Risk parity tradeoffs

In this episode of Excess Returns, we sit down with Cullen Roche to discuss his new book Your Perfect Portfolio and the deeper principles behind building a portfolio that actually fits your life. Rather than starting with asset allocation models or return forecasts, Cullen reframes investing around risk, time horizons, and lifetime consumption. We explore how to think about stocks, bonds, factor investing, international diversification, private assets, inflation hedges, and more through the lens of financial planning and asset liability matching. This is a practical, wide ranging conversation about portfolio construction, behavioral risk, and how investors can align their investments with real world goals.

Main topics covered:

• Why you are a saver, not an investor, and why that distinction matters

• Defining risk as uncertainty of lifetime consumption

• The temporal conundrum and matching investments to time horizons

• Human capital as your most important asset and how it impacts portfolio risk

• The pros and cons of a 100 percent stock allocation

• Rethinking the 60 40 portfolio after inflation and rising rates

• International diversification and valuation differences between US and global markets

• Factor investing as a time horizon tool rather than an alpha strategy

• The forward cap portfolio and skating to where the market cap puck is going

• Inflation protection strategies including stocks, TIPS, gold, and the permanent portfolio

• Risk parity and the tradeoff between diversification and return

• Countercyclical rebalancing and managing behavioral risk

• Private equity, venture capital, and the illiquidity premium

• Defined duration investing and asset liability matching for individual investors

• The real impact of inflation, taxes, and fees on long term returns
