Month by month
The stock's clearest edge over the S&P 500 lands in September (+21.0 pts); it has trailed the market most in August (−10.9 pts).
“vs S&P” is BridgeBio Oncology Therapeutics, Inc.’s average for a month minus the S&P 500’s average for that same month — isolating BridgeBio Oncology Therapeutics, Inc.’s own seasonal edge from broad market drift.
Reality check
Not enough recent September history to say whether the pattern still holds.
Figures are the typical (median) September 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
Dependability is the through-line here. September stands out, higher in all 1 Septembers, but it heads a clutch of months that pull the year reliably upward.
Its average (+20.9%) and median (+20.9%) 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 September in 1 years lost only 20.9% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: September has cleared the S&P 500 by +21.0 points above the index. It bucks the broad tape, besides: September lifts just 39% of stocks across the market.
A few other months pull their weight: November and December have also closed higher more often than not. The weaker half of the year is plainer: August has been the soft spot — the weakest of 2 months that average a loss (−10.6%), and the edge isn't year-round — the stock has trailed the S&P 500 in August, November, and October. Its roughest month on record was a −10.6% August 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: September 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 (September), its worst (August), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2025 its best month (September, +20.9%) has run well ahead of its worst (August, −10.6%) — the heatmap above shows how steady that gap has been year to year.
September has been the strongest, averaging +20.9% and closing higher in its one year on record since 2025.
It's the weakest, averaging −10.6% — historically a soft spot, though it still varies from year to year.
