My point with expected return is how each investor calculates this may be different resulting in different expected returns. If so different investors can arrive at different decisions even though both are rational.
As far as beta goes, this measure of risk is only relevant where there is a high correlation between the asset and the market. Therefore i don't think it is relevant to AKK.
