Activist Filer History

API TraderAPI QuantAPI Developer

The full 13D/G filing history of one reporting person, newest first, across every company they have filed on.

Address the filer by their SEC CIK (exact - as returned by the activist filings feed) or by name, in which case the most active filer whose name contains the query is selected.

Available Data Points:

  • Company / Exchange / Ticker: The subject company of the filing.
  • Filed Date / Event Date: When the filing was made, and the transaction date it discloses.
  • Filing Type: 13D, 13G, amendments (/A), and 13G>13D for a passive holder turning activist.
  • Filer Name / Filer CIK: The reporting person and their stable SEC identifier.
  • Filer Image URL: The filer's portrait or logo, hosted on the ORTEX CDN (empty when none is available).
  • Percent Of Class: The stake disclosed in the filing.
  • Percent Change: The change versus the same filer's prior filing on the same company.
  • Shares Owned: Aggregate shares beneficially owned.
  • SEC URL: The filing's index page on sec.gov.

Rows are the filer's complete history: new stakes, additions, trims and exits over time, with percentChange computed against their prior filing on each company.

Try it out! You can test the API with the trial key TEST. Simply include it in your request headers; either here, or add the header "Ortex-Api-Key": "TEST" to your http request.

Trial key restrictions: Trial keys may be limited to a specific date range and set of regions. Requests outside the allowed regions or entirely outside the allowed date range are rejected; a date window that partially overlaps the allowed range is trimmed to it, reported in meta.restriction.
