1. Portfolio Overview

Four Tree Island Advisory LLC has reported a significant expansion in assets under management (AUM), with the total portfolio value surging by 260.8% from $50.21M in the previous quarter to $181.17M as of December 31, 2025.

The portfolio is relatively concentrated, holding 23 distinct securities. The manager employs a high-conviction strategy, with the top 10 positions accounting for approximately 88.6% of the total portfolio value.

This suggests the firm favors a focused approach over broad diversification, seeking alpha through specific stock selection rather than market replication.
