Month by month
The stock's clearest edge over the S&P 500 lands in May (+3.8 pts); it has trailed the market most in February (−3.9 pts).
“vs S&P” is CorVel Corp’s average for a month minus the S&P 500’s average for that same month — isolating CorVel Corp’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, May has closed higher 40% of the time versus 70% across the last 10 years — the pattern is weakening.
Figures are the typical (median) May 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. May stands out, higher in 7 of 10 Mays, but it heads a clutch of months that pull the year reliably upward.
The headline flatters a touch — its +4.5% average sits well above the +2.7% a typical year delivers, the work of a few big Mays. That reliability comes with real swings, mind — even May ranges by 9.9% 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: May 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 May only about 55% of the time.
The strength clusters rather than stands alone — March–May forms a firm stretch that carries much of the year. On the other side of the ledger, February has been the soft spot — the weakest of 3 months that average a loss (−4.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, March, and September. Its roughest month on record was a −24.1% February in 2020 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, May's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: May aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (May), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (May, +4.5%) has run well ahead of its worst (February, −4.2%) — the heatmap above shows how steady that gap has been year to year.
May has been the strongest, averaging +4.5% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −4.2% — historically a soft spot, though it still varies from year to year.
