# Get activist stakes

`GET /activist-ownership`

Get activist stakes (SEC Schedule 13D: holders of more than 5% of a class of shares with intent to influence control), one row per reporting person. Query by ticker (who holds activist stakes in this company) or by filer_cik (what stakes does this activist hold); provide exactly one of the two. By default each stake's current state is returned; set history=true for the full amendment chain. This endpoint is the activist-only view of /beneficial-ownership.

## Query parameters

- `ticker` string
- `filer_cik` string
- `history` boolean
- `filing_date` string, date
- `filing_date_gte` string, date
- `filing_date_lte` string, date
- `filing_date_gt` string, date
