Month by month

“vs S&P” is McGraw Hill, Inc.’s average for a month minus the S&P 500’s average for that same month — isolating McGraw Hill, Inc.’s own seasonal edge from broad market drift.
Reality check
Not enough recent November history to say whether the pattern still holds.
Figures are the typical (median) November return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Strip the year back and a single month does the heavy lifting: November, up in all 1 Novembers while the other eleven tend to blur together.
Its average (+61.0%) and median (+61.0%) 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 0.0% spread), and even its worst November in 1 years lost only 61.0% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: November has cleared the S&P 500 by +58.7 points above the index. That consistency sets it apart from the field, where the average stock manages November only about 62% of the time.
No other month comes close to matching it — the rest of the calendar is unremarkable by comparison. On the other side of the ledger, September has been the soft spot — the weakest of 5 months that average a loss (−11.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, October, and July. Its roughest month on record was a −11.6% September in 2025 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: November aside, the stock's months offer little reliable tilt. With a short 1-year record, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (November, +61.0%) has run well ahead of its worst (September, −11.6%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +61.0% and closing higher in its one year on record since 2025.
It's the weakest, averaging −11.6% — historically a soft spot, though it still varies from year to year.
