Month by month
The stock's clearest edge over the S&P 500 lands in February (+10.8 pts); it has trailed the market most in May (−5.5 pts).
“vs S&P” is Anterix Inc’s average for a month minus the S&P 500’s average for that same month — isolating Anterix Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 60% of the time versus 70% 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
This is a stock you can almost set a calendar by, and November is the anchor — it has closed higher in 7 of 10 Novembers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+1.9%) and median (+3.7%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: November's returns vary by just 7.0% year to year. Set against the S&P 500, mind, November is close to a wash — the gain mirrors the market more than it beats it. Some of that is a strong month market-wide, mind — November rises for about 62% of stocks — so the tendency is real if not unique.
It doesn't stand entirely alone — February and August have leaned firm as well, if less emphatically. On the other side of the ledger, June is the year's quietest corner, essentially flat on average, and the edge isn't year-round — the stock has trailed the S&P 500 in May, September, and January. Its roughest month on record was a −41.4% May in 2016 — 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.
For a stock this dependable in November, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
Short answers on the stock's best month (November), its worst (June), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — November is the firmest (+1.9%) and June the softest (−0.3%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
November has been the strongest, averaging +1.9% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −0.3% — historically a soft spot, though it still varies from year to year.
