Month by month
The stock's clearest edge over the S&P 500 lands in January (+4.5 pts); it has trailed the market most in July (−1.6 pts).
“vs S&P” is Stryker Corporation’s average for a month minus the S&P 500’s average for that same month — isolating Stryker Corporation’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, January has closed higher 60% of the time versus 80% across the last 10 years — the pattern is weakening.
Figures are the typical (median) January 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. January stands out, higher in 8 of 10 Januaries, but it heads a clutch of months that pull the year reliably upward.
Its average (+4.3%) and median (+3.8%) 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: January has cleared the S&P 500 by +4.5 points above the index. That consistency sets it apart from the field, where the average stock manages January only about 53% of the time.
The strength clusters rather than stands alone — November–June forms a firm stretch that carries much of the year. The weaker half of the year is plainer: October is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the stock has trailed the S&P 500 in July, October, and March. Its roughest month on record was a −15.3% March in 2020 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, January's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: January aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (January), its worst (October), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (January, +4.3%) has run well ahead of its worst (October, +0.1%) — the heatmap above shows how steady that gap has been year to year.
January has been the strongest, averaging +4.3% and closing higher in 8 of 10 years since 2016.
It's the weakest month, but it has still averaged a small gain (+0.1%) — quiet rather than genuinely bad.
