Month by month
The stock's clearest edge over the S&P 500 lands in November (+4.3 pts); it has trailed the market most in March (−4.6 pts).
“vs S&P” is Janus Henderson Group PLC’s average for a month minus the S&P 500’s average for that same month — isolating Janus Henderson Group PLC’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 100% of the time versus 89% across the last 9 years — the pattern is strengthening.
Figures are the typical (median) July return and how often it rose — the last 5 years versus the last 9(the heatmap’s default window). This verdict stays anchored to that 9-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. July stands out, higher in 8 of 9 Julys, but it heads a clutch of months that pull the year reliably upward.
Its average (+5.5%) and median (+7.0%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 5.2% spread), and even its worst July in 9 years lost only 7.2% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: July has cleared the S&P 500 by +3.3 points above the index. That consistency sets it apart from the field, where the average stock manages July only about 61% of the time.
A few other months pull their weight: January, May, and August have also closed higher more often than not. The weaker half of the year is plainer: April is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the stock has trailed the S&P 500 in March, February, and April. Its roughest month on record was a −29.3% March in 2020 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 6 years running. If anything it has sharpened recently — the last five Julys run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: July aside, the stock's months offer little reliable tilt. With a short 9-year record, the signal is best held loosely.
Short answers on the stock's best month (July), its worst (April), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2017 its best month (July, +5.5%) has run well ahead of its worst (April, +0.1%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +5.5% and closing higher in 8 of 9 years since 2017.
It's the weakest month, but it has still averaged a small gain (+0.1%) — quiet rather than genuinely bad.
