Noted value investor Guy Spier first gained public attention in 2007 when he and a partner paid just over $650,000 at a charity auction to have lunch with Warren Buffett. Spier launched his fund Aquamarine in 1997, following closely to Buffett’s principles, but closed it down in early 2026 and returned money to investors following a diagnosis of the brain cancer Glioblastoma. He tells Becky Quick how facing the end of his life taught him the true meaning of value.
