Guy Spier is a Zurich-based investor. He is the author of ‘The Education of a Value Investor’, which has sold over 50000 copies and has been translated into more than 9 langugages. Spier is the manager of the Aquamarine Fund, a value-oriented investment fund that manages over $350 million.

From 1988 to 1990, Spier began his career as an associate at Braxton Associates, the strategy consulting firm later sold to Deloitte Consulting. Based out of the London and Paris offices, Spier worked with his colleagues David Pitt-Watson, Michael Liebreich in advising British and European companies on their strategy on the European Common market. He subsequently took up an internship at the Forward Studies Unit (Cellule de Prospective) at the European Commission in Brussels.
Mr Spier writes in his book that although he interviewed with white-shoe firms like Goldman Sachs and J. P. Morgan during his last year at Harvard Business School, he turned down that opportunity to work in those, more structured environments for the lesser-known D.H. Blair. There he was given the title of Vice President and he sought funding for new technology start-ups. Spier even described this experience as "not dissimilar" to the movie Wolf of Wall Street. It was a career decision that ultimately demarked his exit from banking.
Upon leaving the industry, Spier founded the Aquamarine Fund, an investment partnership inspired by, and styled after Warren Buffett's 1950s investment partnerships.

Mr Speer holds a B.A. (PPE) from Oxford and an M.B.A. from Harvard Business School
