Month by month
The stock's clearest edge over the S&P 500 lands in May (+16.6 pts); it has trailed the market most in October (−14.2 pts).
“vs S&P” is SharkNinja, Inc.’s average for a month minus the S&P 500’s average for that same month — isolating SharkNinja, Inc.’s own seasonal edge from broad market drift.
Reality check
Not enough recent May history to say whether the pattern still holds.
Figures are the typical (median) May return and how often it rose — the last 2 years versus the last 3(the heatmap’s default window). This verdict stays anchored to that 3-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Dependability is the through-line here. May stands out, higher in all 2 Mays, but it heads a clutch of months that pull the year reliably upward.
Its average (+17.3%) and median (+17.3%) 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 2.2% spread), and even its worst May in 3 years lost only 15.2% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: May has cleared the S&P 500 by +16.6 points above the index. That consistency sets it apart from the field, where the average stock manages May only about 55% of the time.
A few other months pull their weight: August, September, and November have also closed higher more often than not. The weaker half of the year is plainer: October has been the soft spot — the weakest of 2 months that average a loss (−13.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, March, and April. Its roughest month on record was a −16.0% March in 2025 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: May aside, the stock's months offer little reliable tilt. With a short 3-year record, the signal is best held loosely.
Short answers on the stock's best month (May), its worst (October), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2023 its best month (May, +17.3%) has run well ahead of its worst (October, −13.2%) — the heatmap above shows how steady that gap has been year to year.
May has been the strongest, averaging +17.3% and closing higher in all 2 years on record since 2023.
It's the weakest, averaging −13.2% — historically a soft spot, though it still varies from year to year.
