Month by month
The stock's clearest edge over the S&P 500 lands in April (+9.7 pts); it has trailed the market most in February (−5.7 pts).
“vs S&P” is Euroseas Ltd’s average for a month minus the S&P 500’s average for that same month — isolating Euroseas Ltd’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, March has closed higher 60% of the time versus 70% across the last 10 years — the pattern is weakening.
Figures are the typical (median) March 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
This is a stock you can almost set a calendar by, and March is the anchor — it has closed higher in 7 of 10 Marches, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+5.7%) and median (+4.2%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: March's returns vary by just 12.9% year to year, and even its worst March in 10 years lost only 13.8% — the gentlest downside anywhere on its calendar. Better still, that strength is the stock's own and not just a buoyant market — March has outpaced the S&P 500 by +4.7 points on average. Few peers keep such company in March — the typical stock clears it just 56% of the time.
It doesn't stand entirely alone — January, April, and July have leaned firm as well, if less emphatically. The weaker half of the year is plainer: February has been the soft spot — the weakest of 3 months that average a loss (−6.0%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, October, and December. Its roughest month on record was a −50.0% November in 2018 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, March's last five years slipping below its longer-run record.
For a stock this dependable in March, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (March), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (March, +5.7%) has run well ahead of its worst (February, −6.0%) — the heatmap above shows how steady that gap has been year to year.
March has been the strongest, averaging +5.7% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −6.0% — historically a soft spot, though it still varies from year to year.
