Month by month
The stock's clearest edge over the S&P 500 lands in May (+1.4 pts); it has trailed the market most in March (−5.6 pts).
“vs S&P” is Sensata Technologies Holding NV’s average for a month minus the S&P 500’s average for that same month — isolating Sensata Technologies Holding NV’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 60% of the time versus 70% across the last 10 years — the pattern is weakening.
Figures are the typical (median) July 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
Strip the year back and a single month does the heavy lifting: July, up in 7 of 10 Julys while the other eleven tend to blur together.
Its average (+3.5%) and median (+4.0%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 5.2% spread), and even its worst July in 10 years lost only 4.7% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: July has cleared the S&P 500 by +1.3 points above the index. Some of that is a strong month market-wide, mind — July rises for about 61% of stocks — so the tendency is real if not unique.
A few other months pull their weight: May, November, and December have also closed higher more often than not. On the other side of the ledger, April 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 March, October, and February. Its roughest month on record was a −29.8% March in 2020 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, July's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: July aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (July), its worst (April), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (July, +3.5%) has run well ahead of its worst (April, −0.1%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +3.5% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −0.1% — historically a soft spot, though it still varies from year to year.
