Month by month
The stock's clearest edge over the S&P 500 lands in August (+5.7 pts); it has trailed the market most in February (−7.1 pts).
“vs S&P” is Arko Corp’s average for a month minus the S&P 500’s average for that same month — isolating Arko Corp’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 60% of the time versus 71% across the last 9 years — the pattern is weakening.
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
Strip the year back and a single month does the heavy lifting: June, up in 5 of 7 Junes while the other eleven tend to blur together.
Its average (+0.3%) and median (+2.1%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Set against the S&P 500, mind, June is close to a wash — the gain mirrors the market more than it beats it. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
A few other months pull their weight: January, March, and August have also closed higher more often than not. The weaker half of the year is plainer: December has been the soft spot — the weakest of 4 months that average a loss (−2.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, April, and December. Its roughest month on record was a −35.5% February in 2025 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, June's last five years slipping below its longer-run record.
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 9-year record, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (December), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2017 its best month (June, +0.3%) has run well ahead of its worst (December, −2.8%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +0.3% and closing higher in 5 of 7 years since 2017.
It's the weakest, averaging −2.8% — historically a soft spot, though it still varies from year to year.
