============================================================================
dbo.usp_sec_list_peers
============================================================================
List other companies in the same SIC code as a target CIK.
The target's SIC is resolved from its most recent filing (max filed).
Peers are listed with one row per distinct cik (deduped), showing the
latest name and filing date observed.
Parameters
----------
@cik target company (required)
@top max peers to return (default 100)
Notes
-----
* sec_fsnds has no index on sub.sic -- this is a scan. Sub is 820K
rows and fits in memory, so the scan is sub-second.
