Month by month
The stock's clearest edge over the S&P 500 lands in January (+11.3 pts); it has trailed the market most in March (−5.2 pts).
“vs S&P” is Ichor Holdings Ltd’s average for a month minus the S&P 500’s average for that same month — isolating Ichor Holdings Ltd’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, January has closed higher 60% of the time versus 67% 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
There's a real but measured seasonal tilt here, toward January — the firmest corner of the calendar, higher in 6 of 9 Januaries.
The strength looks broad-based rather than freakish: its average (+11.1%) and median (+13.2%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even January ranges by 16.3% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — January has outpaced the S&P 500 by +11.3 points on average. Few peers keep such company in January — the typical stock clears it just 53% of the time.
Only November comes anywhere near it for reliability. On the other side of the ledger, August has been the soft spot — the weakest of 3 months that average a loss (−4.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, August, and September. Its roughest month on record was a −35.9% 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.
Treat it as a tendency rather than a rule — seasonality describes the past, not a promise. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (January), its worst (August), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (January, +11.1%) has run well ahead of its worst (August, −4.1%) — the heatmap above shows how steady that gap has been year to year.
January has been the strongest, averaging +11.1% and closing higher in 6 of 9 years since 2016.
It's the weakest, averaging −4.1% — historically a soft spot, though it still varies from year to year.
