Month by month
The stock's clearest edge over the S&P 500 lands in February (+3.1 pts); it has trailed the market most in May (−1.7 pts).
“vs S&P” is Huntington Ingalls Industries Inc’s average for a month minus the S&P 500’s average for that same month — isolating Huntington Ingalls Industries Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, October has closed higher 80% of the time versus 80% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) October 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 October is the anchor — it has closed higher in 8 of 10 Octobers, the steadiest beat on its year.
The strength looks broad-based rather than freakish: its average (+1.5%) and median (+5.2%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even October ranges by 13.0% from year to year, so any single year can land far from the average. Set against the S&P 500, mind, October is close to a wash — the gain mirrors the market more than it beats it. Few peers keep such company in October — the typical stock clears it just 53% of the time.
October anchors a run, too: the October-through-February window has been the stock's reliable season. At the other end of the calendar, March is the year's low point, though even there the stock has stayed positive on average (+0.6%), a sign every month leans up, and the edge isn't year-round — the stock has trailed the S&P 500 in May and September.
If anything it has sharpened recently — the last five Octobers run ahead of the earlier years.
For a stock this dependable in October, 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 (October), its worst (March), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — October is the firmest (+1.5%) and March the softest (+0.6%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
October has been the strongest, averaging +1.5% and closing higher in 8 of 10 years since 2016.
It's the weakest month, but it has still averaged a small gain (+0.6%) — quiet rather than genuinely bad.
