Month by month
The stock's clearest edge over the S&P 500 lands in December (+8.4 pts); it has trailed the market most in May (−13.5 pts).
“vs S&P” is Marin Software Inc’s average for a month minus the S&P 500’s average for that same month — isolating Marin Software Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, December has closed higher 60% of the time versus 60% across the last 10 years — the pattern is holding.
Figures are the typical (median) December 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 feast-or-famine calendar. December reads as the strong month, higher in 6 of 10 Decembers, but the tale is one of a few outsized years more than steady gains.
Read it with one caveat: the average (+9.4%) runs well ahead of the median (+1.8%), so a handful of outsized years — not steady strength — do much of the lifting. That reliability comes with real swings, mind — even December ranges by 35.3% 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 — December has outpaced the S&P 500 by +8.4 points on average.
On the other side of the ledger, May has been the soft spot — the weakest of 9 months that average a loss (−12.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in May, February, and March. Its roughest month on record was a −56.3% May in 2019 — 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.
Hold it loosely, then: the December tendency is genuine but lumpy, more about the occasional outsized year than a gain to bank on. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (December), its worst (May), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (December, +9.4%) has run well ahead of its worst (May, −12.8%) — the heatmap above shows how steady that gap has been year to year.
December has been the strongest, averaging +9.4% and closing higher in 6 of 10 years since 2016.
It's the weakest, averaging −12.8% — historically a soft spot, though it still varies from year to year.
