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.
Transactions: historical flow observations only. They are not used to reconstruct current ownership and are shown only for companies where recent transaction history is currently published.
Not included here: a claim of total insider ownership, total personal wealth, institutional 13F ownership, or an investment recommendation.
