Reality check
Over the last 5 years, November has closed higher 80% of the time versus 75% across the last 8 years — the pattern is holding.
Figures are the typical (median) November return and how often it rose — the last 5 years versus the last 8(the heatmap’s default window). This verdict stays anchored to that 8-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 6 of 8 Novembers, a concentration the rest of the calendar can't touch.
A typical November brings +1.7%, a shade under the +3.2% average. Better still, that strength is the fund's own and not just a buoyant market — November has outpaced the S&P 500 by +0.9 points on average. Few peers keep such company in November — the typical stock clears it just 62% of the time.
It doesn't stand entirely alone — March, April, and May have leaned firm as well, if less emphatically. On the other side of the ledger, February has been the soft spot — the weakest of 4 months that average a loss (−1.2%), and the edge isn't year-round — the fund has trailed the S&P 500 in October, March, and February. Its roughest month on record was a −14.5% March in 2020 — a reminder of how hard even a seasonal name can fall.
Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
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 8-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 2018 its best month (November, +3.2%) has run well ahead of its worst (February, −1.2%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +3.2% and closing higher in 6 of 8 years since 2018.
It's the weakest, averaging −1.2% — historically a soft spot, though it still varies from year to year.
