Month by month
The stock's clearest edge over the S&P 500 lands in May (+15.0 pts); it has trailed the market most in March (−11.1 pts).
“vs S&P” is Datadog Inc’s average for a month minus the S&P 500’s average for that same month — isolating Datadog Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 80% of the time versus 83% across the last 7 years — the pattern is holding.
Figures are the typical (median) June return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-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 June is the anchor — it has closed higher in 5 of 6 Junes, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+12.1%) and median (+13.7%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even June ranges by 9.1% 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 — June has outpaced the S&P 500 by +11.8 points on average. Few peers keep such company in June — the typical stock clears it just 52% of the time.
June anchors a run, too: the May-through-August window has been the stock's reliable season. At the other end of the calendar, March has been the soft spot — the weakest of 3 months that average a loss (−10.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, December, and February. Its roughest month on record was a −21.3% April in 2022 — 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.
For a stock this dependable in June, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 7-year record, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (March), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (June, +12.1%) has run well ahead of its worst (March, −10.1%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +12.1% and closing higher in 5 of 6 years since 2019.
It's the weakest, averaging −10.1% — historically a soft spot, though it still varies from year to year.
