Month by month
The stock's clearest edge over the S&P 500 lands in January (+3.5 pts); it has trailed the market most in October (−3.8 pts).
“vs S&P” is Medtronic PLC’s average for a month minus the S&P 500’s average for that same month — isolating Medtronic 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 90% across the last 10 years — the pattern is holding.
Figures are the typical (median) July 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: July, up in 9 of 10 Julys while the other eleven tend to blur together.
Its average (+2.3%) and median (+2.9%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 2.9% spread). Set against the S&P 500, mind, July is close to a wash — the gain mirrors the market more than it beats it. 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, February, and April have also closed higher more often than not. On the other side of the ledger, October has been the soft spot — the weakest of 4 months that average a loss (−2.7%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, December, and September. Its roughest month on record was a −14.7% February in 2020 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 8 years running. 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: July aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (July), its worst (October), and whether it really trades seasonally.

It's the weakest, averaging −2.7% — historically a soft spot, though it still varies from year to year.
