Month by month
The stock's clearest edge over the S&P 500 lands in November (+9.2 pts); it has trailed the market most in March (−4.8 pts).
“vs S&P” is Digi International Inc’s average for a month minus the S&P 500’s average for that same month — isolating Digi International Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 80% of the time versus 90% across the last 10 years — the pattern is holding.
Figures are the typical (median) November 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: November, up in 9 of 10 Novembers while the other eleven tend to blur together.
Its average (+11.5%) and median (+12.7%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. That reliability comes with real swings, mind — even November ranges by 11.7% 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: November has cleared the S&P 500 by +9.2 points above the index. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
A few other months pull their weight: May, June, and July have also closed higher more often than not. On the other side of the ledger, January has been the soft spot — the weakest of 4 months that average a loss (−3.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, October, and January. Its roughest month on record was a −28.4% March 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: November aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (November), its worst (January), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (November, +11.5%) has run well ahead of its worst (January, −3.1%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +11.5% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −3.1% — historically a soft spot, though it still varies from year to year.
