“vs S&P” is Waystar Holding Corp. Common Stock’s average for a month minus the S&P 500’s average for that same month — isolating Waystar Holding Corp. Common Stock’s own seasonal edge from broad market drift.
Reality check
Not enough recent August history to say whether the pattern still holds.
Figures are the typical (median) August return and how often it rose — the last 2 years versus the last 2(the heatmap’s default window). This verdict stays anchored to that 2-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. August stands out, higher in all 2 Augusts, but it heads a clutch of months that pull the year reliably upward.
Its average (+12.5%) and median (+12.5%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Crucially, the gain is the stock's own rather than a rising tide's: August has cleared the S&P 500 by +12.2 points above the index. That consistency sets it apart from the field, where the average stock manages August only about 52% of the time.
A few other months pull their weight: January, February, and April have also closed higher more often than not. At the other end of the calendar, March has been the soft spot — the only month to average an outright loss (−12.3%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, July, and April. Its roughest month on record was a −12.3% 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: August aside, the stock's months offer little reliable tilt. With a short 2-year record, the signal is best held loosely.
Short answers on the stock's best month (August), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2024 its best month (August, +12.5%) has run well ahead of its worst (March, −12.3%) — the heatmap above shows how steady that gap has been year to year.
August has been the strongest, averaging +12.5% and closing higher in all 2 years on record since 2024.
It's the weakest, averaging −12.3% — historically a soft spot, though it still varies from year to year.
