Reality check
Over the last 5 years, July has closed higher 100% of the time versus 100% across the last 10 years — the pattern is holding.
Figures are the typical (median) July 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
The seasonal story is really one month's story — July. It has closed higher in all 10 Julys, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+1.7%) and median (+1.5%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: July's returns vary by just 1.1% year to year, and even its worst July in 10 years lost only 0.2% — the gentlest downside anywhere on its calendar. Set against the S&P 500, mind, July is close to a wash — the gain mirrors the market more than it beats it. 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, February 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 March, April, and October. Its roughest month on record was a −15.7% March in 2020 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 10 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.
Short answers on the fund's best month (July), its worst (February), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — July is the firmest (+1.7%) and February the softest (−1.1%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
July has been the strongest, averaging +1.7% and closing higher in all 10 years on record since 2016.
It's the weakest, averaging −1.1% — historically a soft spot, though it still varies from year to year.
