Month by month
The stock's clearest edge over the S&P 500 lands in June (+1.3 pts); it has trailed the market most in May (−1.3 pts).
“vs S&P” is Johnson & Johnson’s average for a month minus the S&P 500’s average for that same month — isolating Johnson & Johnson’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 60% of the time versus 70% across the last 10 years — the pattern is holding.
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
This is a stock you can almost set a calendar by, and November is the anchor — it has closed higher in 7 of 10 Novembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+2.7%) and median (+4.2%) sit close together, so no single blow-out year is flattering the figure. Set against the S&P 500, mind, November is close to a wash — the gain mirrors the market more than it beats it. 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.
It doesn't stand entirely alone — January, March, and April have leaned firm as well, if less emphatically. The weaker half of the year is plainer: September has been the soft spot — the weakest of 2 months that average a loss (−1.0%), and the edge isn't year-round — the stock has trailed the S&P 500 in May, September, and October. Its roughest month on record was a −11.7% December in 2018 — a reminder of how hard even a seasonal name can fall.
Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
For a stock this dependable in November, 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 (November), its worst (September), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (November, +2.7%) has run well ahead of its worst (September, −1.0%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +2.7% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −1.0% — historically a soft spot, though it still varies from year to year.
