In 2000 a young PhD in mathematics approached me about a job before eventually landing at a European bank in research. In 2004 he started proprietary trading, where traders bet with the bank’s money. Pay was 15% of the profits. In 2005 he bought obscure and high-yielding corporate bonds, which generated profits of $40 million. He took home $6 million. In 2006 he made $80 million and took home $12 million. In 2007 the world turned and the group was disbanded as losses mounted. He was dismissed, and his trades eventually lost the firm close to $300 million.
What was his PhD thesis about? Game theory, or using math to find the optimal solution to complex systems.
Late last year he sent me an email. “Chris, why are you still working?”
