The Williams Companies, Inc. is currently running 39.8% annualised volatility over the last 21 sessions. Measured against WMB's own 13 years of daily returns rather than a market-wide average, that is the 84th percentile — elevated for this stock, against a typical reading of 24.4%.

WMB is trading -16.0% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -25.2%, and the deepest was -64.2% in 2015. 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 -7.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 19th percentile — a narrower gap than it typically runs. Over the past year WMB closed higher on 50% of sessions, and it is currently 2 sessions into a falling streak.

On November specifically: over 13 years of records, WMB finished the month higher 8 of 13 times, with a median return of +0.9% and an average of +2.0%. Its strongest month historically has been April at +6.5% on average, its weakest December at -4.6%.

Overnight risk is measurable too: WMB has opened more than 2% away from the prior close in 168 of 3,268 sessions (5.1% of the time), with the largest gaps running +9.6% and -10.9%.

Across the last 3 dated reports on file, WMB moved an average of 1.2% in the session after earnings, closing higher 3 of those 3 times, with a median move of +1.4% and a largest of +1.8%.

All figures computed from 3,269 daily closes between 2013-11-06 and 2026-11-05, split-adjusted, recomputed daily. Percentiles are against WMB's own 13-year history, not a peer group or index.
