Bank Nova Scotia Halifax Pfd 3 is currently running 24.0% annualised volatility over the last 21 sessions. Measured against BNS's own 13 years of daily returns rather than a market-wide average, that is the 82nd percentile — elevated for this stock, against a typical reading of 17.3%. 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.

BNS is trading -5.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.4%, and the deepest was -42.7% 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 +11.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 81st percentile — a wider gap than this stock usually carries. Over the past year BNS closed higher on 56% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 13 years of records, BNS finished the month higher 9 of 13 times, with a median return of +1.0% and an average of -0.1%. Its strongest month historically has been November at +3.5% on average, its weakest March at -1.3%. 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: BNS has opened more than 2% away from the prior close in 86 of 3,267 sessions (2.6% of the time), with the largest gaps running +6.8% and -10.1%. 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 BNS's own 13-year history, not a peer group or index.
