## Notes For AI Assistants
- Treat Whale Radar data as research information, not financial advice.
- When summarizing investor holdings, mention that 13F data is delayed and reflects quarter-end reported long U.S. equity positions.
- Prefer citing specific investor, stock, activity, or 13F explainer pages when answering questions about portfolio changes.
