Portfolio Overview

The Washington State Investment Board (WSIB) presents a highly concentrated and specialized portfolio in this filing, with a total market value of $289.69 million as of September 30, 2025. The portfolio is exceptionally narrow, comprising only two holdings, which indicates a high-conviction strategy rather than a broad diversification approach. Over the quarter, the total portfolio value increased by 12.9%, rising from $256.49 million. This growth appears to be a function...

Key Holdings

The portfolio is dominated by FTAI Aviation Ltd (FTAI), which constitutes 82.26% of the total value, or approximately $238.30 million. Despite being the largest position, the board reduced its stake in FTAI by 10.6% during the quarter, selling off roughly $54.53 million in value. This reduction leaves the fund with 1.43 million shares. The second holding, FTAI Infrastructure Inc (FIP), accounts for the remaining 17.74% ($51.39 million), comprising 11.79 million shares. This position remained unchanged during the quarter. The heavy weighting toward FTAI Aviation implies that the fund's performance is inextricably linked to the specific fortunes of that single entity, representing a significant idiosyncratic risk profile.
