Month by month
The stock's clearest edge over the S&P 500 lands in November (+2.0 pts); it has trailed the market most in October (−2.5 pts).
“vs S&P” is Vodafone Group PLC ADR’s average for a month minus the S&P 500’s average for that same month — isolating Vodafone Group PLC ADR’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, January has closed higher 80% of the time versus 70% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) January 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: January, up in 7 of 10 Januaries while the other eleven tend to blur together.
The headline flatters a touch — its +1.7% average sits well above the +0.2% a typical year delivers, the work of a few big Januaries. Crucially, the gain is the stock's own rather than a rising tide's: January has cleared the S&P 500 by +1.9 points above the index. That consistency sets it apart from the field, where the average stock manages January only about 53% of the time.
A few other months pull their weight: April, May, and July have also closed higher more often than not. At the other end of the calendar, June has been the soft spot — the weakest of 7 months that average a loss (−0.9%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, September, and March. Its roughest month on record was a −20.7% March in 2020 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Januaries run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: January aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (January), its worst (June), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — January is the firmest (+1.7%) and June the softest (−0.9%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
January has been the strongest, averaging +1.7% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −0.9% — historically a soft spot, though it still varies from year to year.
