Month by month
The stock's clearest edge over the S&P 500 lands in August (+41.8 pts); it has trailed the market most in October (−10.4 pts).
“vs S&P” is Fulcrum Therapeutics Inc’s average for a month minus the S&P 500’s average for that same month — isolating Fulcrum Therapeutics Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, November has closed higher 80% of the time versus 86% across the last 7 years — the pattern is holding.
Figures are the typical (median) November return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-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 — November. It has closed higher in 6 of 7 Novembers, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+25.5%) and median (+21.3%) sit close together, so no single blow-out year is flattering the figure. That reliability comes with real swings, mind — even November ranges by 36.9% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — November has outpaced the S&P 500 by +23.2 points on average. Few peers keep such company in November — the typical stock clears it just 62% of the time.
Only December comes anywhere near it for reliability. The weaker half of the year is plainer: October has been the soft spot — the weakest of 6 months that average a loss (−9.4%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, April, and September. Its roughest month on record was a −59.5% April in 2022 — 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 November, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 7-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (November), its worst (October), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (November, +25.5%) has run well ahead of its worst (October, −9.4%) — the heatmap above shows how steady that gap has been year to year.
November has been the strongest, averaging +25.5% and closing higher in 6 of 7 years since 2019.
It's the weakest, averaging −9.4% — historically a soft spot, though it still varies from year to year.
