Month by month
The stock's clearest edge over the S&P 500 lands in April (+1.6 pts); it has trailed the market most in October (−3.1 pts).
“vs S&P” is Diageo PLC ADR’s average for a month minus the S&P 500’s average for that same month — isolating Diageo 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 80% across the last 10 years — the pattern is weakening.
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
The seasonal story is really one month's story — April. It has closed higher in 8 of 10 Aprils, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+3.3%) and median (+2.7%) sit close together, so no single blow-out year is flattering the figure. Better still, that strength is the stock's own and not just a buoyant market — April has outpaced the S&P 500 by +1.6 points on average. Few peers keep such company in April — the typical stock clears it just 55% of the time.
It doesn't stand entirely alone — March, July, and November have leaned firm as well, if less emphatically. At the other end of the calendar, February has been the soft spot — the weakest of 4 months that average a loss (−2.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, June, and February. Its roughest month on record was a −13.8% September in 2025 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, April's last five years slipping below its longer-run record.
For a stock this dependable in April, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
Short answers on the stock's best month (April), its worst (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (April, +3.3%) has run well ahead of its worst (February, −2.4%) — the heatmap above shows how steady that gap has been year to year.
April has been the strongest, averaging +3.3% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −2.4% — historically a soft spot, though it still varies from year to year.
