Warren an enthusiastic follower of Graham, he disagreed with his teacher about the need to buy so many stocks. He had cast his lot with one stock: “Ben would always tell me GEICO was too high. By his standards, it wasn’t the right kind of stock to buy. Still, by the end of 1951, I had three-quarters of my net worth or close to it invested in GEICO.” And yet Warren “worshipped” his teacher, even though he had strayed so far from one of Graham’s ideas.
