Investment philosophy

Guy Spier is, in his own words, a ‘fervent Warren Buffett disciple’ and follows Buffett’s approach to value investing and asset allocation. His approach is primarily global, long-term and value-focused.

A unique characteristic of Spier’s portfolio is how few changes occur quarter to quarter. It can often take six months or even years before he makes a deal. At the same time, he is very concentrated with typically 10-20 positions in total.
