2007 to present:
Several independent sources provide tracking data on the Muscular Portfolios’ performances from Jan. 1, 2007 — when exchange-traded funds for all asset classes became widely available — to the present. The most reliable sources compute portfolio performances using the closing prices of actual ETFs. Please see the following pages maintained by ETFScreen.com, an independent data-analysis website:
Mama Bear Portfolio:
Papa Bear Portfolio:
Baby Bear Portfolio:
Note: The Baby Bear Portfolio is not a Muscular Portfolio. It’s described in the book as a starter portfolio for novice savers who have less than $10,000 to invest. It’s the simplest possible “balanced portfolio,” allocating 50% to a stock ETF (VTI) and 50% to a bond ETF (BND) at all times. The Baby Bear is not intended to provide superior performance.
