Regulatory regimes and filing thresholds
Prior Moves tracks shareholding disclosures across eight regulatory regimes. Each market defines who must file, when, what threshold triggers reporting, and what the public record must contain. Below are the filing requirements, the public registers where disclosures appear, and how each regime feeds the Prior Moves rankings.
| Regime | Jurisdiction | Threshold |
|---|---|---|
| Form 13F/13D | United States | 5% |
| TR-1 Notification | United Kingdom | 3% |
| EU Transparency Directive | European Union | 3% |
| Disclosure of Interests | Hong Kong | 5% |
| Large Shareholding (大量保有) | Japan | 5% |
| 5 Per Cent Rule | South Korea | 5% |
| SEDI Insider Filing | Canada | insider filings |
| Substantial Shareholder Notice | Australia | 5% |
Why this matters
A 13F shows what an investor held weeks ago. The forms above show who disclosed a holding and when. By understanding the reporting deadlines and thresholds of each regime, you can calibrate how fresh a public disclosure is and what behaviour it actually signals. A position reported under one regime may have been opened long before the filing arrived; under another, the deadline is tight enough to track the trade closer to real time.
