Month by month
The stock's clearest edge over the S&P 500 lands in March (+19.9 pts); it has trailed the market most in September (−12.2 pts).
“vs S&P” is IHS Holding Ltd’s average for a month minus the S&P 500’s average for that same month — isolating IHS Holding Ltd’s own seasonal edge from broad market drift.
Reality check
Over the last 4 years, March has closed higher 75% of the time versus 75% across the last 5 years — the pattern is holding.
Figures are the typical (median) March return and how often it rose — the last 4 years versus the last 5(the heatmap’s default window). This verdict stays anchored to that 5-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 — March. It has closed higher in 3 of 4 Marches, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+20.9%) and median (+20.1%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even March ranges by 16.5% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — March has outpaced the S&P 500 by +19.9 points on average. Few peers keep such company in March — the typical stock clears it just 56% of the time.
It doesn't stand entirely alone — May and November have leaned firm as well, if less emphatically. On the other side of the ledger, September has been the soft spot — the weakest of 7 months that average a loss (−12.3%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, July, and February. Its roughest month on record was a −27.0% September in 2023 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in March, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 5-year record, the signal is best held loosely.
Short answers on the stock's best month (March), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2021 its best month (March, +20.9%) has run well ahead of its worst (September, −12.3%) — the heatmap above shows how steady that gap has been year to year.
March has been the strongest, averaging +20.9% and closing higher in 3 of 4 years since 2021.
It's the weakest, averaging −12.3% — historically a soft spot, though it still varies from year to year.
