Marriott International, Inc. is currently running 18.7% annualised volatility over the last 21 sessions. Measured against MAR'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 23.3%. 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.

MAR is trading -8.9% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.3%, and the deepest was -61.3% in 2020. 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 +4.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 42nd percentile — close to the gap it normally carries. Over the past year MAR closed higher on 49% of sessions, and it is currently 2 sessions into a rising streak.

On October specifically: over 12 years of records, MAR finished the month higher 8 of 12 times, with a median return of +2.9% and an average of +3.6%. Its strongest month historically has been November at +6.9% on average, its weakest March at -3.5%. 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: MAR has opened more than 2% away from the prior close in 101 of 3,262 sessions (3.1% of the time), with the largest gaps running +7.6% and -6.9%. 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, MAR moved an average of 1.2% in the session after earnings, closing higher 0 of those 3 times, with a median move of -0.8% and a largest of -2.5%.

All figures computed from 3,263 daily closes between 2013-10-21 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against MAR's own 13-year history, not a peer group or index.
