Month by month
Across the year the stock has stayed close to the S&P 500 — no single month stands out as a real edge.
“vs S&P” is Klarna Group plc’s average for a month minus the S&P 500’s average for that same month — isolating Klarna Group plc’s own seasonal edge from broad market drift.
Reality check
Not enough recent October history to say whether the pattern still holds.
Figures are the typical (median) October return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
The seasonal story is really one month's story — October. It has closed higher in all 1 Octobers, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+0.9%) and median (+0.9%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: October's returns vary by just 0.0% year to year, and even its worst October in 1 years lost only 0.9% — the gentlest downside anywhere on its calendar. Set against the S&P 500, mind, October is close to a wash — the gain mirrors the market more than it beats it. Few peers keep such company in October — the typical stock clears it just 53% of the time.
No other month comes close to matching it — the rest of the calendar is unremarkable by comparison. The weaker half of the year is plainer: November has been the soft spot — the weakest of 3 months that average a loss (−15.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in November, September, and December. Its roughest month on record was a −15.8% November in 2025 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in October, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 1-year record, the signal is best held loosely.
Short answers on the stock's best month (October), its worst (November), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (October, +0.9%) has run well ahead of its worst (November, −15.8%) — the heatmap above shows how steady that gap has been year to year.
October has been the strongest, averaging +0.9% and closing higher in its one year on record since 2025.
It's the weakest, averaging −15.8% — historically a soft spot, though it still varies from year to year.
