Find the weights for the optimal risky portfolio. Assuming risk-free rate is 3%.
E(rs) =10%
E(rB )= 5%
σs = 15%
σB = 6%
PBS = 0.3
In Optimal Portfolio the Capital Allocation Line(CAL) is tangent to the efficient frontier of portfolio frontier. At this point CAL is maximum, thus returning maximum return for per unit additional risk.
Since, W(s) + W(b) = 1 ......(1)
where W(s) & W(b) are the respective weights of assets in an optimal portfolio.
and this W(rs) is calculated as,
substituting the values in the above equation:
=
= 0.4313 or 43.13%
Therefore,
= 1 -
= 1 - 0.4313
= 0.5687 or 56.87%

Consider two risky assets A and B with E(rA)= 15%, Sigma= 32%, E(rB)= 0.09, Sigma B= 23%, corrA,B= 0.2. The risk free rate is 5%. The optimal risky portfolio of comprised of the two risky assets is to allocate 64% to A and the rest to B. What is the standard deviation of the optimal risky portfolio
Under MPT (Modern Portfolio Theory), what do the risk-free rate and the optimal risky portfolio create and why is it important relative to all other possible portfolios (with the exception of the optimal risky portfolio)?

The risk-free rate is 5%. A risky portfolio has an expected return of 10% and a standard deviation of return of 20%. If you want to form a complete portfolio from these two assets, and you want this portfolio to have an expected return greater than 5% but less than 10% what must you do? Assume that all borrowing and lending can be done at the risk-free rate. a. Lend at the risk free rate b. borrow at the risk...
