Month by month
The stock's clearest edge over the S&P 500 lands in April (+4.2 pts); it has trailed the market most in March (−5.8 pts).
“vs S&P” is WPP PLC ADR’s average for a month minus the S&P 500’s average for that same month — isolating WPP PLC ADR’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, April has closed higher 60% of the time versus 70% 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
Strip the year back and a single month does the heavy lifting: April, up in 7 of 10 Aprils while the other eleven tend to blur together.
Its average (+5.9%) and median (+5.2%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That reliability comes with real swings, mind — even April ranges by 9.5% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: April has cleared the S&P 500 by +4.2 points above the index. 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: August, October, and November have also closed higher more often than not. At the other end of the calendar, June has been the soft spot — the weakest of 8 months that average a loss (−3.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, July, and February. Its roughest month on record was a −29.2% March in 2020 — 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.
The takeaway is less about when to buy than what to expect: April aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (April), its worst (June), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (April, +5.9%) has run well ahead of its worst (June, −3.5%) — the heatmap above shows how steady that gap has been year to year.
April has been the strongest, averaging +5.9% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −3.5% — historically a soft spot, though it still varies from year to year.
