Over 2013-2026, July is Polaris's strongest month: +7.5% on average, positive in 9 of 14 years. At the other end, December shows -4.4%. But a monthly gap is often built on one or two extreme years — the table above shows it: look at the spread, not just the average. Seasonality only means something when it has a cause (selling season, earnings calendar, year-end tax effects); with no identified cause, it's probably noise.

Historically, July: over the last 14 years, PII gained +7.5% on average that month and finished up 64% of the time (14 years observed). December is the weakest month (-4.4%). This is not a prediction: 14 years is a small sample, and the past is under no obligation to repeat.
Why does Polaris stock often rise in July?
July has averaged as its best month over 14 years (+7.5%, up 64% 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 PII it's July (+7.5% 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 PII, February is the most consistent month (71% 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.
