Month by month
The stock's clearest edge over the S&P 500 lands in June (+12.0 pts); it has trailed the market most in December (−7.7 pts).
“vs S&P” is STAAR Surgical Company’s average for a month minus the S&P 500’s average for that same month — isolating STAAR Surgical Company’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.
The headline flatters a touch — its +12.3% average sits well above the +7.4% a typical year delivers, the work of a few big Junes. That reliability comes with real swings, mind — even June ranges by 17.1% 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: June has cleared the S&P 500 by +12.0 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: March, April, and August have also closed higher more often than not. On the other side of the ledger, December has been the soft spot — the weakest of 3 months that average a loss (−6.7%), and the edge isn't year-round — the stock has trailed the S&P 500 in December, February, and November. Its roughest month on record was a −29.1% April in 2022 — a reminder of how hard even a seasonal name can fall.
At its steadiest, June strung together 7 straight positive years. 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. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (December), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (June, +12.3%) has run well ahead of its worst (December, −6.7%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +12.3% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −6.7% — historically a soft spot, though it still varies from year to year.
