Most retirement portfolios force a tradeoff: accept lower growth for safety, or chase higher returns and live with deeper losses. This book argues there is a better way. The Sleep-Well portfolio is a simple 3-ETF strategy designed to balance growth, liquidity, and downside defense. In the book’s backtesting, it delivered a 13.41% CAGR with a maximum drawdown of -8.28%, versus 9.42% and -20.16% for a traditional 60/40 portfolio, 9.30% and -15.93% for the Permanent Portfolio, and 5.67% and -21.03% for the All Seasons Portfolio. The result is a portfolio that was not only simpler, but also stronger in both return and drawdown control. This book explains the structure behind those results and shows why a more focused approach may offer retirees a more durable and manageable alternative to traditional portfolio models.
