Kahn Brothers Advisors

Thomas Kahn, the son of founder Irving Kahn, serves as president and is the lead decision-maker. Irving Kahn, who died in 2015 at 109, managed the portfolio well past his hundredth year. The firm runs a concentrated, research-intensive process where a small team analyzes companies against strict value criteria.

No. Kahn Brothers Advisors is a registered investment adviser managing separate accounts for external clients — high-net-worth individuals and institutions. It is not a family office, though it is closely held by the Kahn family. The firm does not manage a single family's operating-business wealth.

The firm follows classic Benjamin Graham value investing. It targets securities trading below intrinsic value, emphasizing low price-to-book ratios and margin of safety. Irving Kahn studied under Graham at Columbia and served as his teaching assistant, and that intellectual lineage remains the firm's core identity.

Public filings show a portfolio of 30 to 50 equity positions, with significant weight concentrated in the top 10 holdings. Sectors historically include financial services, healthcare, energy, and consumer staples. The firm holds positions for years or decades, ignoring short-term market volatility.

The firm does not publicly disclose total AUM. Its quarterly 13F filing captures only US-listed equities, which have historically ranged between $500 million and $1 billion in market value. This excludes bonds, cash, non-US securities, and any private holdings.
