A chimpanzee was once ranked as the 22nd most successful money manager in the US. In 2009 Raven the chimpanzee was listed in the Guinness World Records book as the most successful chimpanzee on Wall Street. Raven chose her stocks by throwing darts at a board with 133 different Internet companies listed on it and achieved a 233% gain in 1999. She was so good that she performed better than 6,000 professional Wall Street brokers!
