Month by month
The stock's clearest edge over the S&P 500 lands in November (+14.2 pts); it has trailed the market most in September (−9.0 pts).
“vs S&P” is 10X Genomics Inc’s average for a month minus the S&P 500’s average for that same month — isolating 10X Genomics Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 60% of the time versus 71% across the last 7 years — the pattern is weakening.
Figures are the typical (median) November return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-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: November, up in 5 of 7 Novembers while the other eleven tend to blur together.
Its average (+16.5%) and median (+12.5%) 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 November ranges by 16.5% 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: November has cleared the S&P 500 by +14.2 points above the index. Some of that is a strong month market-wide, mind — November rises for about 62% of stocks — so the tendency is real if not unique.
A few other months pull their weight: January, June, and July have also closed higher more often than not. The weaker half of the year is plainer: September has been the soft spot — the weakest of 5 months that average a loss (−9.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, February, and March. Its roughest month on record was a −41.1% April 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. With a short 7-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (November, +16.5%) has run well ahead of its worst (September, −9.1%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +16.5% and closing higher in 5 of 7 years since 2019.
It's the weakest, averaging −9.1% — historically a soft spot, though it still varies from year to year.
