Month by month
The stock's clearest edge over the S&P 500 lands in January (+4.5 pts); it has trailed the market most in September (−2.3 pts).
“vs S&P” is Corteva Inc’s average for a month minus the S&P 500’s average for that same month — isolating Corteva Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, January has closed higher 80% of the time versus 83% across the last 7 years — the pattern is holding.
Figures are the typical (median) January return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-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 January is the anchor — it has closed higher in 5 of 6 Januaries, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+4.3%) and median (+3.2%) sit close together, so no single blow-out year is flattering the figure. Better still, that strength is the stock's own and not just a buoyant market — January has outpaced the S&P 500 by +4.5 points on average. Few peers keep such company in January — the typical stock clears it just 53% of the time.
January anchors a run, too: the November-through-January window has been the stock's reliable season. On the other side of the ledger, September has been the soft spot — the only month to average an outright loss (−2.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in September and July. Its roughest month on record was a −16.8% March in 2020 — 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 January, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 7-year record, the signal is best held loosely.
Short answers on the stock's best month (January), its worst (September), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2019 its best month (January, +4.3%) has run well ahead of its worst (September, −2.4%) — the heatmap above shows how steady that gap has been year to year.
January has been the strongest, averaging +4.3% and closing higher in 5 of 6 years since 2019.
It's the weakest, averaging −2.4% — historically a soft spot, though it still varies from year to year.
