O Portfolio's standard deviation is equal to 1/2. Portfolio's return is equal to 1/2. O Portfolio weights of the two assets are equal to 1/2. None of the above statements is true. Portfolio's Sharpe ratio is equal to 1/2.
Consider two risky assets that have returns variances of 0.0625 and 0.0324, respectively. The assets' standard deviations of returns are then 25% and 1 8%, respectively. Calculate the variances and standard deviations of portfolio returns for an equal-weighted portfolio of the two assets when their correlation of returns is 1.
