What this data is

Fund holdings (13F) for Baupost Group

Institutional managers with more than $100 million in US equities file a Form 13F within 45 days of each quarter end, listing every long position they held on the last day of the quarter. The site follows a fixed set of 30 managers and turns each filing into a table: the position, its value, its weight in the portfolio and how the share count changed from the previous quarter.

13F data is old by the time it's public, up to 135 days from the trade in the worst case. It won't tell you what a manager did yesterday. It tells you what they own, what they've been building for several quarters, and what they exited.

This page follows Baupost Group only. The full list and the cross-market view live on the Fund holdings (13F) hub.

How to read it

  • The change column is the story. A position built over three quarters is conviction; a position that appeared and vanished was a trade.
  • Portfolio weight beats dollar value for comparing managers of different sizes.
  • Treat every 13F number as weeks old and read it for structure, not timing.

Analysis of what the data shows, not advice. XOOMAR does not recommend buying, selling or holding anything.
