Reality check
Over the last 5 years, July has closed higher 100% of the time versus 100% across the last 6 years — the pattern is holding.
Figures are the typical (median) July return and how often it rose — the last 5 years versus the last 6(the heatmap’s default window). This verdict stays anchored to that 6-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 July is the anchor — it has closed higher in all 6 Julys, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+3.7%) and median (+3.1%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: July's returns vary by just 2.4% year to year, and even its worst July in 6 years lost only 0.8% — the gentlest downside anywhere on its calendar. Better still, that strength is the fund's own and not just a buoyant market — July has outpaced the S&P 500 by +1.6 points on average. Few peers keep such company in July — the typical stock clears it just 61% of the time.
July anchors a run, too: the May-through-August window has been the fund's reliable season. On the other side of the ledger, September has been the soft spot — the weakest of 3 months that average a loss (−2.4%), and the edge isn't year-round — the fund has trailed the S&P 500 in April and September.
July has now closed higher 6 years running. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
For a fund this dependable in July, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 6-year record, the signal is best held loosely.
Short answers on the fund's best month (July), its worst (September), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2020 its best month (July, +3.7%) has run well ahead of its worst (September, −2.4%) — the heatmap above shows how steady that gap has been year to year.

It's the weakest, averaging −2.4% — historically a soft spot, though it still varies from year to year.
