Whale Holdings from 13F, EDINET, and CSRC

How SurgeFlow tracks institutional holdings across US, Japan, and China disclosure systems.

Category: Whales

Disclosure systems differ

US 13F filings, Japan EDINET large-shareholder filings, and China CSRC fund disclosures have different timing, fields, and reliability constraints. SurgeFlow labels these differences instead of pretending they are identical.

Signal states

Whale signals move through draft, restricted, and publish-tested states. A signal can be visible in the UI before it is allowed as primary evidence for agent selection.

Use in research

Whale evidence is best used as context for accumulation, crowding, and institutional sponsorship. It should not override valuation, liquidity, or risk controls.
