About Seth Klarman

## Seth Klarman / Baupost Group — Institutional Portfolio Profile

**Seth Klarman** serves as the founder and portfolio manager of Baupost Group, a Boston-based private investment partnership widely recognized as one of the largest hedge funds in the United States. As of the Q1 2026 13F filing, Baupost Group's disclosed equity portfolio holds $5.1 billion in market value across 22 positions, reflecting a concentrated, selective approach to public equity exposure consistent with the firm's long-standing value-oriented investment philosophy.

The latest filing, submitted May 14, 2026, shows the portfolio anchored by five core positions representing 46.7% of total reported holdings. Amazon.com Inc. (AMZN) constitutes the largest single position at 12.7%, followed by Restaurant Brands International Inc. (QSR) at 11.7%, WESCO International Inc. (WCC) at 7.7%, Union Pacific Corp at 7.3%, and Elevance Health Inc. at 7.3%. The largest disclosed sector classification is "Unclassified," accounting for 39.3% of the portfolio, a weighting consistent with Baupost's documented history of holding positions in special situations, distressed instruments, and non-standard equity structures.

Quarter-over-quarter activity reflects meaningful portfolio reconstruction during the period. Baupost filed 6 new positions and exited 5, while increasing exposure across 9 existing holdings and reducing 4 others. The combination of new entries and simultaneous exits across 11 positions in a single quarter represents notable turnover relative to the portfolio's total of 22 disclosed holdings, indicating active repositioning within the reported period.

Why this matters
Why a new position matters

Opening a new position can suggest the manager sees value or a thesis worth committing capital to. It does not necessarily mean they are bullish on the broader market — concentrated managers add positions infrequently while quants may rotate constantly.

Why this matters
Why an increase matters

Adding to an existing position may indicate higher conviction, scaling into a thesis, or rebalancing toward a target weight. It does not necessarily mean the position is undervalued at the current price.

Why this matters
Why a reduction matters

Trimming a position may suggest portfolio rebalancing, profit-taking, or risk management. It does not necessarily mean the manager has turned bearish on the underlying company.

Why this matters
Why a full exit matters

Fully exiting a position can suggest that the manager's thesis has played out, was wrong, or that capital is being redeployed elsewhere. It does not mean the company is broken — exits are often as much about portfolio fit as about the security itself.
