Month by month
The stock's clearest edge over the S&P 500 lands in August (+13.5 pts); it has trailed the market most in November (−5.5 pts).
“vs S&P” is GPGI, Inc.’s average for a month minus the S&P 500’s average for that same month — isolating GPGI, Inc.’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, April has closed higher 80% of the time versus 80% across the last 6 years — the pattern is holding.
Figures are the typical (median) April 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: April, up in 4 of 5 Aprils while the other eleven tend to blur together.
Its average (+0.9%) and median (+0.9%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 2.0% spread). That consistency sets it apart from the field, where the average stock manages April only about 55% of the time.
A few other months pull their weight: January, March, and June 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 (−3.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in November, December, and June. Its roughest month on record was a −31.8% June 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: April 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 (April), its worst (December), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2020 its best month (April, +0.9%) has run well ahead of its worst (December, −3.5%) — the heatmap above shows how steady that gap has been year to year.
April has been the strongest, averaging +0.9% and closing higher in 4 of 5 years since 2020.
It's the weakest, averaging −3.5% — historically a soft spot, though it still varies from year to year.
