Build YOUR Perfect Portfolio (w/ Cullen Roche) | #612

What It Covers

Cullen Roche explains his portfolio construction philosophy from his book "Your Perfect Portfolio," covering 20 investment strategies including 60/40, permanent portfolio, and his original defined duration approach that matches assets to specific time horizons.

Key Questions Answered

• •Saver vs Investor Mindset: Buying stocks on secondary markets means reallocating savings into instruments reflecting firm value, not directly funding investment. This framing prevents get-rich-quick thinking and promotes prudent, boring allocation decisions over speculative gambling behavior that trips up most investors.
• •Real Returns Reality: After subtracting 3% inflation, 0.5-1% fees, and 20-40% taxes, the headline 10% stock market return becomes significantly smaller in purchasing power terms. Roche presents all portfolio data inflation-adjusted to set realistic expectations about actual wealth accumulation versus paper gains.
• •Temporal Asset Allocation: Portfolio construction fundamentally solves time horizon problems—matching short-term cash needs with T-bills while aligning 15-20 year goals with equities. The 60/40 portfolio diversifies across different time horizons, not just asset classes, with bonds covering near-term and stocks funding distant consumption.
• •Defined Duration Methodology: Roche quantifies stock market time horizons by calculating expected returns against maximum drawdown risk. Technology stocks currently show 30+ year defined duration due to high valuations, while foreign value indexes measure closer to 15 years, enabling precise asset-liability matching in financial plans.
• •Forward Cap Portfolio: This strategy weights sectors by projected 2055 market capitalization rather than current values—allocating 40% to technology, plus overweights in emerging markets, healthcare, and decentralized systems. Backtesting shows this approach surprisingly beat US stock indexes despite higher risk and global diversification.
