MPLX LP is currently running 20.6% annualised volatility over the last 21 sessions. Measured against MPLX's own 13 years of daily returns rather than a market-wide average, that is the 36th percentile — on the quiet side for this stock, against a typical reading of 23.5%.

MPLX is trading -31.3% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -20.8%, and the deepest was -68.5% 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 -1.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 31st percentile — close to the gap it normally carries. Over the past year MPLX closed higher on 52% of sessions, and it is currently 1 session into a rising streak.

On November specifically: over 13 years of records, MPLX finished the month higher 7 of 13 times, with a median return of +1.2% and an average of +1.6%. Its strongest month historically has been April at +6.7% on average, its weakest March at -4.0%.

Overnight risk is measurable too: MPLX has opened more than 2% away from the prior close in 160 of 3,268 sessions (4.9% of the time), with the largest gaps running +14.1% and -8.8%.

Across the last 3 dated reports on file, MPLX moved an average of 1.2% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.8% and a largest of -2.2%.

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