Month by month
The stock's clearest edge over the S&P 500 lands in March (+3.6 pts); it has trailed the market most in September (−1.8 pts).
“vs S&P” is WEC Energy Group Inc’s average for a month minus the S&P 500’s average for that same month — isolating WEC Energy Group Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, March has closed higher 100% of the time versus 90% 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 9 of 10 Marches, but it heads a clutch of months that pull the year reliably upward.
Its average (+4.7%) and median (+5.0%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Crucially, the gain is the stock's own rather than a rising tide's: March has cleared the S&P 500 by +3.6 points above the index. That consistency sets it apart from the field, where the average stock manages March only about 56% of the time.
A few other months pull their weight: January, April, and July have also closed higher more often than not. The weaker half of the year is plainer: December is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the stock has trailed the S&P 500 in September, December, and November. Its roughest month on record was a −14.5% September in 2022 — a reminder of how hard even a seasonal name can fall.
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 (December), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (March, +4.7%) has run well ahead of its worst (December, −0.5%) — the heatmap above shows how steady that gap has been year to year.
March has been the strongest, averaging +4.7% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −0.5% — historically a soft spot, though it still varies from year to year.
