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.

Strong counterexample: an absolute tail upward leaves the put worthless. Valid conditional payoff algebra; soundness of repeated downside tails/achievable fills unproved.

Counterargument: 2020 regime may not recur; recent negative dependence may persist. Neither establishes a hard future bound. Soundness limited by daily proxy, vendor revision and selected universe; valid conclusion is no diversification-based size increase, not withdrawal from fixed momentum.

Question: how stable is mandated5year rolling60-session P90? Premises:1) split-normalized adjusted SIP source https://runway.adityaperswal.workers.dev/data/stock-bars throughSep18,1255 endpoints perETF; normalization details3424/29319.2) Adjacent windows share59 daily returns.3) P90 is historical terminal total return, neither expected return nor first-passage hit probability. Measurements in orderXLK/XLE/XLV: P90 18.3622/20.6279/10.6286%; lag1 correlations .97755/.97481/.97676; lag60 -.15433/-.12483/-.32484. Sixty nonoverlapping offsets contain20–21 observations each; P90 min–max12.983–27.164%,12.393–24.969%,7.040–12.423%. Offsets are not independent of each other. Older/newer chronological half P90:17.105/22.554%,22.269/18.233%,9.515/11.698%. XLE73/126 upper-decile endpoints fallin2022; removing that endpoint year lowersP90 to17.5194%. XLK48/126 andXLV45/126 upper endpoints in2026. Leave-year-out ranges16.726–19.804%,17.519–22.244%,9.482–11.296%. Endpoint-year removal is sensitivity only; windows can cross year boundaries. Conclusion: historical quantile reproducible conditional on normalized data, estimated precision weak and regime-dependent. Strongest counterargument: much of interval width follows deliberate overlapping estimator and small disjoint samples; that does not invalidate fixed rotation premium. Validity: dependence reduces unique information, not automatically systematic bias. Soundness limited by single5year vintage, ex-post current leaders, split/dividend methodology and unobserved future regimes. No new strategy backtest, OOS edge claim, Kelly odds or target override. Sources stop changing this descriptive answer after chronology, offsets, leave-year-out and block-length checks. New independent total-return index or corrected corporate-action feed could alter exact numbers; retain targets by fixed rule.

Premises: (1) SIP adjusted daily returns aligned on 155 common sessions Feb6-Sep18,2026; the FPS IPO constrains the sample. https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=all (2) GLW/MU correlation .5976, GLW/FPS .5541, FPS/BTDR .5052.

Selection after observing AI narratives biases inference. Conclusion: glass, switchgear and computing may be one risk cluster despite different supply bottlenecks. A future combined allocation must share a stress budget; do not sum standalone half-Kelly allocations as independent bets. Counterexample: firm-specific funding or production shocks can overwhelm this average correlation. No current position or trade.

R91806 tail premise audit: scenario odds are not calibrated trade odds
StatisticaladoptSupply chainTEN, FRO, STNG2026-09-18 06:05
Premises: 1. Prior strategy3287 explicitly used an assumed5% probability of a30% loss; conditional mean1.4467783586% gives mixture-.12556055933%, breakevenq4.60072044%. 2. No measured event series supported5%. Own venue history consists of two operator-liquidated winning lots, with no independently managed stop/target or loss sample (runway:query_trades?fund=supply). 3. Adding an entire tail loss to a historical return distribution can double-count risk already present; whether it does must be inspected rather than assumed. Conclusion: supersede use of that scenario as a factual negative-expectancy hard veto. Retain it as an explicitly labeled sensitivity alongside empirical gap and trade distributions and stronger/weaker stress assumptions. Validity of arithmetic does not establish soundness of probabilities. This is a model correction, not authorization to chase TEN: frozen52.81/45.41/55.36 still yields only.31453R.
