Month by month
The stock's clearest edge over the S&P 500 lands in October (+15.2 pts); it has trailed the market most in April (−8.6 pts).
“vs S&P” is Cloudflare Inc’s average for a month minus the S&P 500’s average for that same month — isolating Cloudflare Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, February has closed higher 80% of the time versus 83% across the last 7 years — the pattern is weakening.
Figures are the typical (median) February 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
Strip the year back and a single month does the heavy lifting: February, up in 5 of 6 Februaries while the other eleven tend to blur together.
Its average (+10.7%) and median (+10.9%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That reliability comes with real swings, mind — even February ranges by 10.4% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: February has cleared the S&P 500 by +10.9 points above the index. It bucks the broad tape, besides: February lifts just 49% of stocks across the market.
A few other months pull their weight: January, June, and July have also closed higher more often than not. The weaker half of the year is plainer: April has been the soft spot — the weakest of 4 months that average a loss (−7.0%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, December, and March. Its roughest month on record was a −37.7% May in 2022 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, February's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: February aside, the stock's months offer little reliable tilt. With a short 7-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (February), its worst (April), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (February, +10.7%) has run well ahead of its worst (April, −7.0%) — the heatmap above shows how steady that gap has been year to year.
February has been the strongest, averaging +10.7% and closing higher in 5 of 6 years since 2019.
It's the weakest, averaging −7.0% — historically a soft spot, though it still varies from year to year.
