Reality check
Not enough recent July history to say whether the pattern still holds.
Figures are the typical (median) July return and how often it rose — the last 2 years versus the last 2(the heatmap’s default window). This verdict stays anchored to that 2-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: July is nominally the steadiest, yet at 1 of 2 Julys it's barely better than a coin toss.
Its roughest month on record was a −49.0% January in 2025 — a reminder of how hard even a seasonal name can fall.
The honest read is that the calendar is close to noise here — better treated as background than a reason to act. With a short 2-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (July), its worst (January), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2024 its best month (July, +47.2%) has run well ahead of its worst (January, −49.0%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +47.2% and closing higher in 1 of 2 years since 2024.
It's the weakest, averaging −49.0% — historically a soft spot, though it still varies from year to year.
