The whale books.
Institutions running more than $100M must report their US equity books quarterly. The desk reads a curated set of concentrated discretionary filers straight from the EDGAR information tables: what they hold, what changed, and how stale the snapshot is.
Before you follow a filing
Treat every 13F as a delayed, partial snapshot.
These filings show reported holdings, not a manager's live portfolio or a complete record of every exposure.
- 01Snapshot
When was this portfolio measured?
A 13F reflects holdings at quarter end, not today. A filing can arrive up to 45 days after that date.
Check the reporting period - 02Coverage
What does the filing leave out?
It mainly covers reportable US long positions. It does not reveal a complete short, cash, or foreign portfolio.
Read the reporting limits - 03Change
What actually changed?
New, added, trimmed, and exited compare one quarter-end filing with the prior filing. They are not dated trade records.

Refresh exceptions

Failed refreshes never enter current aggregate statistics. A prior verified book can remain visible as last known good, with its failure code and verification date attached.No refresh exceptions in the loaded snapshot.
