Reality check
Not enough recent June history to say whether the pattern still holds.
Figures are the typical (median) June return and how often it rose — the last 1 years versus the last 2(the heatmap’s default window). This verdict stays anchored to that 2-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Dependability is the through-line here. June stands out, higher in all 1 Junes, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.4%) and median (+1.4%) 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 June in 2 years lost only 1.4% — the gentlest downside anywhere on its calendar. Crucially, the gain is the fund's own rather than a rising tide's: June has cleared the S&P 500 by +1.1 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
A few other months pull their weight: January, February, and May have also closed higher more often than not. At the other end of the calendar, March has been the soft spot — the weakest of 2 months that average a loss (−1.2%), and the edge isn't year-round — the fund has trailed the S&P 500 in April, March, and July.
The takeaway is less about when to buy than what to expect: June aside, the fund's months offer little reliable tilt. With a short 2-year record, the signal is best held loosely.
Short answers on the fund's best month (June), its worst (March), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — June is the firmest (+1.4%) and March the softest (−1.2%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
June has been the strongest, averaging +1.4% and closing higher in its one year on record since 2024.
It's the weakest, averaging −1.2% — historically a soft spot, though it still varies from year to year.
