Month by month
The stock's clearest edge over the S&P 500 lands in June (+5.7 pts); it has trailed the market most in March (−9.4 pts).
“vs S&P” is LCI Industries’s average for a month minus the S&P 500’s average for that same month — isolating LCI Industries’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 80% 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 (+6.8%) and median (+7.0%) 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 5.8% spread), and even its worst July in 10 years lost only 0.7% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: July has cleared the S&P 500 by +4.7 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 — April–July forms a firm stretch that carries much of the year. The weaker half of the year is plainer: March has been the soft spot — the weakest of 6 months that average a loss (−8.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, December, and October. Its roughest month on record was a −31.8% March in 2020 — a reminder of how hard even a seasonal name can fall.
A long streak recently broke — July had risen 9 years straight before a −0.7% reading in 2025. 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 (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (July, +6.8%) has run well ahead of its worst (March, −8.4%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +6.8% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −8.4% — historically a soft spot, though it still varies from year to year.
