ol_13f_filer_analytics
shallowcom.oxfordledge/oxford-ledge · Verify this server
Institutional-filer behavior derived purely from 13F holdings: concentration (top-N %, normalized HHI), turnover, and persistence (long-term holder vs fast money) for one filer. Pass a NUMERIC CIK (a ticker will not resolve here; ol_13f_filer_search finds it). Returns {summary, fund, quarter, n_positions, reported_long_equity_value, analytics}. The denominator is the filer's REPORTED 13F long-equity value, explicitly NOT AUM. NO position list -- use get_13f_holdings. A filer with one stored quarter gets no fabricated turnover rate; an unreachable store is REFUSED (DATA_UNAVAILABLE). Source: SEC EDGAR 13F-HR (public domain; Oxford Ledge derived); FREE. Caveats ride the response's tool_notes.
