Solstein Capital, LLC

Solstein Capital provides discretionary investment management to private funds and separately managed accounts for individuals, high‑net‑worth clients, family offices and institutional accounts. The firm is the adviser to two private funds (Solstein Capital Partners, LP and Strike King LLC) and reported about $801.8 million in discretionary assets under management as of December 31, 2025.

The firm follows a value‑oriented, concentrated investment approach grounded in fundamental analysis and a stated practice of “complete and intense immersion” into prospective investments, with a typical public holding period of three to four years. Solstein emphasizes capital preservation while taking active, long‑term positions that may involve working with management and boards and holding through periods of market dislocation.

Distinctive aspects include its role as a private fund adviser and sponsor that charges performance‑based allocations for its flagship fund alongside a separately structured first‑loss vehicle (Strike King LLC) that shares profits rather than charging traditional management fees. The firm also retains an affiliate relationship with Longbow Trade Signals, LLC for trading research and operates with a small principal team relative to its AUM, a combination that the brochure identifies and for which it discloses specific side‑by‑side allocation and conflict‑mitigation policies.
