Michael Platt is the Co-Founder, Chief Executive Officer, and Managing Director of BlueCrest Capital Management, one of Europe’s largest hedge fund firms. Platt splits BlueCrest’s assets between systematic strategies and discretionary trades. He believes in aggressive stop losses—he will cut traders’ allocations drastically if they lose as little as 3% of their capital, but will also lift allocations to winning trades. According to Sunday Times Rich List, he is Britain's wealthiest hedge fund manager, with an estimated net worth of $8 billion.
