build 9b2d1cd4 · data through 2026-07-21 · methodology v5
WHAT CHANGED- Since build 9b2d1cd4, ZEO added 0 filings, 0 accepted events, and 0 newly matured events.
- No issuer changed C6 state.
- Coverage weight unchanged.
- Retroactive edits: 0.
WHAT MATTERS- Evidence is concentrated: SU and PBA hold 35% of accepted events and 17.8% of lens weight.
- Form 4 coverage: 2/9 covered issuers — most covered Canadian issuers report insider trades through Canada's SEDI system, which is not yet ingested.
WHAT THE EVIDENCE SAYS- Peer-adjusted event performance is -0.4% at day +20 (95% CI [-2.0%, +1.2%], n=46) — status: DESCRIPTIVE.
WHAT REMAINS UNCERTAIN- Confidence intervals shown are naive: they assume independent events, while issuer clustering and overlapping windows make them optimistic. Clustered inference is scheduled and will be pre-committed before computation.
- C6 sign confirmation remains accruing; posture states are research classifications of evidence rarity, not directional calls.
INSPECT NEXTordered by trigger count — not an investment ranking
- CNQ — C6 posture elevated
102 filings → 84 prose → 81 candidates → 81 accepted → 76 deduped → 71 matured → 50 direction-eligible

What would change this conclusion
- If the effect stays near -0.4%, roughly 129 additional distinct issuers with events (~137 total clusters) would be needed before the clustered CI could exclude zero (1/√G approximation).
- A true effect smaller than the current MDE (2.2% at 80% power) cannot be detected at this sample size — absence of significance is not evidence of absence.
- SEDI ingestion could reveal an insider pattern not visible in the current Form 4 scope, changing the risk-side reading for MJDS issuers.
- If naive and clustered intervals diverge further as events accrue, issuer clustering — not the event effect — is doing the work; per-issuer decomposition becomes the priority.
