Comprehensive Analysis of SEC 13F Filing: Marathon Asset Management LP
1. Portfolio Overview

Marathon Asset Management LP’s filing for the period ending September 30, 2025, reveals a significant contraction in portfolio size and a substantial shift in asset allocation. The total portfolio value decreased by 30.8%, dropping from $44.14M to $30.54M. This reduction in Assets Under Management (AUM) is driven not merely by market performance but by aggressive deleveraging and positi...

The portfolio is currently highly concentrated, containing only 12 holdings. This indicates a high-conviction strategy where capital is deployed into a select set of ideas rather than broad diversification. The turnover rate for the quarter was exceptionally high; the manager completely exited 7 positions and initiated **2 new ones, representing a major restructuring of the fund's exposure. The largest single driver of the portfolio reduction was the liquidation of GrafTech International Ltd., which previously accounted for nearly 45% of the fund's total value.

2. Key Holdings

The current portfolio is dominated by a few large, idiosyncratic bets, with the top three positions comprising over 52% of the total value.
