Chapter 01
Selection — the cost of admitting a name to the portfolio.
Every position begins with a two-page memo written by a partner, not an analyst. The memo must answer three questions in plain English: what does this business sell, why does it keep its customers, and what would have to be true for the next ten years to vindicate the price we are paying today. If a junior member of the team cannot defend the memo against a senior partner in a thirty-minute argument, the name does not enter the portfolio. We carry at most seven names at any time. A name is therefore not added; it replaces.
