Month by month
The fund's clearest edge over the S&P 500 lands in August (+8.6 pts); it has trailed the market most in June (−2.9 pts).
“vs S&P” is Sprott Uranium Miners ETF’s average for a month minus the S&P 500’s average for that same month — isolating Sprott Uranium Miners ETF’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, August has closed higher 80% of the time versus 83% across the last 7 years — the pattern is holding.
Figures are the typical (median) August return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-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 — August. It has closed higher in 5 of 6 Augusts, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+8.9%) and median (+10.3%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: August's returns vary by just 6.0% year to year, and even its worst August in 7 years lost only 2.9% — the gentlest downside anywhere on its calendar. Better still, that strength is the fund's own and not just a buoyant market — August has outpaced the S&P 500 by +8.6 points on average. Few peers keep such company in August — the typical stock clears it just 52% of the time.
August anchors a run, too: the August-through-November window has been the fund's reliable season. At the other end of the calendar, June has been the soft spot — the weakest of 4 months that average a loss (−2.6%), and the edge isn't year-round — the fund has trailed the S&P 500 in June, March, and February. Its roughest month on record was a −17.6% February in 2024 — 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 August, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 7-year record, the signal is best held loosely.
Short answers on the fund's best month (August), its worst (June), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (August, +8.9%) has run well ahead of its worst (June, −2.6%) — the heatmap above shows how steady that gap has been year to year.
August has been the strongest, averaging +8.9% and closing higher in 5 of 6 years since 2019.
It's the weakest, averaging −2.6% — historically a soft spot, though it still varies from year to year.
