Portfolio Overview

The filing for Gilead Sciences, Inc. (CIK: 0000882095) reveals a highly specialized investment portfolio totaling $1.65 billion as of September 30, 2025. This represents a significant appreciation in portfolio value, increasing by 29.0% from the $1.28 billion reported in the previous quarter. The portfolio is exceptionally concentrated, comprising only seven holdings. This lack of broad diversification indicates that the capital deployment is not intended for general mark...

The portfolio is heavily skewed towards its top three assets, which account for approximately 94.3% of the total value. The top two positions, Galapagos NV and Arcellx Inc (ACLX), are nearly equal in weight, comprising 35.05% and 33.41% of the portfolio respectively. This bar-bell structure suggests a focus on high-conviction assets rather than a balanced, diversified fund approach.
