Code P is not proof of a discretionary open-market buy. Code P includes open-market or private purchases. It is not, by itself, proof of an open-market discretionary trade. Read the footnotes.
Review checks & calculation notesDeduplication, amendments and limits
Before you act
0 repeated accession/row IDs removed; 0 conflicting IDs excluded.
Multiple reporting owners can describe one economic transaction. Do not treat filer counts or summed shares as unique economic demand.
No market prices, subsequent returns, or performance rankings are inferred.
Cluster-buy, notable-purchase, and dollar-volume figures are plain math on your imported rows, not a proprietary score or sentiment signal.
P: purchase; S: sale; A: grant or award; M: exercise or conversion; F: tax or exercise-price withholding; G: gift. Each code still requires filing context.
Amendments are retained for inspection, not treated as new discretionary transactions. Accession number plus explicit transaction ID is the deduplication key.
Entity identity and ownership relationships must be reviewed against SEC identifiers. Similar names are not automatically merged.
Cluster-buy detection uses the maximum count of distinct filer CIKs buying the same ticker within the chosen rolling window; it does not infer coordination.
Exercise/sale reconciliation only pairs rows with a matching filer, ticker, and trade date; it does not track holdings across multiple days.

How to read this casebookMethod, examples and source references
Plain arithmetic. Visible assumptions.
Import normalized ownership transactions using the CSV template. Duplicate accession/transaction IDs are removed; conflicting copies are excluded. Filters then select the records for analysis.
The priced purchase subtotal includes only non-derivative, non-amended P rows outside investment-fund activity with a known price. Cluster buys count distinct filer CIKs in your rolling date window. Notable purchases use your value threshold. These figures do not establish intent or predict returns.
In the fictional walkthrough, three priced purchases of $30,000, $48,000 and $26,000 produce a $104,000 subtotal. A fourth eligible purchase has an unknown price and is not assigned a zero value. Multiple reporting owners can describe the same economic transaction.
A reported purchase is not an investment recommendation. Form 4 interpretation can depend on footnotes and ownership relationships.
