What's In Leon Cooperman's $3 Billion Portfolio? His 5 Cornerstone Holdings Revealed

Leon Cooperman, the 81-year-old hedge fund pioneer, is no stranger to wealth creation. Having built Omega Advisors into a powerhouse managing over $3 billion after leaving Goldman Sachs in 1991, Cooperman’s investment moves have long been a masterclass in contrarian thinking. But who is Leon Cooperman really? More importantly—what stocks does he actually own?

His latest SEC filings paint a fascinating picture: across 47 different stock positions, five holdings clearly dominate his portfolio. These aren’t your typical billionaire vanity plays.

The Big Five: Where Cooperman’s Billions Are Deployed

Based on current valuations, here’s how Cooperman’s capital breaks down:

Mr. Cooper Group (COOP) leads the charge at $275 million, giving the mortgage servicing giant a 4.47% stake—his single largest position by ownership percentage.

Energy Transfer (ET) sits second at $248 million (0.37% ownership), representing a meaningful bet on natural gas infrastructure. The partnership boasts a compelling 6.8% dividend yield and carries a $65 billion market cap.

Vertiv Holdings (VRT) commands $239 million (0.56% stake), focusing on data center power and cooling infrastructure—arguably one of the most overlooked sectors in Cooperman’s portfolio.

Apollo Global Management (APO) accounts for $229 million (0.25% position), tapping into the alternative asset management space where Apollo oversees over $500 billion.

Rounding out the top five is WillScot Mobile Mini Holdings (WSC) at $135 million (2.18% ownership), a play on modular buildings and mobile storage.

What This Portfolio Reveals About Cooperman

The striking takeaway? These holdings are anything but mainstream. Unlike many peers who stuff their portfolios with Magnificent Seven darlings, Cooperman owns just a single Big Tech stock—Alphabet—and largely avoids the household names crowding most billionaire watch lists.

His selections suggest a philosophy rooted in value and yield rather than momentum. Energy Transfer’s dividend appeal, Mr. Cooper Group’s mortgage servicing moat, and Vertiv’s infrastructure position each represent different angles on economic resilience.

The Cooperman Lesson for Regular Investors

Leon Cooperman’s stock picks remind us that billionaire wealth often compounds in unsexy sectors—mortgage services, pipeline infrastructure, and data center cooling. While most retail investors chase tech unicorns or meme stocks, institutional players like Cooperman hunt for overlooked value and steady income streams.

His willingness to hold significant stakes in mid-cap names (as evidenced by his 4.47% COOP position) also signals confidence that concentrated, contrarian bets can outpace diversified mediocrity.
