Month by month
The stock's clearest edge over the S&P 500 lands in April (+48.2 pts); it has trailed the market most in July (−5.4 pts).
“vs S&P” is Byrna Technologies Inc’s average for a month minus the S&P 500’s average for that same month — isolating Byrna Technologies Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, April has closed higher 40% of the time versus 60% across the last 10 years — the pattern is weakening.
Figures are the typical (median) April return and how often it rose — the last 5 years versus the last 10(the heatmap’s default window). This verdict stays anchored to that 10-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
April looks the standout, up in 6 of 10 Aprils — yet the appeal is lumpy, leaning on the occasional blow-out year rather than dependable strength.
The headline flatters a touch — its +49.8% average sits well above the +10.2% a typical year delivers, the work of a few big Aprils. That reliability comes with real swings, mind — even April ranges by 133.0% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: April has cleared the S&P 500 by +48.2 points above the index.
Only May comes anywhere near it for reliability. The weaker half of the year is plainer: October is the year's low point, though even there the stock has stayed positive on average (+8.0%), a sign every month leans up, and the edge isn't year-round — the stock has trailed the S&P 500 in July, March, and September. Its roughest month on record was a −45.2% September in 2022 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, April's last five years slipping below its longer-run record.
Hold it loosely, then: the April tendency is genuine but lumpy, more about the occasional outsized year than a gain to bank on. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (April), its worst (October), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (April, +49.8%) has run well ahead of its worst (October, +8.0%) — the heatmap above shows how steady that gap has been year to year.
April has been the strongest, averaging +49.8% and closing higher in 6 of 10 years since 2016.
It's the weakest month, but it has still averaged a small gain (+8.0%) — quiet rather than genuinely bad.
