“vs S&P” is Eastern Bankshares Inc’s average for a month minus the S&P 500’s average for that same month — isolating Eastern Bankshares Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 80% of the time versus 83% across the last 6 years — the pattern is holding.
Figures are the typical (median) November 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
This is a stock you can almost set a calendar by, and November is the anchor — it has closed higher in 5 of 6 Novembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+9.4%) and median (+9.3%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even November ranges by 8.7% 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 +7.0 points on average. Few peers keep such company in November — the typical stock clears it just 62% of the time.
It doesn't stand entirely alone — January, March, and May have leaned firm as well, if less emphatically. The weaker half of the year is plainer: April has been the soft spot — the weakest of 3 months that average a loss (−5.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, October, and March. Its roughest month on record was a −18.7% March in 2023 — a reminder of how hard even a seasonal name can fall.
Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
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 6-year record, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (April), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2020 its best month (November, +9.4%) has run well ahead of its worst (April, −5.2%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +9.4% and closing higher in 5 of 6 years since 2020.
It's the weakest, averaging −5.2% — historically a soft spot, though it still varies from year to year.
