Reality check
Over the last 5 years, July has closed higher 100% of the time versus 100% across the last 9 years — the pattern is holding.
Figures are the typical (median) July return and how often it rose — the last 5 years versus the last 9(the heatmap’s default window). This verdict stays anchored to that 9-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. July stands out, higher in all 9 Julys, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.7%) and median (+0.9%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Set against the S&P 500, mind, July is close to a wash — the gain mirrors the market more than it beats it. That consistency sets it apart from the field, where the average stock manages July only about 61% of the time.
The strength clusters rather than stands alone — May–August forms a firm stretch that carries much of the year. On the other side of the ledger, March has been the soft spot — the weakest of 2 months that average a loss (−1.9%), and the edge isn't year-round — the fund has trailed the S&P 500 in March, October, and November. Its roughest month on record was a −12.7% March in 2020 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 9 years running. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
The takeaway is less about when to buy than what to expect: July aside, the fund's months offer little reliable tilt. With a short 9-year record, the signal is best held loosely.
Short answers on the fund's best month (July), its worst (March), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2017 its best month (July, +1.7%) has run well ahead of its worst (March, −1.9%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +1.7% and closing higher in all 9 years on record since 2017.
It's the weakest, averaging −1.9% — historically a soft spot, though it still varies from year to year.
