Month by month
The fund's clearest edge over the S&P 500 lands in September (+13.1 pts); it has trailed the market most in November (−60.7 pts).
“vs S&P” is ProShares Ultra CRCL’s average for a month minus the S&P 500’s average for that same month — isolating ProShares Ultra CRCL’s own seasonal edge from broad market drift.
Reality check
Not enough recent September history to say whether the pattern still holds.
Figures are the typical (median) September return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-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 1 Septembers while the other eleven tend to blur together.
Its average (+13.0%) and median (+13.0%) 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 September in 1 years lost only 13.0% — 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 +13.1 points above the index. It bucks the broad tape, besides: September lifts just 39% of stocks across the market.
Only December comes anywhere near it for reliability. The weaker half of the year is plainer: November has been the soft spot — the weakest of 3 months that average a loss (−58.4%), and the edge isn't year-round — the fund has trailed the S&P 500 in November, August, and October. Its roughest month on record was a −58.4% November in 2025 — 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 1-year record, the signal is best held loosely.
Short answers on the fund's best month (September), its worst (November), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (September, +13.0%) has run well ahead of its worst (November, −58.4%) — the heatmap above shows how steady that gap has been year to year.
September has been the strongest, averaging +13.0% and closing higher in its one year on record since 2025.
It's the weakest, averaging −58.4% — historically a soft spot, though it still varies from year to year.
