Historically, November: over the last 14 years, OSK gained +9.5% on average that month and finished up 92% of the time (13 years observed). September is the weakest month (-3.2%). This is not a prediction: 14 years is a small sample, and the past is under no obligation to repeat.
Why does Oshkosh stock often rise in November?
November has averaged as its best month over 14 years (+9.5%, up 92% of years). No clearly established recurring seasonal driver explains this month — it's a statistical tendency over 14 years of history, not a prediction.
Is there a best month to invest in the stock market in general?
There's no universal rule: every stock has its own seasonality. For OSK it's November (+9.5% on average over 14 years) — another stock will look completely different. The calendar effects people cite ("sell in May", the year-end rally) are market-wide averages, not laws: on OSK, November is the most consistent month (92% positive years). We also rank all 12 months for the whole market.
Does stock seasonality actually work?
Careful. A month that rose 14 times out of 14 can simply be chance: with 12 months and a dozen years, patterns appear naturally even in random data. Seasonality describes what happened; it doesn't explain why and predicts nothing. Treat it as context, never as a standalone buy signal.
