Month by month
The stock's clearest edge over the S&P 500 lands in November (+9.5 pts); it has trailed the market most in September (−3.4 pts).
“vs S&P” is Fair Isaac Corporation’s average for a month minus the S&P 500’s average for that same month — isolating Fair Isaac Corporation’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 80% of the time versus 90% across the last 10 years — the pattern is holding.
Figures are the typical (median) June 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
Dependability is the through-line here. June stands out, higher in 9 of 10 Junes, but it heads a clutch of months that pull the year reliably upward.
A typical June brings +2.8%, a shade under the +4.0% average. It is also the calendar's calmest month, its returns swinging least from year to year (a 4.6% spread), and even its worst June in 10 years lost only 1.3% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: June has cleared the S&P 500 by +3.8 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
The strength clusters rather than stands alone — April–July forms a firm stretch that carries much of the year. The weaker half of the year is plainer: September has been the soft spot — the weakest of 2 months that average a loss (−3.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, March, and October. Its roughest month on record was a −22.1% July in 2025 — 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.
The takeaway is less about when to buy than what to expect: June aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (June), its worst (September), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (June, +4.0%) has run well ahead of its worst (September, −3.6%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +4.0% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −3.6% — historically a soft spot, though it still varies from year to year.
