In plain English
Strip the year back and a single month does the heavy lifting: November, up in 4 of 5 Novembers while the other eleven tend to blur together.
Its average (+1.6%) and median (+1.6%) 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, July, and August have also closed higher more often than not. On the other side of the ledger, October has been the soft spot — the weakest of 4 months that average a loss (−1.1%), and the edge isn't year-round — the fund has trailed the S&P 500 in April, October, and March.
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 5-year record, the signal is best held loosely.
Short answers on the fund's best month (November), its worst (October), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — November is the firmest (+1.6%) and October the softest (−1.1%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
November has been the strongest, averaging +1.6% and closing higher in 4 of 5 years since 2021.
It's the weakest, averaging −1.1% — historically a soft spot, though it still varies from year to year.
