Comprehensive Analysis of Luminus Management LLC (SEC 13F)
1. Portfolio Overview

The most defining feature of Luminus Management LLC’s Q3 2025 filing is a dramatic contraction in portfolio size. The total asset value plummeted by 81.7%, falling from approximately $341.10 million in the previous quarter to $62.47 million.

Despite the reduced capital base, the fund maintains a highly concentrated portfolio with only 13 holdings. The turnover was exceptionally high this quarter, driven by a massive reduction in a single position.

This structure suggests the manager is not seeking broad market exposure but is instead targeting specific turnaround situations or undervalued assets.

2. Key Holdings

The portfolio is currently dominated by deep-value or special situation plays in the industrial and materials sectors.
