NiSource Inc. is currently running 16.4% annualised volatility over the last 21 sessions. Measured against NI's own 13 years of daily returns rather than a market-wide average, that is the 31st percentile — on the quiet side for this stock, against a typical reading of 19.3%. 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.

NI is trading -15.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -14.3%, and the deepest was -30.9% 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 -7.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 9th percentile — a narrower gap than it typically runs. Over the past year NI closed higher on 51% of sessions, and it is currently 3 sessions into a rising streak.

On October specifically: over 13 years of records, NI finished the month higher 9 of 13 times, with a median return of +2.3% and an average of +1.7%. Its strongest month historically has been March at +3.3% on average, its weakest September at -1.4%. 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: NI has opened more than 2% away from the prior close in 95 of 3,267 sessions (2.9% of the time), with the largest gaps running +7.8% and -7.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 3 dated reports on file, NI moved an average of 1.5% in the session after earnings, closing higher 2 of those 3 times, with a median move of +1.1% and a largest of +1.7%.

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