Reality check
Over the last 5 years, January has closed higher 80% of the time versus 70% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) January return and how often it rose — the last 5 years versus the last 10(the heatmap’s default window). This verdict stays anchored to that 10-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 — January. It has closed higher in 7 of 10 Januaries, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+4.8%) and median (+6.9%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: January's returns vary by just 9.3% year to year. Better still, that strength is the stock's own and not just a buoyant market — January has outpaced the S&P 500 by +5.0 points on average. Few peers keep such company in January — the typical stock clears it just 53% of the time.
January anchors a run, too: the November-through-January window has been the stock's reliable season. On the other side of the ledger, September has been the soft spot — the weakest of 4 months that average a loss (−1.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, April, and July. Its roughest month on record was a −45.1% March in 2020 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Januaries run ahead of the earlier years.
For a stock this dependable in January, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
Short answers on the stock's best month (January), its worst (September), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (January, +4.8%) has run well ahead of its worst (September, −1.6%) — the heatmap above shows how steady that gap has been year to year.
January has been the strongest, averaging +4.8% and closing higher in 7 of 10 years since 2016.
