Month by month
The fund's clearest edge over the S&P 500 lands in January (+0.8 pts); it has trailed the market most in November (−1.9 pts).
“vs S&P” is Invesco Senior Loan ETF’s average for a month minus the S&P 500’s average for that same month — isolating Invesco Senior Loan ETF’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, April has closed higher 80% of the time versus 90% across the last 10 years — the pattern is holding.
Figures are the typical (median) April return and how often it rose — the last 5 years versus the last 10(the heatmap’s default window). This verdict stays anchored to that 10-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. April stands out, higher in 9 of 10 Aprils, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.1%) and median (+0.5%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That consistency sets it apart from the field, where the average stock manages April only about 55% of the time.
A few other months pull their weight: May, July, and August have also closed higher more often than not. On the other side of the ledger, March 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 November, March, and July.
Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
The takeaway is less about when to buy than what to expect: April aside, the fund's months offer little reliable tilt.
Short answers on the fund's best month (April), its worst (March), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — April is the firmest (+1.1%) and March the softest (−0.4%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
April has been the strongest, averaging +1.1% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −0.4% — historically a soft spot, though it still varies from year to year.
