Transaction date versus filing date

By Outfox Editorial · Reviewed September 2, 2026

Quick answer

The transaction date is when the reported purchase, sale, or other ownership change occurred. The filing date is when the disclosure was submitted or made public. The time between them is disclosure lag, and it determines how stale a public signal may be.

Key takeaways

  • Always compare the transaction date with the filing date before interpreting a disclosed position.
  • Form 4 activity is generally reported much sooner than congressional transactions or quarterly 13F holdings.
  • A current filing can describe an event that occurred weeks—or, for quarter-end holdings, months—earlier.
  • Outfox should label freshness by source instead of presenting all records as equally current.

Why does the difference matter?

A headline published on the filing date can sound current even when the underlying activity is not. Showing both dates prevents a delayed disclosure from being mistaken for a real-time signal.

Outfox will calculate disclosure lag in calendar days and retain source-specific explanations. We will never substitute the filing date for an unknown transaction date.

Different filings have different clocks

Form 4 is generally due within two business days after the transaction. For covered House filers, qualifying transactions over $1,000 generally must be reported on a PTR by the earlier of 30 days after the filer becomes aware of the transaction or 45 days after the transaction. Form 13F is a quarter-end holdings snapshot that can be filed up to 45 days after the end of a calendar quarter.

The Outfox freshness ladder

Outfox will show the source, as-of date, filing date, transaction date when available, and calculated lag. Comparisons across Congress, insiders, and institutions will preserve those differences instead of pretending every signal arrived at the same time.

What this information cannot tell you

  • A filing date does not reveal whether the position is still held when a reader sees it.
  • Amendments can add or correct information after the original disclosure.
  • Market-price movement between the transaction and filing dates can materially change the opportunity and risk.
