Month by month
The stock's clearest edge over the S&P 500 lands in October (+4.5 pts); it has trailed the market most in March (−6.1 pts).
“vs S&P” is South Plains Financial Inc’s average for a month minus the S&P 500’s average for that same month — isolating South Plains Financial 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 86% across the last 7 years — the pattern is holding.
Figures are the typical (median) October return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
The seasonal story is really one month's story — October. It has closed higher in 6 of 7 Octobers, a concentration the rest of the calendar can't touch.
A typical October brings +3.6%, a shade under the +5.5% average. Better still, that strength is the stock's own and not just a buoyant market — October has outpaced the S&P 500 by +4.5 points on average. 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-January window has been the stock's reliable season. On the other side of the ledger, February has been the soft spot — the weakest of 4 months that average a loss (−2.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, April, and February. Its roughest month on record was a −22.2% March in 2020 — a reminder of how hard even a seasonal name can fall.
One run worth flagging just ended: a 6-year streak of positive Octobers was snapped by a −4.5% close in 2025. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
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. With a short 7-year record, the signal is best held loosely.
Short answers on the stock's best month (October), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (October, +5.5%) has run well ahead of its worst (February, −2.8%) — the heatmap above shows how steady that gap has been year to year.
October has been the strongest, averaging +5.5% and closing higher in 6 of 7 years since 2019.
It's the weakest, averaging −2.8% — historically a soft spot, though it still varies from year to year.
