Reality check
Not enough recent February history to say whether the pattern still holds.
Figures are the typical (median) February return and how often it rose — the last 1 years versus the last 2(the heatmap’s default window). This verdict stays anchored to that 2-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. February stands out, higher in all 1 Februaries, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.2%) and median (+1.2%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 0.0% spread), and even its worst February in 2 years lost only 1.2% — the gentlest downside anywhere on its calendar. Crucially, the gain is the fund's own rather than a rising tide's: February has cleared the S&P 500 by +1.5 points above the index. It bucks the broad tape, besides: February lifts just 49% of stocks across the market.
The strength clusters rather than stands alone — January–August forms a firm stretch that carries much of the year. On the other side of the ledger, October is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the fund has trailed the S&P 500 in July, November, and October.
The takeaway is less about when to buy than what to expect: February aside, the fund's months offer little reliable tilt. With a short 2-year record, the signal is best held loosely.
Short answers on the fund's best month (February), its worst (October), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — February is the firmest (+1.2%) and October the softest (−0.5%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
February has been the strongest, averaging +1.2% and closing higher in its one year on record since 2024.
It's the weakest, averaging −0.5% — historically a soft spot, though it still varies from year to year.
