Month by month
The stock's clearest edge over the S&P 500 lands in July (+4.1 pts); it has trailed the market most in January (−4.8 pts).
“vs S&P” is Plexus Corp’s average for a month minus the S&P 500’s average for that same month — isolating Plexus Corp’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 60% of the time versus 80% across the last 10 years — the pattern is weakening.
Figures are the typical (median) November 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. November stands out, higher in 8 of 10 Novembers, but it heads a clutch of months that pull the year reliably upward.
A typical November brings +3.2%, a shade under the +4.5% average. It is among its calmest months, too, its returns swinging least from year to year (a 5.4% spread). Crucially, the gain is the stock's own rather than a rising tide's: November has cleared the S&P 500 by +2.2 points above the index. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
The strength clusters rather than stands alone — October–December forms a firm stretch that carries much of the year. On the other side of the ledger, January has been the soft spot — the only month to average an outright loss (−5.0%), and the edge isn't year-round — the stock has trailed the S&P 500 in January, March, and April. Its roughest month on record was a −20.7% January in 2022 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, November's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: November aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (November), its worst (January), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (November, +4.5%) has run well ahead of its worst (January, −5.0%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +4.5% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −5.0% — historically a soft spot, though it still varies from year to year.
