Booking Holdings Inc. is currently running 30.2% annualised volatility over the last 21 sessions. Measured against BKNG's own 13 years of daily returns rather than a market-wide average, that is the 63rd percentile — a little above its own norm, against a typical reading of 26.3%. 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.

BKNG is trading -30.9% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.9%, and the deepest was -44.8% 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 11th percentile — a narrower gap than it typically runs. Over the past year BKNG closed higher on 49% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, BKNG finished the month higher 8 of 14 times, with a median return of +1.5% and an average of +2.0%. Its strongest month historically has been February at +4.4% on average, its weakest September at -2.1%. 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: BKNG has opened more than 2% away from the prior close in 134 of 3,268 sessions (4.1% of the time), with the largest gaps running +11.4% and -8.2%. 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, BKNG moved an average of 4.1% in the session after earnings, closing higher 2 of those 3 times, with a median move of +1.3% and a largest of -6.4%.
