Christopher Bloomstran - Semper Augustus Investments Group Investment Strategy & Portfolio Analysis

How Semper Augustus Investments Group allocates capital, manages risk, and constructs its portfolio — based on SEC 13F filings.

As of Mar 31, 2026, Christopher Bloomstran's Semper Augustus Investments Group portfolio reflects a concentrated approach across 43 reported 13F positions. Portfolio returns are primarily driven by a small set of mega-cap compounders, with the top five holdings accounting for approximately 49% of total exposure and Berkshire Hathaway Inc. New alone contributing ~15%. While the portfolio includes 43 positions, economic outcomes are highly concentrated in a narrow set of large-cap financial and consumer defensive names. Exposure to high-growth and technology-oriented segments remains limited relative to peers, with performance instead anchored in durable, cash-generating businesses across financials, basic materials, and consumer staples. The portfolio exhibits low turnover, consistent with a buy-and-hold posture held through multiple reporting cycles. Distinctive traits include Long-Term Holder, Structurally Diversified.
