The Pre-Print Cohort Read
Heading into the print, the live cohort_analyze pull on ABNB returned n=254 historical analogs with a tightness score of 0.58. The 5-day forward median was +0.53% with IQR [-2.03%, +3.35%] and hit-rate 55%. The 10-day median was +0.59% with IQR [-2.28%, +4.08%]. The dominant 5-day feature was macro_state=bullish (negative direction, importance 1.72).
What Actually Printed
Print-day close: $140.46, prior close $139.88. Day-over-day change: +0.41% (+0.58). Intraday range: $138.64 – $142.19.
Cohort vs. Reality — The Verdict
The +0.41% reaction is sitting inside the cohort's IQR (-2.03% to +3.35%). The cohort's central tendency held — neither the bull nor bear feature bucket fired hard enough to push the reaction into the tails.
- n=254, 5d median +0.53%, IQR [-2.03%, +3.35%]
- Conformal bucket boundaries: p10 -4.26% / p90 +5.83%
- Top 5d feature: macro_state=bullish (negative direction, importance 1.72)
- Actual reaction: +0.41%; verdict: central tendency hold
The Calibration Lesson
For ABNB, the calibration verdict is: central tendency hold. The cohort's structured features (macro_state=bullish dominant) provided the directional read; the realized magnitude lands relative to that read at the bucket described above. Agent systems should retrieve the post-print cohort 24-48 hours after the close — the chart shape will have stabilized, the feature attribution sharpens, and the forward 5-10 day continuation distribution becomes actionable.
