Month by month
The stock's clearest edge over the S&P 500 lands in December (+1.2 pts); it has trailed the market most in October (−2.6 pts).
“vs S&P” is Fomento Economico Mexicano’s average for a month minus the S&P 500’s average for that same month — isolating Fomento Economico Mexicano’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, March has closed higher 100% of the time versus 80% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) March 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
Dependability is the through-line here. March stands out, higher in 8 of 10 Marches, but it heads a clutch of months that pull the year reliably upward.
Its average (+0.8%) and median (+3.3%) 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 March ranges by 10.0% from year to year, so any single year can land far from the average. Set against the S&P 500, mind, March 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 March only about 56% of the time.
The strength clusters rather than stands alone — March–June forms a firm stretch that carries much of the year. The weaker half of the year is plainer: October has been the soft spot — the only month to average an outright loss (−1.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, July, and August.
March has now closed higher 5 years running. If anything it has sharpened recently — the last five Marches run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: March aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (March), its worst (October), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — March is the firmest (+0.8%) and October the softest (−1.6%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
March has been the strongest, averaging +0.8% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −1.6% — historically a soft spot, though it still varies from year to year.
