Month by month
The stock's clearest edge over the S&P 500 lands in June (+2.1 pts); it has trailed the market most in September (−4.2 pts).
“vs S&P” is The Clorox Company’s average for a month minus the S&P 500’s average for that same month — isolating The Clorox Company’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 80% of the time versus 80% across the last 10 years — the pattern is holding.
Figures are the typical (median) June 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. June stands out, higher in 8 of 10 Junes, but it heads a clutch of months that pull the year reliably upward.
A typical June brings +1.1%, a shade under the +2.3% average. Crucially, the gain is the stock's own rather than a rising tide's: June has cleared the S&P 500 by +2.1 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
The strength clusters rather than stands alone — May–July forms a firm stretch that carries much of the year. On the other side of the ledger, October has been the soft spot — the weakest of 3 months that average a loss (−1.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, October, and April. Its roughest month on record was a −15.6% September in 2023 — a reminder of how hard even a seasonal name can fall.
A long streak recently broke — June had risen 7 years straight before a −7.8% reading in 2025. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
The takeaway is less about when to buy than what to expect: June aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (June), its worst (October), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (June, +2.3%) has run well ahead of its worst (October, −1.5%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +2.3% 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.
