Month by month
The stock's clearest edge over the S&P 500 lands in January (+5.4 pts); it has trailed the market most in March (−3.6 pts).
“vs S&P” is Bright Horizons Family Solutions Inc’s average for a month minus the S&P 500’s average for that same month — isolating Bright Horizons Family Solutions Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, January has closed higher 80% of the time versus 90% across the last 10 years — the pattern is holding.
Figures are the typical (median) January 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 — January. It has closed higher in 9 of 10 Januaries, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+5.2%) and median (+5.1%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: January's returns vary by just 6.1% year to year. Better still, that strength is the stock's own and not just a buoyant market — January has outpaced the S&P 500 by +5.4 points on average. Few peers keep such company in January — the typical stock clears it just 53% of the time.
January anchors a run, too: the January-through-March window has been the stock's reliable season. The weaker half of the year is plainer: September has been the soft spot — the weakest of 4 months that average a loss (−2.9%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, September, and April. Its roughest month on record was a −36.0% March in 2020 — a reminder of how hard even a seasonal name can fall.
Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
For a stock this dependable in January, 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 (January), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (January, +5.2%) has run well ahead of its worst (September, −2.9%) — the heatmap above shows how steady that gap has been year to year.
January has been the strongest, averaging +5.2% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −2.9% — historically a soft spot, though it still varies from year to year.
