Reporting-owner research graph

These relationships are joined only when the same single SEC reporting-owner CIK appears unambiguously across the publication-authorized company ownership universe. Name similarity is never used to create a relationship.

This graph is bounded to the company ownership relationships currently published by Grizzly Bulls. It is not a complete employment, board, ownership, portfolio, or wealth history, and a missing relationship does not establish that none exists.

SEC transaction evidence ledger

Each row preserves the reviewed SEC transaction evidence, including the effective-date basis, amendment state, reported post-transaction position when present, and a separately published current covered owner/security position when one can be matched uniquely. Reported price is shown when present. The lab does not calculate gross proceeds, reconstruct balances between filings, or treat historical transactions as current wealth.

A reported post-transaction position is the balance stated in that historical transaction filing. A current covered position is a separate latest owner/security observation and may reflect later filings or activity. They are shown side by side as evidence points, not as a reconstructed continuous ledger.

Coverage and interpretation

Current holdings: direct positions that the reviewed ownership data can trace to an exact reporting owner, legal security, and current-basis quantity.

Current value: the existing published company-position valuation. This lab does not recalculate security values or infer missing positions.

Transaction evidence: historical flow observations with filing provenance. Reported post-transaction balances and current covered positions are separate evidence points; the lab does not interpolate ownership between them.

Reporting-owner graph: exact reporting-owner CIK relationships across the published company universe. It does not merge people by name or create a complete personal history.

Not included here: a claim of total insider ownership, total personal wealth, institutional 13F ownership, a transaction-value estimate, an insider sentiment score, or an investment recommendation.

Published ownership evidence chronology

This sequence orders only the ownership evidence already published by Grizzly Bulls for the exact reporting-owner relationships above. Transaction rows are ordered by filing date while preserving the separate economic effective date and its basis. Current covered snapshots remain separate latest observations.

The chronology does not interpolate ownership between entries, infer missing activity, pair an amended filing with an assumed parent, infer amendment supersession, or treat a current covered snapshot as proof of continuous ownership.

These handoffs preserve the exact company identities already represented in the reporting-owner graph. My Stocks keeps a listed company in your existing research lists. Research Inbox is a separate company-change update workflow.

Saving a company to My Stocks never enables updates, and opening Research Inbox never subscribes you automatically. Each update remains an explicit company-level opt-in under the existing Research Inbox consent flow.

These are company-level continuation paths, not reporting-owner subscriptions. Saving or watching one company does not automatically save or watch the other companies connected to the same reporting owner, and it does not create an owner-level alert.
