Month by month
Across the year the stock has stayed close to the S&P 500 — no single month stands out as a real edge.
“vs S&P” is The Southern Company’s average for a month minus the S&P 500’s average for that same month — isolating The Southern Company’s own seasonal edge from broad market drift.
Reality check
Not enough recent November history to say whether the pattern still holds.
Figures are the typical (median) November return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-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 all 1 Novembers while the other eleven tend to blur together.
Its average (+2.1%) and median (+2.1%) 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 0.0% spread), and even its worst November in 1 years lost only 2.1% — the gentlest downside anywhere on its calendar. Set against the S&P 500, mind, November is close to a wash — the gain mirrors the market more than it beats it. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
Only December comes anywhere near it for reliability. At the other end of the calendar, December is the year's low point, though even there the stock has stayed positive on average (+0.7%), a sign every month leans up.
The takeaway is less about when to buy than what to expect: November aside, the stock's months offer little reliable tilt. With a short 1-year record, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (December), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — November is the firmest (+2.1%) and December the softest (+0.7%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
November has been the strongest, averaging +2.1% and closing higher in its one year on record since 2025.
It's the weakest month, but it has still averaged a small gain (+0.7%) — quiet rather than genuinely bad.
