Reality check
Over the last 5 years, January has closed higher 100% of the time versus 80% 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
Dependability is the through-line here. January stands out, higher in 8 of 10 Januaries, but it heads a clutch of months that pull the year reliably upward.
Its average (+0.4%) and median (+4.0%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That reliability comes with real swings, mind — even January ranges by 11.3% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: January has cleared the S&P 500 by +0.6 points above the index. That consistency sets it apart from the field, where the average stock manages January only about 53% of the time.
A few other months pull their weight: February, April, and May have also closed higher more often than not. At the other end of the calendar, August has been the soft spot — the weakest of 2 months that average a loss (−2.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, August, and July. Its roughest month on record was a −76.4% March in 2020 — a reminder of how hard even a seasonal name can fall.
January has now closed higher 5 years running. If anything it has sharpened recently — the last five Januaries run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: January aside, the stock's months offer little reliable tilt. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (January), its worst (August), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — January is the firmest (+0.4%) and August the softest (−2.1%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
January has been the strongest, averaging +0.4% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −2.1% — historically a soft spot, though it still varies from year to year.
