Definition

Notice of proposed sale of restricted or control securities, filed by affiliates when they intend to sell under Rule 144. The ingestion schema already supports Form 144, but it is not part of the first product UI unless explicitly prioritized — sales under Form 144 are planned dispositions, not always executed trades.

Form 144 vs Form 4

Keyword focus: form 144 vs form 4

Form 144 is a notice of proposed sale, while Form 4 reports changes in beneficial ownership. That distinction matters: a Form 144 filing can indicate an intention to sell restricted or control securities, but it is not itself the executed sale row.

A completed insider sale normally appears on Form 4 with a transaction code such as S. Form 144 can be useful context, but it should not be counted as the same thing as an executed Form 4 sale.

  • Form 144: proposed sale notice under Rule 144 context.
  • Form 4: reported ownership change after a qualifying transaction.
  • Use Form 144 to understand planned-sale context, not completed trade volume.
  • Keep Form 144 pages separate from Form 4 transaction feeds.

How to read this term

Practical filing context for this specific glossary entry

Start with the filing type

The form number determines whether you are reading an initial holding, a change in ownership, an annual catch-up, or a proposed sale notice.

Use identifiers carefully

CIKs, accession numbers, and SEC URLs are durable references. They are safer than company names when matching across systems.

Do not mix surfaces

A Form 144 proposed sale is not the same thing as an executed Form 4 sale. Keep proposed-sale context separate from transaction rows.
