Month by month
The stock's clearest edge over the S&P 500 lands in July (+3.5 pts); it has trailed the market most in March (−1.2 pts).
“vs S&P” is Service Corporation International’s average for a month minus the S&P 500’s average for that same month — isolating Service Corporation International’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 80% of the time versus 80% 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
Dependability is the through-line here. July stands out, higher in 8 of 10 Julys, but it heads a clutch of months that pull the year reliably upward.
Its average (+5.6%) and median (+5.5%) 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: July has cleared the S&P 500 by +3.5 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 — May–August forms a firm stretch that carries much of the year. At the other end of the calendar, February has been the soft spot — the weakest of 3 months that average a loss (−1.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, February, and August. Its roughest month on record was a −22.1% March in 2020 — a reminder of how hard even a seasonal name can fall.
A long streak recently broke — July had risen 5 years straight before a −7.1% 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 (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (July, +5.6%) has run well ahead of its worst (February, −1.4%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +5.6% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −1.4% — historically a soft spot, though it still varies from year to year.
