About Coordinated Trading Detection
What This Shows
This page identifies instances where 3 or more institutional investors ("whales") entered the same stock within the same calendar month. Patterns with 5 or more whales are flagged as potentially suspicious.
Possible Explanations
- • Analyst Upgrades: Brokers issuing buy recommendations
- • Corporate Events: Takeover bids, strategic announcements, or earnings surprises
- • Shared Research: Multiple funds accessing the same research or data
- • Index Rebalancing: Passive funds adjusting holdings due to index changes
- • Coordinated Action: Potentially concerning patterns requiring investigation
Data sourced from NZX substantial shareholder disclosures and director share transaction records. Performance calculated from entry price to latest available price or exit price.
