SBA Communications Corporation is currently running 33.4% annualised volatility over the last 21 sessions. Measured against SBAC's own 13 years of daily returns rather than a market-wide average, that is the 86th percentile — elevated for this stock, against a typical reading of 22.9%. 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.

SBAC is trading -53.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.5%, and the deepest was -38.5% 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 -4.7% 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 SBAC closed higher on 46% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, SBAC finished the month higher 9 of 13 times, with a median return of +2.6% and an average of +2.3%. Its strongest month historically has been April at +3.8% on average, its weakest September at -4.9%. 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: SBAC has opened more than 2% away from the prior close in 90 of 3,267 sessions (2.8% of the time), with the largest gaps running +6.6% and -7.9%. 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, SBAC moved an average of 4.2% in the session after earnings, closing higher 3 of those 3 times, with a median move of +4.2% and a largest of +4.7%.
