Reality check
Over the last 5 years, July has closed higher 100% of the time versus 90% across the last 10 years — the pattern is holding.

In plain English
The seasonal story is really one month's story — July. It has closed higher in 9 of 10 Julys, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+2.3%) and median (+2.4%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: July's returns vary by just 3.1% year to year. Set against the S&P 500, mind, July is close to a wash — the gain mirrors the market more than it beats it. Few peers keep such company in July — the typical stock clears it just 61% of the time.
It doesn't stand entirely alone — January, March, and November have leaned firm as well, if less emphatically. At the other end of the calendar, August has been the soft spot — the weakest of 6 months that average a loss (−2.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in August, April, and May. Its roughest month on record was a −13.7% September in 2023 — a reminder of how hard even a seasonal name can fall.
July has now closed higher 6 years running. 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.
Short answers on the stock's best month (July), its worst (August), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (July, +2.3%) has run well ahead of its worst (August, −2.4%) — the heatmap above shows how steady that gap has been year to year.
