Month by month
The stock's clearest edge over the S&P 500 lands in May (+7.3 pts); it has trailed the market most in April (−2.7 pts).
“vs S&P” is Logitech International SA’s average for a month minus the S&P 500’s average for that same month — isolating Logitech International SA’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, May has closed higher 80% of the time versus 70% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) May 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. May stands out, higher in 7 of 10 Mays, but it heads a clutch of months that pull the year reliably upward.
Its average (+8.0%) and median (+8.9%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That reliability comes with real swings, mind — even May ranges by 11.5% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: May has cleared the S&P 500 by +7.3 points above the index. That consistency sets it apart from the field, where the average stock manages May only about 55% of the time.
A few other months pull their weight: January, March, and July have also closed higher more often than not. On the other side of the ledger, February has been the soft spot — the weakest of 2 months that average a loss (−2.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, February, and November. Its roughest month on record was a −17.4% October in 2018 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Mays run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: May aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (May), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (May, +8.0%) has run well ahead of its worst (February, −2.6%) — the heatmap above shows how steady that gap has been year to year.
May has been the strongest, averaging +8.0% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −2.6% — historically a soft spot, though it still varies from year to year.
