Month by month
The stock's clearest edge over the S&P 500 lands in November (+10.2 pts); it has trailed the market most in June (−10.6 pts).
“vs S&P” is Sylvamo Corp’s average for a month minus the S&P 500’s average for that same month — isolating Sylvamo Corp’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 100% of the time versus 100% across the last 5 years — the pattern is holding.
Figures are the typical (median) November return and how often it rose — the last 5 years versus the last 5(the heatmap’s default window). This verdict stays anchored to that 5-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
This is a stock you can almost set a calendar by, and November is the anchor — it has closed higher in all 5 Novembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+12.5%) and median (+11.7%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: November's returns vary by just 4.3% year to year, and even its worst November in 5 years lost only 8.6% — the gentlest downside anywhere on its calendar. Better still, that strength is the stock's own and not just a buoyant market — November has outpaced the S&P 500 by +10.2 points on average. Few peers keep such company in November — the typical stock clears it just 62% of the time.
November anchors a run, too: the July-through-November window has been the stock's reliable season. At the other end of the calendar, March has been the soft spot — the weakest of 3 months that average a loss (−2.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in June, December, and March. Its roughest month on record was a −35.7% June in 2022 — a reminder of how hard even a seasonal name can fall.
November has now closed higher 5 years running.
For a stock this dependable in November, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 5-year record, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2021 its best month (November, +12.5%) has run well ahead of its worst (March, −2.4%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +12.5% and closing higher in all 5 years on record since 2021.
It's the weakest, averaging −2.4% — historically a soft spot, though it still varies from year to year.
