Get ownership events

Returns major shareholder positions disclosed in SEC Schedule 13D/G filings. Each row represents one reporting person and security position in a filing, with the currently reported ownership, its change from the preceding filing when calculable, and a link to the official document; a joint filing can return multiple rows. Only the latest row for each company + shareholder + security sequence is returned. event_class is fixed at ownership and event_type at stake_change. For routine insider trades, use /insider-trades.
