Insider Cluster Watch
Methodology
The product is built around a narrow, auditable research workflow: parse eligible Form 4 purchase filings, materialize issuer event windows, score deterministic filing facts, and explain the result without recommendation language.
Launch Scope
Insider Cluster Watch focuses on SEC Form 4, transaction code P, common-stock, non-derivative insider purchases. Sale codes, derivatives, compensation grants, and broader ownership filings are intentionally outside the launch workflow.
Scoring Inputs
Scores use deterministic filing facts: distinct owner count, officer and director participation, reported purchase value, event-window concentration, security type, transaction code, and estimated market-cap materiality.
Freshness And Fair Access
Server-side ingest uses SEC access discipline, declared user agent headers, cooldown handling, and bounded filing retrieval. Public examples may include historical or backfilled windows; alert freshness is measured separately before growth claims are made.
Historical Outcomes
Outcome tables are descriptive close-to-close observations over defined horizons. They are not forecasts, expected-return estimates, or performance promises.
Research Boundary
The workflow explains filing facts and ranking reasons. It does not provide buy, sell, hold, portfolio, or allocation recommendations.
What This Does Not Do
Insider Cluster Watch does not estimate fair value, predict returns, recommend securities, or rank model portfolios. Users should always inspect source filings and perform independent diligence.
What the score means
Higher score
A higher score means the filing facts match more of the product's deterministic research criteria, such as multiple participating insiders, executive or director roles, larger reported purchase value, or stronger estimated materiality.
Lower score
A lower score can still be useful, but it usually means the event is narrower: fewer owners, smaller reported value, less role concentration, or less evidence of event-window clustering.
Why reasons are shown
Each event keeps the score reasons visible so a researcher can inspect the actual drivers instead of treating the score as a black box.
Why source links matter
The SEC XML filing link is part of the workflow because every event should be traceable back to public EDGAR source material before a user relies on it.
Research checks before interpreting an event
- 1. Confirm eligibility. Check that the transaction is a Form 4 transaction-code P, common-stock, non-derivative purchase.
- 2. Inspect the insiders. Review whether the owners are officers, directors, 10% owners, or other reporting owners.
- 3. Compare value and context. Reported purchase value can be meaningful or routine depending on issuer size, role, timing, and other public context.
- 4. Keep conclusions separate. The event page explains filing facts. Any investment conclusion requires independent diligence outside this product.
