Reality check
Not enough recent May history to say whether the pattern still holds.
Figures are the typical (median) May 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
The seasonal story is really one month's story — May. It has closed higher in all 1 Mays, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+151.2%) and median (+151.2%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: May's returns vary by just 0.0% year to year, and even its worst May in 1 years lost only 151.2% — the gentlest downside anywhere on its calendar. Better still, that strength is the stock's own and not just a buoyant market — May has outpaced the S&P 500 by +150.4 points on average. Few peers keep such company in May — the typical stock clears it just 55% of the time.
It doesn't stand entirely alone — June and September have leaned firm as well, if less emphatically. At the other end of the calendar, November has been the soft spot — the weakest of 7 months that average a loss (−42.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in November, July, and April. Its roughest month on record was a −42.1% November in 2025 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in May, 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 (May), its worst (November), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (May, +151.2%) has run well ahead of its worst (November, −42.1%) — the heatmap above shows how steady that gap has been year to year.
May has been the strongest, averaging +151.2% and closing higher in its one year on record since 2025.
It's the weakest, averaging −42.1% — historically a soft spot, though it still varies from year to year.
