Month by month
The stock's clearest edge over the S&P 500 lands in November (+7.9 pts); it has trailed the market most in March (−12.2 pts).
“vs S&P” is Coastal Financial Corp’s average for a month minus the S&P 500’s average for that same month — isolating Coastal Financial Corp’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 100% of the time versus 88% across the last 8 years — the pattern is weakening.
Figures are the typical (median) November return and how often it rose — the last 5 years versus the last 8(the heatmap’s default window). This verdict stays anchored to that 8-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 November is the anchor — it has closed higher in 7 of 8 Novembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+10.2%) and median (+9.2%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even November ranges by 8.2% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — November has outpaced the S&P 500 by +7.9 points on average. Few peers keep such company in November — the typical stock clears it just 62% of the time.
November anchors a run, too: the October-through-December window has been the stock's reliable season. On the other side of the ledger, March has been the soft spot — the weakest of 2 months that average a loss (−11.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in March and September. Its roughest month on record was a −36.1% March in 2020 — a reminder of how hard even a seasonal name can fall.
November has now closed higher 7 years running. The pattern has softened of late, November's last five years slipping below its longer-run record.
For a stock this dependable in November, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 8-year record, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2018 its best month (November, +10.2%) has run well ahead of its worst (March, −11.2%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +10.2% and closing higher in 7 of 8 years since 2018.
It's the weakest, averaging −11.2% — historically a soft spot, though it still varies from year to year.
