Mid-America Apartment Communities, Inc. is currently running 15.2% annualised volatility over the last 21 sessions. Measured against MAA's own 13 years of daily returns rather than a market-wide average, that is the 26th percentile — on the quiet side for this stock, against a typical reading of 18.6%. 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.

MAA is trading -49.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -14.0%, and the deepest was -42.7% in 2020. 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 -11.1% from its 200-day moving average. Against every other day in its history, that gap ranks at the 10th percentile — a narrower gap than it typically runs. Over the past year MAA closed higher on 44% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, MAA finished the month higher 6 of 13 times, with a median return of -0.7% and an average of +0.5%. Its strongest month historically has been November at +2.5% on average, its weakest September at -3.2%. 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: MAA has opened more than 2% away from the prior close in 64 of 3,267 sessions (2.0% of the time), with the largest gaps running +10.9% and -9.9%. 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, MAA moved an average of 1.7% in the session after earnings, closing higher 0 of those 3 times, with a median move of -2.1% and a largest of -2.5%.

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