Billionaire Leon Cooperman Says Investors Are Acting Like ‘Pavlov’s Dog’ — Reveals 2 New Stock Picks
Leon Cooperman expressed a negative market view due to rising fiscal deficit and debt, citing Warren Buffett's analogy of investors acting like 'Pavlov's dogs'. Omega Advisors, managed by Cooperman, revealed new positions in Amrize AG (AMRZ) and GPGI (GPGI). Amrize reported Q2 revenue growth but missed EBITDA expectations, with RBC downgrading the stock to underperform. Management expects pricing to align with costs by Q4.
