Reality check
Not enough recent May history to say whether the pattern still holds.
Figures are the typical (median) May 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
Strip the year back and a single month does the heavy lifting: May, up in all 1 Mays while the other eleven tend to blur together.
Its average (+81.5%) and median (+81.5%) 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 May in 2 years lost only 81.5% — the gentlest downside anywhere on its calendar. Crucially, the gain is the fund's own rather than a rising tide's: May has cleared the S&P 500 by +80.7 points above the index. That consistency sets it apart from the field, where the average stock manages May only about 55% of the time.
No other month comes close to matching it — the rest of the calendar is unremarkable by comparison. The weaker half of the year is plainer: February has been the soft spot — the weakest of 7 months that average a loss (−35.8%), and the edge isn't year-round — the fund has trailed the S&P 500 in February, March, and April. Its roughest month on record was a −42.3% August in 2024 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: May aside, the fund's months offer little reliable tilt. With a short 2-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the fund's best month (May), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2024 its best month (May, +81.5%) has run well ahead of its worst (February, −35.8%) — the heatmap above shows how steady that gap has been year to year.
May has been the strongest, averaging +81.5% and closing higher in its one year on record since 2024.
It's the weakest, averaging −35.8% — historically a soft spot, though it still varies from year to year.
