Month by month
The stock's clearest edge over the S&P 500 lands in December (+5.9 pts); it has trailed the market most in April (−6.9 pts).
“vs S&P” is Astrotech Corp’s average for a month minus the S&P 500’s average for that same month — isolating Astrotech Corp’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, February has closed higher 80% of the time versus 60% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) February 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 year leans February's way without overwhelming the rest of it: the stock has closed higher in 6 of 10 Februaries, its most dependable month if not a dominant one.
Its average (+1.7%) and median (+3.5%) 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 6.4% spread), and even its worst February in 10 years lost only 7.7% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: February has cleared the S&P 500 by +2.0 points above the index. It bucks the broad tape, besides: February lifts just 49% of stocks across the market.
Only July comes anywhere near it for reliability. The weaker half of the year is plainer: September has been the soft spot — the weakest of 7 months that average a loss (−6.3%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, November, and September. Its roughest month on record was a −42.3% April in 2021 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Februaries run ahead of the earlier years.
Treat it as a tendency rather than a rule — seasonality describes the past, not a promise. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (February), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (February, +1.7%) has run well ahead of its worst (September, −6.3%) — the heatmap above shows how steady that gap has been year to year.
February has been the strongest, averaging +1.7% and closing higher in 6 of 10 years since 2016.
It's the weakest, averaging −6.3% — historically a soft spot, though it still varies from year to year.
