In this context, the volatility of the asset, and its correlation with the market portfolio, are historically observed and are therefore given.

RePEc uses bibliographic data supplied by the respective publishers. The above optimization finds the point on the frontier at which the inverse of the slope of the frontier would be q if portfolio return variance instead of standard deviation were plotted horizontally.

The implication is that a rational investor will not invest in a portfolio if a second portfolio exists with a more favorable risk-expected return profile — i.
