Month by month
The stock's clearest edge over the S&P 500 lands in January (+3.8 pts); it has trailed the market most in December (−3.0 pts).
“vs S&P” is Ball Corporation’s average for a month minus the S&P 500’s average for that same month — isolating Ball Corporation’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 100% of the time versus 70% 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
Strip the year back and a single month does the heavy lifting: November, up in 7 of 10 Novembers while the other eleven tend to blur together.
Its average (+4.0%) and median (+4.2%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Crucially, the gain is the stock's own rather than a rising tide's: November has cleared the S&P 500 by +1.7 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, March, and April have also closed higher more often than not. At the other end of the calendar, February has been the soft spot — the weakest of 5 months that average a loss (−1.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in December, October, and September. Its roughest month on record was a −23.4% August in 2022 — a reminder of how hard even a seasonal name can fall.
November has now closed higher 6 years running. If anything it has sharpened recently — the last five Novembers run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: November aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (November), its worst (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (November, +4.0%) has run well ahead of its worst (February, −1.2%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +4.0% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −1.2% — historically a soft spot, though it still varies from year to year.
