Month by month
The fund's clearest edge over the S&P 500 lands in September (+1.5 pts); it has trailed the market most in April (−2.1 pts).
“vs S&P” is Dimensional Global Core Plus Fixed Income ETF’s average for a month minus the S&P 500’s average for that same month — isolating Dimensional Global Core Plus Fixed Income ETF’s own seasonal edge from broad market drift.
Reality check
Over the last 3 years, November has closed higher 100% of the time versus 100% across the last 3 years — the pattern is holding.
Figures are the typical (median) November return and how often it rose — the last 3 years versus the last 3(the heatmap’s default window). This verdict stays anchored to that 3-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Dependability is the through-line here. November stands out, higher in all 3 Novembers, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.5%) and median (+1.8%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
A few other months pull their weight: January, May, and June have also closed higher more often than not. On the other side of the ledger, December is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the fund has trailed the S&P 500 in April, October, and November.
The takeaway is less about when to buy than what to expect: November aside, the fund's months offer little reliable tilt. With a short 3-year record, the signal is best held loosely.
Short answers on the fund's best month (November), its worst (December), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — November is the firmest (+1.5%) and December the softest (+0.5%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
November has been the strongest, averaging +1.5% and closing higher in all 3 years on record since 2023.
It's the weakest month, but it has still averaged a small gain (+0.5%) — quiet rather than genuinely bad.
