About Kahn Brothers Group

Kahn Brothers Group is a New York-based value-oriented investment firm founded by Irving Kahn — who studied under Benjamin Graham at Columbia and worked alongside him at Graham-Newman — and later continued by his sons Thomas and Alan. The firm runs a concentrated, long-only equity book in the classic Graham tradition: patient accumulation of statistically cheap or out-of-favor names, low turnover, and little appetite for macro positioning or derivatives. With 47 reported positions and top-5 holdings accounting for roughly 52% of the disclosed portfolio, the 13F is a reasonably complete picture of their activity; the book is equity-long with no known systematic use of shorts or options that would create material gaps between the filing and economic exposure. Readers should note that the backtest implied by the public filings has trailed SPY by roughly 2.4 percentage points annually over twelve years — a pattern consistent with deep-value strategies that have faced structural headwinds since 2010, and with a style that prioritizes capital preservation and absolute returns over benchmark-relative performance.

2026Q1 brief

Kahn Brothers' $560M deep-value book continued its idiosyncratic contrarian positioning, with the most notable move being a near-doubling of MBI (+100% to 2.2%) — a bond insurer trading well below book that few other investors will touch — alongside a 53% add to OGN (5.9%), the unloved Organon spinoff facing generic competition headwinds. The sole new position is Z (4.0%, Zillow), a surprising addition that suggests the Kahn team sees real estate tech as deeply discounted relative to a potential housing-cycle recovery. Offsetting these contrarian bets, BP was cut 40% and MRK trimmed 47%, the latter a notable exit from pharma defensives despite sector stress. The portfolio remains anchored by mega-cap value in C (16.9%) and distressed-adjacent BAYRY (13.3%), reflecting the firm's multi-decade time horizon. With NVDA fully exited and semis nowhere in sight, Kahn Brothers is as far from consensus positioning as any 13F filer in this cohort. Watch the Z position in 2026Q2 — any further add would suggest a more deliberate housing-recovery thesis is being constructed.
