Month by month
The stock's clearest edge over the S&P 500 lands in October (+4.2 pts); it has trailed the market most in February (−3.8 pts).
“vs S&P” is ICICI Bank Limited’s average for a month minus the S&P 500’s average for that same month — isolating ICICI Bank Limited’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, October has closed higher 60% of the time versus 80% across the last 10 years — the pattern is weakening.
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
Dependability is the through-line here. October stands out, higher in 8 of 10 Octobers, but it heads a clutch of months that pull the year reliably upward.
Its average (+5.3%) and median (+5.7%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 4.8% spread). Crucially, the gain is the stock's own rather than a rising tide's: October has cleared the S&P 500 by +4.2 points above the index. That consistency sets it apart from the field, where the average stock manages October only about 53% of the time.
The strength clusters rather than stands alone — October–December forms a firm stretch that carries much of the year. At the other end of the calendar, February has been the soft spot — the weakest of 2 months that average a loss (−4.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, September, and November. Its roughest month on record was a −39.8% March in 2020 — a reminder of how hard even a seasonal name can fall.
At its steadiest, October strung together 7 straight positive years. The pattern has softened of late, October's last five years slipping below its longer-run record.
The takeaway is less about when to buy than what to expect: October aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (October), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (October, +5.3%) has run well ahead of its worst (February, −4.1%) — the heatmap above shows how steady that gap has been year to year.
October has been the strongest, averaging +5.3% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −4.1% — historically a soft spot, though it still varies from year to year.
