Leon Cooperman is a well-known billionaire hedge fund manager, and although he does manage money on behalf of a few clients, the bulk of his hedge fund's assets are his own money.

Cooperman started his investment career at Goldman Sachs, where he spent 25 years in increasing leadership roles, including a stretch as chairman and CEO of Goldman Sachs Asset Management. Impressively, he didn't start his private investment partnership, Omega Advisors, until retiring from Goldman Sachs in 1991.

Fast-forward to 2025, and the 81-year-old Cooperman now manages over $3 billion. His latest SEC filings show 47 different stocks.

When it comes to the five stocks on the list, here's a one-sentence explanation of what each one does:

  • Cooper Group is one of the largest mortgage servicers in the home loan industry.
  • Energy Transfer is a natural gas transportation and energy storage partnership with a 6.8% dividend yield and a $65 billion market capitalization.
  • Vertiv provides power, cooling, and IT infrastructure services.
  • Apollo Global Manager is an alternative asset manager with over half a trillion dollars under management.
  • WillScot Mobile Moni provides mobile storage solutions and modular buildings, mainly for businesses.

Perhaps the biggest takeaway is that Cooperman's portfolio certainly isn't full of the typical stocks you'll find at the top of many billionaires' portfolio. He only owns one of the "Magnificent Seven" stocks, Alphabet, and there are surprisingly few stocks throughout the portfolio that could be considered household names.
