The Trilogy of Portfolio Design
Effective portfolio design involves a multifaceted approach, centered around three key dimensions: size at purchase, size over time, and share of mind. Size at purchase establishes initial risk exposure and reflects an investor's conviction, with gradual position adjustments recommended for better average entry points. The second dimension, size over time, encourages allowing winning investments to grow while minimizing the impact of underperformers, as illustrated by the coffee can portfolio strategy which emphasizes holding high-quality stocks indefinitely. This passive approach helps to let top performers naturally dominate the portfolio, while still recognizing the need for deliberate rebalancing to manage concentration risk.
