Month by month
The stock's clearest edge over the S&P 500 lands in June (+7.4 pts); it has trailed the market most in July (−7.9 pts).
“vs S&P” is Snap Inc’s average for a month minus the S&P 500’s average for that same month — isolating Snap 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 78% across the last 9 years — the pattern is holding.
Figures are the typical (median) June return and how often it rose — the last 5 years versus the last 9(the heatmap’s default window). This verdict stays anchored to that 9-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 — June. It has closed higher in 7 of 9 Junes, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+7.6%) and median (+8.4%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: June's returns vary by just 11.7% year to year. Better still, that strength is the stock's own and not just a buoyant market — June has outpaced the S&P 500 by +7.4 points on average. Few peers keep such company in June — the typical stock clears it just 52% of the time.
Only January comes anywhere near it for reliability. At the other end of the calendar, July has been the soft spot — the weakest of 5 months that average a loss (−5.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in July, March, and May. Its roughest month on record was a −52.2% May in 2022 — a reminder of how hard even a seasonal name can fall.
Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
For a stock this dependable in June, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 9-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (July), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2017 its best month (June, +7.6%) has run well ahead of its worst (July, −5.8%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +7.6% and closing higher in 7 of 9 years since 2017.
It's the weakest, averaging −5.8% — historically a soft spot, though it still varies from year to year.
