Pembina Pipeline Corp. Ordinary Shares (Canada) is currently running 21.0% annualised volatility over the last 21 sessions. Measured against PBA's own 13 years of daily returns rather than a market-wide average, that is the 45th percentile — close to its own typical level, against a typical reading of 22.2%. 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.

PBA is trading -5.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -19.2%, and the deepest was -71.4% 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 +6.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 68th percentile — a somewhat wider gap than its own norm. Over the past year PBA closed higher on 55% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 13 years of records, PBA finished the month higher 6 of 13 times, with a median return of -0.4% and an average of -0.5%. Its strongest month historically has been April at +5.6% on average, its weakest September at -2.7%. 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: PBA has opened more than 2% away from the prior close in 170 of 3,267 sessions (5.2% of the time), with the largest gaps running +17.1% and -10.0%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against PBA's own 13-year history, not a peer group or index.
