Month by month
The stock's clearest edge over the S&P 500 lands in July (+4.3 pts); it has trailed the market most in March (−3.4 pts).
“vs S&P” is Radian Group Inc’s average for a month minus the S&P 500’s average for that same month — isolating Radian Group Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, October has closed higher 80% of the time versus 80% across the last 10 years — the pattern is holding.
Figures are the typical (median) October 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
The seasonal story is really one month's story — October. It has closed higher in 8 of 10 Octobers, a concentration the rest of the calendar can't touch.
Read it with one caveat: the average (+4.2%) runs well ahead of the median (+2.2%), so a handful of outsized years — not steady strength — do much of the lifting. Better still, that strength is the stock's own and not just a buoyant market — October has outpaced the S&P 500 by +3.2 points on average. Few peers keep such company in October — the typical stock clears it just 53% of the time.
It doesn't stand entirely alone — January, March, and May have leaned firm as well, if less emphatically. On the other side of the ledger, June has been the soft spot — the weakest of 4 months that average a loss (−2.7%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, June, and September. Its roughest month on record was a −43.0% March in 2020 — a reminder of how hard even a seasonal name can fall.
One run worth flagging just ended: a 6-year streak of positive Octobers was snapped by a −4.6% close in 2025. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
For a stock this dependable in October, 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 (October), its worst (June), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (October, +4.2%) has run well ahead of its worst (June, −2.7%) — the heatmap above shows how steady that gap has been year to year.
October has been the strongest, averaging +4.2% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −2.7% — historically a soft spot, though it still varies from year to year.
