Month by month
The stock's clearest edge over the S&P 500 lands in July (+4.6 pts); it has trailed the market most in December (−6.5 pts).
“vs S&P” is Polaris Industries Inc’s average for a month minus the S&P 500’s average for that same month — isolating Polaris Industries Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 80% of the time versus 70% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) July 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
The seasonal story is really one month's story — July. It has closed higher in 7 of 10 Julys, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+6.8%) and median (+10.9%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even July ranges by 10.1% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — July has outpaced the S&P 500 by +4.6 points on average. Some of that is a strong month market-wide, mind — July rises for about 61% of stocks — so the tendency is real if not unique.
It doesn't stand entirely alone — February, June, and November have leaned firm as well, if less emphatically. At the other end of the calendar, December has been the soft spot — the weakest of 6 months that average a loss (−5.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in December, March, and October. Its roughest month on record was a −43.4% March in 2020 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Julys run ahead of the earlier years.
For a stock this dependable in July, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
