Who is Roger Gibson?
As the name suggests, the Roger Gibson 5 Asset Portfolio was created by financial adviser Roger Gibson. He also created the Talmud Portfolio.
In a 1998 paper titled Asset Allocation and the Rewards of Multiple-Asset-Class Investing, Gibson drew from the foundational work of Harry Markowitz, the father of modern portfolio theory, to show how a combination of volatile, uncorrelated assets could produce higher returns and, more importantly, higher risk-adjusted returns, with less volatility than the average of those assets held in isolation.
This of course is the same premise upon which many portfolios like the All Weather Portfolio are built. Markowitz proposed the idea of the efficient frontier for portfolios, along which we can assess expected returns for any given level of volatility, or expected volatility for any given expected return.

Roger Gibson 5 Asset Portfolio Performance vs. the S&P 500
With my commodities data only going back to 2007, here’s the 5 Asset Portfolio’s performance vs. an S&P 500 index fund through 2019:
With international stocks and commodities suffering in recent years, the 5 Asset Portfolio has delivered lower general and risk-adjusted returns (Sharpe), with volatility only slightly lower than the S&P 500. I very much question the high allocations to commodities and REITs. I don’t think their diversification benefits warrant an allocation of 40% of the total portfolio. It’s almost diversification for the sake of diversification with unnecessarily equivalent allocations compared to the stocks holdings.
