Rob Kirby, in a note written in 1984 (in the Journal of Portfolio Management), narrated an incident involving his client’s husband. The gentleman had purchased stocks recommended by Kirby in denominations of US$5000 each but, unlike Kirby, did not sell anything from the portfolio. This process (of buying when Kirby bought but not selling thereafter) led to enormous wealth creation over a period of about ten years. The wealth creation was mainly on account of one position transforming to a holding worth nearly $1m in Xerox. Impressed the power of this approach – of buying great companies and then letting them for ten years – Kirby coined the term “Coffee Can Portfolio”.
