3.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 29th percentile — a narrower gap than it typically runs. Over the past year CCI closed higher on 48% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, CCI finished the month higher 6 of 13 times, with a median return of -1.5% and an average of -0.7%. Its strongest month historically has been November at +3.5% on average, its weakest September at -4.7%. 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: CCI has opened more than 2% away from the prior close in 82 of 3,266 sessions (2.5% of the time), with the largest gaps running +7.9% and -9.1%. 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 CCI's own 13-year history, not a peer group or index.
