Month by month
The stock's clearest edge over the S&P 500 lands in January (+5.2 pts); it has trailed the market most in November (−2.6 pts).
“vs S&P” is Banco De Chile’s average for a month minus the S&P 500’s average for that same month — isolating Banco De Chile’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, March has closed higher 100% of the time versus 80% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) March 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
Strip the year back and a single month does the heavy lifting: March, up in 8 of 10 Marches while the other eleven tend to blur together.
Its average (+3.5%) and median (+3.6%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Crucially, the gain is the stock's own rather than a rising tide's: March has cleared the S&P 500 by +2.5 points above the index. That consistency sets it apart from the field, where the average stock manages March only about 56% of the time.
The strength clusters rather than stands alone — November–April forms a firm stretch that carries much of the year. On the other side of the ledger, May has been the soft spot — the weakest of 4 months that average a loss (−1.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in November, May, and October. Its roughest month on record was a −21.3% November in 2019 — a reminder of how hard even a seasonal name can fall.
March has now closed higher 5 years running. If anything it has sharpened recently — the last five Marches run ahead of the earlier years.
The takeaway is less about when to buy than what to expect: March aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (March), its worst (May), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (March, +3.5%) has run well ahead of its worst (May, −1.5%) — the heatmap above shows how steady that gap has been year to year.
March has been the strongest, averaging +3.5% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −1.5% — historically a soft spot, though it still varies from year to year.
