We Asked Fidelity's Ex-President What Made Peter Lynch Great — and Where Private Credit Risk Hides
Former Fidelity president and MFS chairman Bob Pozen joins Excess Returns to discuss retirement investing, the risks in private credit, and why he favors a 90% stock and 10% cash portfolio for investors who can cover their living expenses without selling stocks. Drawing on decades in asset management, he shares lessons from Peter Lynch and Warren Buffett, explains why index funds are difficult to beat, and challenges conventional thinking about bonds, Social Security, and corporate earnings reporting.
