Leopold Aschenbrenner - Situational Awareness Partners Investment Strategy & Portfolio Analysis

How Situational Awareness Partners allocates capital, manages risk, and constructs its portfolio — based on SEC 13F filings.

According to the SEC 13F filed on Aug 14, 2026, Leopold Aschenbrenner's Situational Awareness Partners portfolio reflects a highly concentrated, high-conviction, opportunistic approach across 16 reported 13F positions as of quarter-end Jun 30, 2026. Portfolio returns are primarily driven by a small set of thematic positions in energy and industrial infrastructure names, with the top five holdings accounting for approximately 86% of total exposure and SanDisk alone contributing ~31%. While the portfolio includes 16 positions, economic outcomes are highly concentrated in a narrow set of energy and industrial infrastructure names, indicating a meaningful divergence between structural diversification and return concentration. Exposure to high-growth and technology-oriented segments is elevated relative to peers, with performance anchored in growth-oriented names across technology, unknown, and industrials. The portfolio maintains moderate turnover, consistent with periodic rebalancing rather than a fully static book. Distinctive traits include Moderate Turnover, Highly Concentrated, Economically Concentrated.
