Month by month
The fund's clearest edge over the S&P 500 lands in September (+22.3 pts); it has trailed the market most in February (−16.8 pts).
“vs S&P” is Sprott Junior Uranium Miners ETF’s average for a month minus the S&P 500’s average for that same month — isolating Sprott Junior Uranium Miners ETF’s own seasonal edge from broad market drift.
Reality check
Over the last 3 years, September has closed higher 100% of the time versus 100% across the last 3 years — the pattern is holding.
Figures are the typical (median) September return and how often it rose — the last 3 years versus the last 3(the heatmap’s default window). This verdict stays anchored to that 3-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: September, up in all 3 Septembers while the other eleven tend to blur together.
Its average (+22.1%) and median (+21.5%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 1.6% spread), and even its worst September in 3 years lost only 20.6% — the gentlest downside anywhere on its calendar. Crucially, the gain is the fund's own rather than a rising tide's: September has cleared the S&P 500 by +22.3 points above the index. It bucks the broad tape, besides: September lifts just 39% of stocks across the market.
The strength clusters rather than stands alone — August–November forms a firm stretch that carries much of the year. On the other side of the ledger, February has been the soft spot — the weakest of 4 months that average a loss (−17.0%), and the edge isn't year-round — the fund has trailed the S&P 500 in February, March, and July. Its roughest month on record was a −18.6% February 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: September aside, the fund's months offer little reliable tilt. With a short 3-year record, the signal is best held loosely.
Short answers on the fund's best month (September), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2023 its best month (September, +22.1%) has run well ahead of its worst (February, −17.0%) — the heatmap above shows how steady that gap has been year to year.
September has been the strongest, averaging +22.1% and closing higher in all 3 years on record since 2023.
It's the weakest, averaging −17.0% — historically a soft spot, though it still varies from year to year.
