The Education of a Value Investor; checklist investing, environment design

Guy Spier manages Aquamarine Fund, a value-oriented investment partnership based in Zurich. He chronicled his transformation from a Goldman Sachs-trained banker into a disciplined value investor in his 2014 memoir 'The Education of a Value Investor'. He is particularly associated with adopting process-driven checklists and physically relocating away from Wall Street to reduce cognitive biases in decision-making.
