Month by month
The stock's clearest edge over the S&P 500 lands in July (+4.1 pts); it has trailed the market most in October (−5.4 pts).
“vs S&P” is JBG SMITH Properties’s average for a month minus the S&P 500’s average for that same month — isolating JBG SMITH Properties’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 100% of the time versus 67% across the last 9 years — the pattern is strengthening.
Figures are the typical (median) July return and how often it rose — the last 5 years versus the last 9(the heatmap’s default window). This verdict stays anchored to that 9-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
There's a real but measured seasonal tilt here, toward July — the firmest corner of the calendar, higher in 6 of 9 Julys.
The strength looks broad-based rather than freakish: its average (+6.2%) and median (+5.0%) sit close together, so no single blow-out year is flattering the figure. Better still, that strength is the stock's own and not just a buoyant market — July has outpaced the S&P 500 by +4.1 points on average. Some of that is a strong month market-wide, mind — July rises for about 61% of stocks — so the tendency is real if not unique.
It doesn't stand entirely alone — May and November have leaned firm as well, if less emphatically. At the other end of the calendar, June is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the stock has trailed the S&P 500 in October, March, and August. Its roughest month on record was a −16.2% March in 2020 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 5 years running. If anything it has sharpened recently — the last five Julys run ahead of the earlier years.
Treat it as a tendency rather than a rule — seasonality describes the past, not a promise. With a short 9-year record, the signal is best held loosely.
Short answers on the stock's best month (July), its worst (June), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2017 its best month (July, +6.2%) has run well ahead of its worst (June, −0.5%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +6.2% and closing higher in 6 of 9 years since 2017.
It's the weakest, averaging −0.5% — historically a soft spot, though it still varies from year to year.
