R9251230 TH live tail gate: small-N P80 passes at the attainable ask
StatisticaladoptConvex tailTH2026-09-25 16:33
Premises: frozen, 21-session-separated liquid 52-week breakout sample has N4 because only four same-rule events are available; |move| median 27.3899%, P80 44.3186%. At the frozen $21.19 screen spot, Oct16 C27 at $0.18 has a 28.2681% strike-plus-premium hurdle, just above median, but $3.5811 P80 intrinsic equals 19.8951x premium and passes the alternative >=4x gate. Signed terminal intrinsic is positive in 2/4 events. Bootstrap P80 gate frequency 69.115% measures sampling instability, not win probability; P80 CI 13.3238%-48.6125%. Counterexample: one omitted regime or the secondary-offering flow can erase the apparent tail. Conclusion: one minimum contract is justified as a tail probe, not as proof of mispricing.

Target needs stock18.2977,10.0849% below20.35offer; moving to offer pays0. Conclusion old generic history does not estimate current downside odds. Validity: identical sample reproduces old gate; soundness fails transportability after binding deal. Bootstrap assumes iid old events and omits regime shift, is not probability band for current trade. Strongest objection: break risk can produce put tail despite deal; evidence that would change rejection is a matched announced-cash-deal study or documented material deterioration with honest expiry-specific odds.

StatisticalrejectConvex tailSFIX2026-09-19 04:07
Premises: (1) Ten issuer-dated AMC earnings March2024-June2026, each recorded individually observations29367–76; primary same-company/same-kind sample, no price-selected deletions. (2) SIP adjusted daily close immediately before release to next regular close measures total next-day response, not pure overnight news. (3) S=2.84 Sep18, Oct16 K2.5 put indicative ask .28. Calculation: median abs16.578014%, P80 abs31.413933%; put needs(2.84-2.5+.28)/2.84=21.830986%. P80 downward scenario intrinsic=max(2.5-2.84*(1-.31413933),0)=.552156, only1.971985x ask. Both mandate branches fail. Signed reactions have6negative/4positive; only1/10 exceeds .28 cost,2/10 exceeds .13; mean mapped intrinsic .116659 is NOT option fair value (excludes residual time value). At .13 hurdle16.549296% and P80 ratio4.247351 pass both gross criteria; median ceiling .130816, P80 ceiling .138039. After .02 assumed all-in friction/share, conservative hold-through ceiling .110816; these are limit research levels, not quotes/fills.
