    The Comeback Kid of Wall Street: Bill Ackman

    He turned $27 million into $2.6 billion in under a month, and lost more than $4 billion on a single stock. In this solo episode we follow Bill Ackman from the mentors who shaped him and a first fund that closed, to the six-year bet against MBIA, activist fights at Wendy's, Target, J.C. Penney and Canadian Pacific, and the dark years of Herbalife and Valeant. At his lowest point, with his fund down 30%, rivals circling and his marriage ending, he leaned on one simple rule: make a little progress every day. Then came the COVID hedge and his 2026 bet to build the next Berkshire Hathaway. A story about investing, and about how to keep going when everything falls apart.
