The traditional 60/40 portfolio—a mix of 60% stocks and 40% bonds—faces scrutiny for its ability to deliver consistent returns in today's volatile markets. Cullen Roche, founder of Discipline Funds, challenges this conventional wisdom on Bloomberg's Odd Lots podcast, urging investors to move beyond one-size-fits-all models.

Roche argues that portfolio design must be tailored to an individual's specific financial circumstances, risk tolerance, and time horizon. His new book, *Your Perfect Portfolio*, outlines a framework for integrating global asset classes, aiming to build resilience and optimize long-term growth rather than following a rigid, outdated template.

The discussion highlights a broader industry shift toward personalized investment strategies. As market correlations shift and inflation persists, advisors and individual investors alike are reassessing asset allocation. Roche's perspective suggests the future of portfolio construction lies in flexibility and a deeper understanding of personal financial goals.
