Reality check
Over the last 3 years, December has closed higher 100% of the time versus 100% across the last 3 years — the pattern is holding.
Figures are the typical (median) December return and how often it rose — the last 3 years versus the last 3(the heatmap’s default window). This verdict stays anchored to that 3-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 December is the anchor — it has closed higher in all 3 Decembers, the steadiest beat on its year.
Read it with one caveat: the average (+28.3%) runs well ahead of the median (+0.5%), so a handful of outsized years — not steady strength — do much of the lifting. That reliability comes with real swings, mind — even December ranges by 39.5% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — December has outpaced the S&P 500 by +27.3 points on average. Few peers keep such company in December — the typical stock clears it just 58% of the time.
The lift is near-universal — strength runs through almost every month of the year, not one window. On the other side of the ledger, September has been the soft spot — the weakest of 2 months that average a loss (−13.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, November, and July. Its roughest month on record was a −40.1% September in 2025 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in December, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 3-year record, the signal is best held loosely.
Short answers on the stock's best month (December), its worst (September), and whether it really trades seasonally.
