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 (+1.2%) and median (+1.2%) 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 1.2% — the gentlest downside anywhere on its calendar. Set against the S&P 500, mind, October is close to a wash — the gain mirrors the market more than it beats it. Few peers keep such company in October — the typical stock clears it just 53% of the time.
It doesn't stand entirely alone — February, March, and April have leaned firm as well, if less emphatically. At the other end of the calendar, November 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 November, July, and April.
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 (November), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — October is the firmest (+1.2%) and November the softest (−0.4%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
October has been the strongest, averaging +1.2% and closing higher in its one year on record since 2025.
It's the weakest, averaging −0.4% — historically a soft spot, though it still varies from year to year.
