Month by month
The stock's clearest edge over the S&P 500 lands in November (+6.1 pts); it has trailed the market most in February (−3.1 pts).
“vs S&P” is Oshkosh Corporation’s average for a month minus the S&P 500’s average for that same month — isolating Oshkosh Corporation’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 80% of the time versus 90% 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
Strip the year back and a single month does the heavy lifting: November, up in 9 of 10 Novembers while the other eleven tend to blur together.
A typical November brings +5.6%, a shade under the +8.5% average. That reliability comes with real swings, mind — even November ranges by 8.1% 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 +6.1 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: January and July have also closed higher more often than not. On the other side of the ledger, February has been the soft spot — the weakest of 4 months that average a loss (−3.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, December, and March. Its roughest month on record was a −21.0% October 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.
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 pronounced degree. Since 2016 its best month (November, +8.5%) has run well ahead of its worst (February, −3.4%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +8.5% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −3.4% — historically a soft spot, though it still varies from year to year.
