Frank Armstrong Ideal Index Portfolio Performance Backtest vs. the S&P 500
With my REIT data only going back to 1994, here’s the Frank Armstrong Ideal Index Portfolio’s performance vs. an S&P 500 index fund through 2019:
With international stocks, small cap stocks, and the Value factor suffering recently, and with REITs taking a dive in the 2008 Global Financial Crisis, the Ideal Index Portfolio has delivered a lower risk-adjusted return (Sharpe) than the S&P 500 over this time period, with volatility only about 1/3 lower.
I believe the Value premium still exists. Clearly Armstrong does too. But that makes the dedicated inclusion of small-cap growth stocks questionable and confusing, as small-cap growth stocks have demonstrably not paid a risk premium historically. I can appreciate the dedicated inclusion of REITs and international stocks, but I also feel that a 30% allocation to a cash equivalent is far too conservative for my tastes, and won’t provide the diversification benefit that longer-duration bonds would.

Note that M1 Finance does not allow for fractions of 1% holdings on the first buy, so I’ve slightly adjusted the allocations.
