A Gallery of Rogues: 4 Traders Who Lost Billions

Kweku Adoboli, UBS

Zurich-based banking giant UBS announced in September that a rogue trader caused massive losses that ultimately totaled $2.3 billion. London police arrested 31-year-old Adoboli, a trader at the bank's exchange-traded fund desk. UBS CEO Oswald Grübel resigned later that month. Adoboli is due to enter a plea later this month. He faces up to 10 years in prison, based on sentencing guidelines.
