Month by month
The stock's clearest edge over the S&P 500 lands in August (+5.3 pts); it has trailed the market most in October (−4.9 pts).
“vs S&P” is Mednax Inc’s average for a month minus the S&P 500’s average for that same month — isolating Mednax 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 70% across the last 10 years — the pattern is strengthening.
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
Strip the year back and a single month does the heavy lifting: June, up in 7 of 10 Junes while the other eleven tend to blur together.
Its average (+2.9%) and median (+4.1%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 5.3% spread), and even its worst June in 10 years lost only 7.1% — 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 +2.7 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
A few other months pull their weight: November and December have also closed higher more often than not. At the other end of the calendar, February has been the soft spot — the weakest of 6 months that average a loss (−4.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, March, and February. Its roughest month on record was a −33.2% March in 2020 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Junes run ahead of the earlier years.
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 (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (June, +2.9%) has run well ahead of its worst (February, −4.5%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +2.9% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −4.5% — historically a soft spot, though it still varies from year to year.
