Reality check
Over the last 5 years, June has closed higher 60% of the time versus 70% across the last 10 years — the pattern is holding.
Figures are the typical (median) June return and how often it rose — the last 5 years versus the last 10(the heatmap’s default window). This verdict stays anchored to that 10-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 June is the anchor — it has closed higher in 7 of 10 Junes, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+1.5%) and median (+1.6%) sit close together, so no single blow-out year is flattering the figure. Better still, that strength is the fund's own and not just a buoyant market — June has outpaced the S&P 500 by +1.2 points on average. Few peers keep such company in June — the typical stock clears it just 52% of the time.
June anchors a run, too: the May-through-August window has been the fund's reliable season. The weaker half of the year is plainer: November is the year's low point, though even there the fund has stayed positive on average (+1.8%), a sign every month leans up, and the edge isn't year-round — the fund has trailed the S&P 500 in October, March, and April. Its roughest month on record was a −13.8% 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 June, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
Short answers on the fund's best month (June), its worst (November), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — June is the firmest (+1.5%) and November the softest (+1.8%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
June has been the strongest, averaging +1.5% and closing higher in 7 of 10 years since 2016.
It's the weakest month, but it has still averaged a small gain (+1.8%) — quiet rather than genuinely bad.
