Western Midstream Partners, LP is currently running 31.1% annualised volatility over the last 21 sessions. Measured against WES's own 13 years of daily returns rather than a market-wide average, that is the 55th percentile — close to its own typical level, against a typical reading of 28.9%.

WES is trading -35.5% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -24.2%, and the deepest was -85.8% 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 -4.5% 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 WES closed higher on 52% of sessions, and it is currently 4 sessions into a falling streak.

On November specifically: over 13 years of records, WES finished the month higher 8 of 13 times, with a median return of +0.6% and an average of +4.8%. Its strongest month historically has been April at +14.5% on average, its weakest March at -4.7%.

Overnight risk is measurable too: WES has opened more than 2% away from the prior close in 296 of 3,268 sessions (9.1% of the time), with the largest gaps running +19.1% and -10.5%.

Across the last 3 dated reports on file, WES moved an average of 1.7% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.8% and a largest of -3.4%.

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