Reality check
Over the last 5 years, July has closed higher 80% of the time versus 88% across the last 8 years — the pattern is holding.
Figures are the typical (median) July return and how often it rose — the last 5 years versus the last 8(the heatmap’s default window). This verdict stays anchored to that 8-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 7 of 8 Julys, a concentration the rest of the calendar can't touch.
A typical July brings +3.9%, a shade under the +6.2% average. Few months are steadier: July's returns vary by just 7.2% year to year, and even its worst July in 8 years lost only 5.0% — 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 +4.0 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 April-through-August window has been the fund's reliable season. At the other end of the calendar, September has been the soft spot — the weakest of 4 months that average a loss (−1.5%), and the edge isn't year-round — the fund has trailed the S&P 500 in March, April, and December. Its roughest month on record was a −21.6% April in 2022 — 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 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 8-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 2018 its best month (July, +6.2%) has run well ahead of its worst (September, −1.5%) — the heatmap above shows how steady that gap has been year to year.
