The reasons for creating a Strategic Asset Allocation for retail investors based on allocating risk rather than on allocating returns include all of the following, except: Historical returns of each asset in the portfolio is not a good predictor of future returns of each asset in the portfolio Historical volatility is a good measure/predictor of future volatility of each asset in the portfolio Creating an SAA based on optimising returns against risk may not allocate to investments that are important in a portfolio Risk Parity based SAA are better diversified than equal $ allocated SAA. Retail investors better understand their desired level of volatility rather than their desired required returns
