Month by month
The stock's clearest edge over the S&P 500 lands in November (+4.0 pts); it has trailed the market most in October (−2.5 pts).
“vs S&P” is AbbVie Inc’s average for a month minus the S&P 500’s average for that same month — isolating AbbVie Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 60% of the time versus 80% across the last 10 years — the pattern is weakening.
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 8 of 10 Novembers while the other eleven tend to blur together.
Its average (+6.3%) and median (+7.4%) 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 +4.0 points above the index. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
A few other months pull their weight: February, March, and June have also closed higher more often than not. On the other side of the ledger, May has been the soft spot — the weakest of 4 months that average a loss (−0.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, March, and May. Its roughest month on record was a −17.2% October in 2018 — a reminder of how hard even a seasonal name can fall.
At its steadiest, November strung together 7 straight positive years. The pattern has softened of late, November's last five years slipping below its longer-run record.
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 (May), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (November, +6.3%) has run well ahead of its worst (May, −0.8%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +6.3% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −0.8% — historically a soft spot, though it still varies from year to year.
