Month by month
The stock's clearest edge over the S&P 500 lands in November (+7.0 pts); it has trailed the market most in March (−4.9 pts).
“vs S&P” is Marriott International Inc’s average for a month minus the S&P 500’s average for that same month — isolating Marriott International Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, April has closed higher 80% of the time versus 90% across the last 10 years — the pattern is weakening.
Figures are the typical (median) April 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 April is the anchor — it has closed higher in 9 of 10 Aprils, the steadiest beat on its year.
Read it with one caveat: the average (+4.8%) runs well ahead of the median (+2.6%), so a handful of outsized years — not steady strength — do much of the lifting. That reliability comes with real swings, mind — even April ranges by 9.5% 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 — April has outpaced the S&P 500 by +3.1 points on average. Few peers keep such company in April — the typical stock clears it just 55% of the time.
It doesn't stand entirely alone — January, February, and July have leaned firm as well, if less emphatically. On the other side of the ledger, May is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the stock has trailed the S&P 500 in March, June, and May. Its roughest month on record was a −39.2% March in 2020 — a reminder of how hard even a seasonal name can fall.
At its steadiest, April strung together 8 straight positive years. The pattern has softened of late, April's last five years slipping below its longer-run record.
For a stock this dependable in April, 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 (April), its worst (May), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (April, +4.8%) has run well ahead of its worst (May, 0.0%) — the heatmap above shows how steady that gap has been year to year.
April has been the strongest, averaging +4.8% and closing higher in 9 of 10 years since 2016.
It's the weakest month, but it has still averaged a small gain (0.0%) — quiet rather than genuinely bad.
