Leon G. Cooperman (born April 25, 1943) is a billionaire investor and hedge fund manager, best known as the chairman and CEO of Omega Advisors, a New York firm managing over $3.3 billion in assets—mostly his own wealth. Born to Polish-Jewish immigrants in the South Bronx, he was the first in his family to earn a college degree, graduating from Hunter College and later receiving an MBA from Columbia Business School. He spent 25 years at Goldman Sachs, where he was voted the number one portfolio strategist nine years in a row, before founding Omega in 1991 and eventually converting it to a family office after his retirement in 2016. In September 2016, the SEC charged him with insider trading related to 2010 trades in Atlas Pipeline Partners; he denied the allegations, but his firm settled for $4.9 million in May 2017 without admitting wrongdoing. As part of the settlement, Cooperman and Omega agreed to strict compliance monitoring—including access to their electronic communications and monthly certifications—until 2022, though he publicly called the process "totally abusive." He resides in Short Hills, New Jersey, with his wife Toby, with whom he has two sons and three grandchildren.
