Rolf Banz originally trained as an engineer at the ETH in Zurich. Later, he obtained an MBA and PhD at the Graduate School of Business of the University of Chicago.
His dissertation was on the pricing of small companies in the US market – what became known as the small firm effect. After a number of years teaching in business schools in Canada, the US and France, he started, with his wife and American partners, an investment boutique in London that concentrated on small cap investment.
In 1991, the firm was sold to Alliance Capital and Rolf became head of its London office, responsible for all international equity investment activities.
Then, for fifteen years, he was with Pictet Asset Management in a number of senior positions. After his retirement, he now consults for a number of institutional investors and families.
