Reality check
Not enough recent September history to say whether the pattern still holds.
Figures are the typical (median) September 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
Strip the year back and a single month does the heavy lifting: September, up in all 1 Septembers while the other eleven tend to blur together.
Its average (+64.8%) and median (+64.8%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 0.0% spread), and even its worst September in 1 years lost only 64.8% — the gentlest downside anywhere on its calendar. Crucially, the gain is the fund's own rather than a rising tide's: September has cleared the S&P 500 by +64.9 points above the index. It bucks the broad tape, besides: September lifts just 39% of stocks across the market.
A few other months pull their weight: June, July, and October have also closed higher more often than not. The weaker half of the year is plainer: August has been the soft spot — the weakest of 6 months that average a loss (−34.1%), and the edge isn't year-round — the fund has trailed the S&P 500 in August, March, and April. Its roughest month on record was a −34.1% August in 2025 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: September aside, the fund's months offer little reliable tilt. With a short 1-year record, the signal is best held loosely.
Short answers on the fund's best month (September), its worst (August), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (September, +64.8%) has run well ahead of its worst (August, −34.1%) — the heatmap above shows how steady that gap has been year to year.
September has been the strongest, averaging +64.8% and closing higher in its one year on record since 2025.
It's the weakest, averaging −34.1% — historically a soft spot, though it still varies from year to year.
