Reality check
Over the last 4 years, November has closed higher 100% of the time versus 100% across the last 4 years — the pattern is holding.
Figures are the typical (median) November return and how often it rose — the last 4 years versus the last 4(the heatmap’s default window). This verdict stays anchored to that 4-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 November is the anchor — it has closed higher in all 4 Novembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+2.3%) and median (+2.3%) sit close together, so no single blow-out year is flattering the figure. Set against the S&P 500, mind, November is close to a wash — the gain mirrors the market more than it beats it. 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 July have leaned firm as well, if less emphatically. On the other side of the ledger, February has been the soft spot — the weakest of 3 months that average a loss (−1.0%), and the edge isn't year-round — the fund has trailed the S&P 500 in April, June, and 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 4-year record, the signal is best held loosely.
Short answers on the fund's best month (November), its worst (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2022 its best month (November, +2.3%) has run well ahead of its worst (February, −1.0%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +2.3% and closing higher in all 4 years on record since 2022.
It's the weakest, averaging −1.0% — historically a soft spot, though it still varies from year to year.
