Month by month
The stock's clearest edge over the S&P 500 lands in November (+11.4 pts); it has trailed the market most in May (−6.0 pts).
“vs S&P” is Knife River Corporation’s average for a month minus the S&P 500’s average for that same month — isolating Knife River Corporation’s own seasonal edge from broad market drift.
Reality check
Over the last 3 years, November has closed higher 100% of the time versus 100% across the last 3 years — the pattern is holding.
Figures are the typical (median) November return and how often it rose — the last 3 years versus the last 3(the heatmap’s default window). This verdict stays anchored to that 3-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Dependability is the through-line here. November stands out, higher in all 3 Novembers, but it heads a clutch of months that pull the year reliably upward.
Its average (+13.7%) and median (+12.4%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Crucially, the gain is the stock's own rather than a rising tide's: November has cleared the S&P 500 by +11.4 points above the index. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
A few other months pull their weight: January, June, and July have also closed higher more often than not. At the other end of the calendar, May has been the soft spot — the weakest of 2 months that average a loss (−5.3%), and the edge isn't year-round — the stock has trailed the S&P 500 in May, October, and April. Its roughest month on record was a −16.8% October in 2025 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: November aside, the stock's months offer little reliable tilt. With a short 3-year record, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (May), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2023 its best month (November, +13.7%) has run well ahead of its worst (May, −5.3%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +13.7% and closing higher in all 3 years on record since 2023.
It's the weakest, averaging −5.3% — historically a soft spot, though it still varies from year to year.
