Strip the year back and a single month does the heavy lifting: January, up in all 4 Januaries while the other eleven tend to blur together.

Its average (+13.7%) and median (+15.0%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 8.3% spread), and even its worst January in 5 years lost only 1.6% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: January has cleared the S&P 500 by +13.9 points above the index. That consistency sets it apart from the field, where the average stock manages January only about 53% of the time.

A few other months pull their weight: April, May, and June have also closed higher more often than not. At the other end of the calendar, March has been the soft spot — the weakest of 5 months that average a loss (−5.3%), and the edge isn't year-round — the stock has trailed the S&P 500 in February, April, and October. Its roughest month on record was a −29.1% August in 2022 — a reminder of how hard even a seasonal name can fall.

The takeaway is less about when to buy than what to expect: January aside, the stock's months offer little reliable tilt. With a short 5-year record and returns that swing hard year to year, the signal is best held loosely.
