Month by month
Across the year the fund has stayed close to the S&P 500 — no single month stands out as a real edge.
“vs S&P” is WEEK’s average for a month minus the S&P 500’s average for that same month — isolating WEEK’s own seasonal edge from broad market drift.
Reality check
Not enough recent December history to say whether the pattern still holds.
Figures are the typical (median) December return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
This is a fund you can almost set a calendar by, and December is the anchor — it has closed higher in all 1 Decembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+0.4%) and median (+0.4%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: December's returns vary by just 0.0% year to year, and even its worst December in 1 years lost only 0.4% — the gentlest downside anywhere on its calendar. Few peers keep such company in December — the typical stock clears it just 58% of the time.
The lift is near-universal — strength runs through almost every month of the year, not one window. The weaker half of the year is plainer: November 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 November, July, and April.
For a fund this dependable in December, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 1-year record, the signal is best held loosely.
Short answers on the fund's best month (December), its worst (November), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — December is the firmest (+0.4%) and November the softest (+0.3%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
December has been the strongest, averaging +0.4% and closing higher in its one year on record since 2025.
It's the weakest month, but it has still averaged a small gain (+0.3%) — quiet rather than genuinely bad.
