Reality check
Not enough recent October history to say whether the pattern still holds.
Figures are the typical (median) October return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
This is a stock you can almost set a calendar by, and October is the anchor — it has closed higher in all 1 Octobers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+34.3%) and median (+34.3%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: October's returns vary by just 0.0% year to year, and even its worst October in 1 years lost only 34.3% — the gentlest downside anywhere on its calendar. Better still, that strength is the stock's own and not just a buoyant market — October has outpaced the S&P 500 by +33.3 points on average. Few peers keep such company in October — the typical stock clears it just 53% of the time.
It doesn't stand entirely alone — June, July, and December have leaned firm as well, if less emphatically. On the other side of the ledger, August has been the soft spot — the weakest of 3 months that average a loss (−25.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in August, November, and September. Its roughest month on record was a −25.8% August in 2025 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in October, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 1-year record, the signal is best held loosely.
Short answers on the stock's best month (October), its worst (August), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (October, +34.3%) has run well ahead of its worst (August, −25.8%) — the heatmap above shows how steady that gap has been year to year.
