His Investment Philosophy
Julian Robertson is a firm believer in the tenets of Value investing as mentioned by Graham in Security Analysis.
For Julian, the presence of a story is very crucial in all investment ideas. The story (thesis) has to be simple, logical and grounded with thorough research. He always asked his analysts to zero down their months of research of an idea into easy, understandable four sentence idea. If the ideas sounds good, then and only then, he will move forward and then till the point the story doesn't change, he would stick with the idea through thick and thin.
