Month by month
The stock's clearest edge over the S&P 500 lands in April (+3.6 pts); it has trailed the market most in March (−9.2 pts).
“vs S&P” is MarineMax Inc’s average for a month minus the S&P 500’s average for that same month — isolating MarineMax Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 40% of the time versus 60% across the last 10 years — the pattern is weakening.
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
No single month dominates — the stock carries a broad upward tilt, with 6 months rising more often than they fall and November (6 of 10 Novembers) nominally in front.
Its average (+4.9%) and median (+6.2%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 9.1% spread), and even its worst November in 10 years lost only 11.6% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: November has cleared the S&P 500 by +2.6 points above the index. Some of that is a strong month market-wide, mind — November rises for about 62% of stocks — so the tendency is real if not unique.
The strength clusters rather than stands alone — October–December forms a firm stretch that carries much of the year. On the other side of the ledger, March has been the soft spot — the weakest of 2 months that average a loss (−8.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, September, and December. Its roughest month on record was a −36.5% March in 2020 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, November's last five years slipping below its longer-run record.
Treat it as a tendency rather than a rule — seasonality describes the past, not a promise. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (November, +4.9%) has run well ahead of its worst (March, −8.1%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +4.9% and closing higher in 6 of 10 years since 2016.
It's the weakest, averaging −8.1% — historically a soft spot, though it still varies from year to year.
