Month by month
The stock's clearest edge over the S&P 500 lands in August (+13.4 pts); it has trailed the market most in December (−7.3 pts).
“vs S&P” is Lithium Argentina AG’s average for a month minus the S&P 500’s average for that same month — isolating Lithium Argentina AG’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, September has closed higher 60% of the time versus 70% across the last 10 years — the pattern is weakening.
Figures are the typical (median) September 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
Dependability is the through-line here. September stands out, higher in 7 of 10 Septembers, but it heads a clutch of months that pull the year reliably upward.
The headline flatters a touch — its +11.1% average sits well above the +5.0% a typical year delivers, the work of a few big Septembers. That reliability comes with real swings, mind — even September ranges by 16.7% 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: September has cleared the S&P 500 by +11.2 points above the index. It bucks the broad tape, besides: September lifts just 39% of stocks across the market.
A few other months pull their weight: May, August, and November have also closed higher more often than not. On the other side of the ledger, April 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 December, October, and April. Its roughest month on record was a −39.1% March in 2020 — a reminder of how hard even a seasonal name can fall.
The pattern has softened of late, September's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: September aside, the stock's months offer little reliable tilt. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (September), its worst (April), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (September, +11.1%) has run well ahead of its worst (April, −0.4%) — the heatmap above shows how steady that gap has been year to year.
September has been the strongest, averaging +11.1% and closing higher in 7 of 10 years since 2016.
It's the weakest, averaging −0.4% — historically a soft spot, though it still varies from year to year.
