Month by month
The stock's clearest edge over the S&P 500 lands in March (+6.8 pts); it has trailed the market most in December (−5.2 pts).
“vs S&P” is Preformed Line Products Company’s average for a month minus the S&P 500’s average for that same month — isolating Preformed Line Products Company’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, October has closed higher 80% of the time versus 80% across the last 10 years — the pattern is holding.
Figures are the typical (median) October 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. October stands out, higher in 8 of 10 Octobers, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.3%) 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. It is among its calmest months, too, its returns swinging least from year to year (a 8.3% spread). Set against the S&P 500, mind, October 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 October only about 53% of the time.
A few other months pull their weight: March, May, and July have also closed higher more often than not. On the other side of the ledger, February has been the soft spot — the weakest of 3 months that average a loss (−4.7%), and the edge isn't year-round — the stock has trailed the S&P 500 in December, February, and January. Its roughest month on record was a −16.6% December in 2018 — a reminder of how hard even a seasonal name can fall.
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: October aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (October), its worst (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (October, +1.3%) has run well ahead of its worst (February, −4.7%) — the heatmap above shows how steady that gap has been year to year.
October has been the strongest, averaging +1.3% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −4.7% — historically a soft spot, though it still varies from year to year.
