Month by month
The stock's clearest edge over the S&P 500 lands in September (+7.1 pts); it has trailed the market most in October (−3.8 pts).
“vs S&P” is Teck Resources Ltd Class B’s average for a month minus the S&P 500’s average for that same month — isolating Teck Resources Ltd Class B’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, December has closed higher 80% of the time versus 80% across the last 10 years — the pattern is holding.
Figures are the typical (median) December return and how often it rose — the last 5 years versus the last 10(the heatmap’s default window). This verdict stays anchored to that 10-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. December stands out, higher in 8 of 10 Decembers, but it heads a clutch of months that pull the year reliably upward.
Its average (+4.0%) and median (+9.9%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 10.5% spread). Crucially, the gain is the stock's own rather than a rising tide's: December has cleared the S&P 500 by +3.0 points above the index. That consistency sets it apart from the field, where the average stock manages December only about 58% of the time.
The strength clusters rather than stands alone — November–January forms a firm stretch that carries much of the year. On the other side of the ledger, October has been the soft spot — the only month to average an outright loss (−2.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, March, and May. Its roughest month on record was a −27.9% March in 2020 — a reminder of how hard even a seasonal name can fall.
At its steadiest, December strung together 7 straight positive years. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
The takeaway is less about when to buy than what to expect: December aside, the stock's months offer little reliable tilt. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (December), its worst (October), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (December, +4.0%) has run well ahead of its worst (October, −2.8%) — the heatmap above shows how steady that gap has been year to year.
December has been the strongest, averaging +4.0% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −2.8% — historically a soft spot, though it still varies from year to year.
