Month by month
The stock's clearest edge over the S&P 500 lands in November (+12.0 pts); it has trailed the market most in March (−12.7 pts).
“vs S&P” is Snowflake Inc.’s average for a month minus the S&P 500’s average for that same month — isolating Snowflake Inc.’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 80% of the time versus 80% across the last 6 years — the pattern is holding.
Figures are the typical (median) June return and how often it rose — the last 5 years versus the last 6(the heatmap’s default window). This verdict stays anchored to that 6-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Strip the year back and a single month does the heavy lifting: June, up in 4 of 5 Junes while the other eleven tend to blur together.
Its average (+4.2%) and median (+5.2%) 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 4.2% spread), and even its worst June in 6 years lost only 1.3% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: June has cleared the S&P 500 by +4.0 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
The strength clusters rather than stands alone — May–August 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 5 months that average a loss (−11.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, April, and February. Its roughest month on record was a −28.2% May in 2022 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: June aside, the stock's months offer little reliable tilt. With a short 6-year record, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2020 its best month (June, +4.2%) has run well ahead of its worst (March, −11.6%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +4.2% and closing higher in 4 of 5 years since 2020.
It's the weakest, averaging −11.6% — historically a soft spot, though it still varies from year to year.
