Month by month
The stock's clearest edge over the S&P 500 lands in July (+4.5 pts); it has trailed the market most in December (−1.3 pts).
“vs S&P” is Lincoln Electric Holdings Inc’s average for a month minus the S&P 500’s average for that same month — isolating Lincoln Electric Holdings Inc’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 strengthening.
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
Dependability is the through-line here. July stands out, higher in 9 of 10 Julys, but it heads a clutch of months that pull the year reliably upward.
Its average (+6.7%) and median (+6.5%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 6.1% spread). Crucially, the gain is the stock's own rather than a rising tide's: July has cleared the S&P 500 by +4.5 points above the index. That consistency sets it apart from the field, where the average stock manages July only about 61% of the time.
The strength clusters rather than stands alone — June–August forms a firm stretch that carries much of the year. On the other side of the ledger, September has been the soft spot — the only month to average an outright loss (−1.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in December, March, and May. Its roughest month on record was a −18.4% March in 2020 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 8 years running. If anything it has sharpened recently — the last five Julys run ahead of the earlier years.
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 (September), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (July, +6.7%) has run well ahead of its worst (September, −1.1%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +6.7% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −1.1% — historically a soft spot, though it still varies from year to year.
