Reality check
Over the last 5 years, July has closed higher 80% of the time versus 80% across the last 10 years — the pattern is holding.
Figures are the typical (median) July 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
The seasonal story is really one month's story — July. It has closed higher in 8 of 10 Julys, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+5.1%) and median (+3.7%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: July's returns vary by just 9.3% year to year, and even its worst July in 10 years lost only 6.8% — the gentlest downside anywhere on its calendar. Better still, that strength is the stock's own and not just a buoyant market — July has outpaced the S&P 500 by +3.0 points on average. Few peers keep such company in July — the typical stock clears it just 61% of the time.
It doesn't stand entirely alone — February, March, and April have leaned firm as well, if less emphatically. At the other end of the calendar, June has been the soft spot — the weakest of 6 months that average a loss (−2.9%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, October, and June. Its roughest month on record was a −36.7% April in 2016 — a reminder of how hard even a seasonal name can fall.
One run worth flagging just ended: a 5-year streak of positive Julys was snapped by a −4.9% 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 July, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (July), its worst (June), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (July, +5.1%) has run well ahead of its worst (June, −2.9%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +5.1% and closing higher in 8 of 10 years since 2016.
