Month by month
The stock's clearest edge over the S&P 500 lands in May (+11.3 pts); it has trailed the market most in September (−8.8 pts).
“vs S&P” is Kyndryl Holdings Inc’s average for a month minus the S&P 500’s average for that same month — isolating Kyndryl Holdings Inc’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 5 years — the pattern is holding.
Figures are the typical (median) December 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
Strip the year back and a single month does the heavy lifting: December, up in 4 of 5 Decembers while the other eleven tend to blur together.
The headline flatters a touch — its +5.2% average sits well above the +2.5% a typical year delivers, the work of a few big Decembers. Crucially, the gain is the stock's own rather than a rising tide's: December has cleared the S&P 500 by +4.2 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–February forms a firm stretch that carries much of the year. On the other side of the ledger, March has been the soft spot — the weakest of 6 months that average a loss (−6.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, March, and April. Its roughest month on record was a −52.8% November in 2021 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: December aside, the stock's months offer little reliable tilt. With a short 5-year record, the signal is best held loosely.
Short answers on the stock's best month (December), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2021 its best month (December, +5.2%) has run well ahead of its worst (March, −6.6%) — the heatmap above shows how steady that gap has been year to year.
December has been the strongest, averaging +5.2% and closing higher in 4 of 5 years since 2021.
It's the weakest, averaging −6.6% — historically a soft spot, though it still varies from year to year.
