Bill Ackman
Activist Value
Ackman believes in owning a small number of high-quality businesses that generate strong free cash flow, have pricing power, and operate in industries with high barriers to entry. He focuses on businesses he can understand deeply, with predictable revenue streams and limited leverage. Unlike passive value investors, Ackman actively engages with management to unlock value.
