New York Mets owner and billionaire investor Steven A. Cohen is known for his speed, agility, and high-risk/high-reward investing approach, which has earned him a personal wealth of over £16.4 billion ($21 billion).
Cohen is the founder of the now-defunct SAC Capital Advisors, which is among the most successful hedge funds. The fund was charged with insider trading charges and repaid investors £1.4 billion ($1.8 billion) in penalties as Cohen faced a two-year ban on managing investor money.
