Paul Isaac - Arbiter Partners Capital Management Investment Strategy & Portfolio Analysis

How Arbiter Partners Capital Management allocates capital, manages risk, and constructs its portfolio — based on SEC 13F filings.

According to the SEC 13F filed on Sep 15, 2026, Paul Isaac's Arbiter Partners Capital Management portfolio reflects a concentrated approach across 34 reported 13F positions as of quarter-end Jun 30, 2026. Portfolio returns are primarily driven by a small set of high-conviction positions such as GRAIL,, Greif, Inc., and Corebridge Financial, with the top five holdings accounting for approximately 66% of total exposure and GRAIL, alone contributing ~41%. While the portfolio includes 34 positions, economic outcomes are highly concentrated in a narrow set of healthcare and financials names, indicating a meaningful divergence between structural diversification and return concentration. Exposure to high-growth and technology-oriented segments remains limited relative to peers, with performance instead anchored in durable, cash-generating businesses across healthcare, financials, and consumer discretionary. The portfolio exhibits extremely low turnover, reinforcing a patient, conviction-led investment approach. Distinctive traits include Long-Term Holder, Moderately Concentrated, Economically Concentrated.
