Given the following expectations for return, risk and correlation: An optimal portfolio of S and B has been calculated to contain 0.6 stocks, i.e. portfolio S (out of a possible 100% or 1.0 ). What would be the standard deviation of the optimal portfolio from S and B ? 0.1555 0.1472 0.1718 0.1628 0.1797 Given the following expectations for return, risk and correlation: An optimal portfolio of S and B has been calculated to contain 0.6 stocks, i.e. portfolio S (out of a possible 100% or 1.0 ).
