Month by month
The stock's clearest edge over the S&P 500 lands in July (+4.9 pts); it has trailed the market most in March (−4.1 pts).
“vs S&P” is Matson Inc’s average for a month minus the S&P 500’s average for that same month — isolating Matson Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 80% of the time versus 70% 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
This is a stock you can almost set a calendar by, and July is the anchor — it has closed higher in 7 of 10 Julys, the steadiest beat on its year.
Read it with one caveat: the average (+7.1%) runs well ahead of the median (+4.3%), so a handful of outsized years — not steady strength — do much of the lifting. That reliability comes with real swings, mind — even July ranges by 12.4% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — July has outpaced the S&P 500 by +4.9 points on average. Some of that is a strong month market-wide, mind — July rises for about 61% of stocks — so the tendency is real if not unique.
It doesn't stand entirely alone — January, February, and October have leaned firm as well, if less emphatically. The weaker half of the year is plainer: March has been the soft spot — the weakest of 3 months that average a loss (−3.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, April, and August. Its roughest month on record was a −25.6% April in 2022 — a reminder of how hard even a seasonal name can fall.
One run worth flagging just ended: a 6-year streak of positive Julys was snapped by a −6.7% close in 2025. If anything it has sharpened recently — the last five Julys run ahead of the earlier years.
For a stock this dependable in July, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
Short answers on the stock's best month (July), its worst (March), and whether it really trades seasonally.
