Month by month
The stock's clearest edge over the S&P 500 lands in June (+14.6 pts); it has trailed the market most in May (−19.5 pts).
“vs S&P” is ChronoScale Corporation’s average for a month minus the S&P 500’s average for that same month — isolating ChronoScale Corporation’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, September has closed higher 40% of the time versus 50% across the last 10 years — the pattern is weakening.
Figures are the typical (median) September 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 little seasonal signal to find. No month pulls clear: September is nominally the steadiest, yet at 5 of 10 Septembers it's barely better than a coin toss.
Its roughest month on record was a −63.8% May in 2017 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, September's last five years slipping below its longer-run record.
The honest read is that the calendar is close to noise here — better treated as background than a reason to act. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (September), its worst (May), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (September, −1.7%) has run well ahead of its worst (May, −18.8%) — the heatmap above shows how steady that gap has been year to year.
September has been the strongest, averaging −1.7% and closing higher in 5 of 10 years since 2016.
It's the weakest, averaging −18.8% — historically a soft spot, though it still varies from year to year.
