Reality check
Not enough recent November history to say whether the pattern still holds.
Figures are the typical (median) November 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
The seasonal story is really one month's story — November. It has closed higher in all 1 Novembers, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+3.7%) and median (+3.7%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: November's returns vary by just 0.0% year to year, and even its worst November in 1 years lost only 3.7% — the gentlest downside anywhere on its calendar. Better still, that strength is the fund's own and not just a buoyant market — November has outpaced the S&P 500 by +1.4 points on average. Few peers keep such company in November — the typical stock clears it just 62% of the time.
Only December comes anywhere near it for reliability. At the other end of the calendar, 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 December.
For a fund 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 1-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.
Yes, to a moderate degree. Since 2025 its best month (November, +3.7%) has run well ahead of its worst (December, +0.5%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +3.7% and closing higher in its one year on record since 2025.
It's the weakest month, but it has still averaged a small gain (+0.5%) — quiet rather than genuinely bad.
