Month by month
The stock's clearest edge over the S&P 500 lands in April (+6.1 pts); it has trailed the market most in July (−4.2 pts).
“vs S&P” is Ardmore Shpng’s average for a month minus the S&P 500’s average for that same month — isolating Ardmore Shpng’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, March has closed higher 80% of the time versus 80% across the last 10 years — the pattern is holding.
Figures are the typical (median) March 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: March, up in 8 of 10 Marches while the other eleven tend to blur together.
Its average (+3.0%) and median (+2.8%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 10.2% spread). Crucially, the gain is the stock's own rather than a rising tide's: March has cleared the S&P 500 by +2.0 points above the index. That consistency sets it apart from the field, where the average stock manages March only about 56% of the time.
A few other months pull their weight: April and September have also closed higher more often than not. At the other end of the calendar, January has been the soft spot — the weakest of 5 months that average a loss (−3.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in July, November, and June. Its roughest month on record was a −31.4% January in 2020 — a reminder of how hard even a seasonal name can fall.
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: March 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 (March), its worst (January), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (March, +3.0%) has run well ahead of its worst (January, −3.4%) — the heatmap above shows how steady that gap has been year to year.
March has been the strongest, averaging +3.0% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −3.4% — historically a soft spot, though it still varies from year to year.
