Reality check
Over the last 5 years, November has closed higher 80% of the time versus 60% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) November 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 year leans November's way without overwhelming the rest of it: the stock has closed higher in 6 of 10 Novembers, its most dependable month if not a dominant one.
A typical November brings +3.4%, a shade under the +4.8% average. That reliability comes with real swings, mind — even November ranges by 8.8% 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: November has cleared the S&P 500 by +2.5 points above the index. Some of that is a strong month market-wide, mind — November rises for about 62% of stocks — so the tendency is real if not unique.
A few other months pull their weight: January, April, and July have also closed higher more often than not. On the other side of the ledger, October has been the soft spot — the weakest of 7 months that average a loss (−2.3%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, May, and June. Its roughest month on record was a −23.4% March in 2020 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Novembers run ahead of the earlier years.
Treat it as a tendency rather than a rule — seasonality describes the past, not a promise.
