Context
How to read this filing
A Form 13F is a quarterly snapshot institutional managers with over $100M in US-listed assets must file within 45 days of quarter end. It shows long equity positions only: no short book, no cash, no non-US listings, no timing inside the quarter. Treat it as a delayed map of where the manager's conviction sat on the reporting date — not a live portfolio, and not a buy list.
