a. urv(w) = 0.07 (w) + 0.07 (1 - w) = 0.07
Std.dev(w) = ((w^2)*(0.18)^2) + ((1-w)^2)*(0.14)^2) + 2*w*(1-w)*0.14*0.18*(-1)
b. Weight of asset A for minimum variance(risk) = (σb²-ρabσaσb) / (σa² + σb² – 2ρabσaσb)
Putting the values and solving the equation gives => w(1) = 43.75%
w(2) = 100 - 43.75 = 56.25%
Portfolio return = 0.4375*0.07 + 0.5625 *0.07 = 0.07 or 7%
Give a thumbs up if this helped :)
Consider a portfolio consisting of the following two risky assets. Asset i Hi, Return on Asset...
2. (Understanding optimal portfolio choice) Consider two risky assets, the expected return of asset one is μ-0.1, the expected return of asset two is μ2-0.15, the risk or standard deviation of asset one is σ1-0.1, the risk or standard deviation of asset two is σ2-02. The two assets also happen to have zero correlation. An investor plans to build a portfolio by investing w of his investment to asset one and the rest of his investment to asset two. Calculate...
1. Consider a portfolio P comprised of two risky assets (A and B) whose returns have a correlation of zero. Risky asset A has an expected return of 10% and standard deviation of 15%. Risky asset B has an expected return of 7% and standard deviation of 11%. Assuming a risk-free rate of 2.5%, what is the standard deviation of returns on the optimal risky portfolio? a) 9.18% b) .918% c) .84% d) 8.42%
Assume that you manage a risky portfolio with an expected rate of return of 17% and a standard deviation of 27%. The T-bill rate is 7%. A client prefers to invest in your portfolio a proportion (y) that maximizes the expected return on the overall portfolio subject to the constraint that the overall portfolio's standard deviation will not exceed 20%. a. What is the investment proportion, y? (Round your answer to 2 decimal places.) Investment proportion y...
What is the expected return and standard deviation of a portfolio consisting of $4200 invested in a risk-free asset with an 6.9-percent rate of return, and $1400 invested in a risky security with a 18.9-percent rate of return and a 23.9-percent standard deviation?
Eric is dividing his portfolio between two assets, a risky asset that has an expected return of 30% and a standard deviation of 10%, and a safe asset that has an expected return of 10% and a standard deviation of 0%. Eric's budget constraint is rx= 2σ?+10. Eric’s utility function is ?(??,σ?)=???(??,30−2σ?). What are his optimal values of ?? and ???
You manage a risky portfolio with an expected rate of return of 18% and a standard deviation of 29%. The T-bill rate is 5%. Suppose that your client prefers to invest in your fund a proportion y that maximizes the expected return on the complete portfolio subject to the constraint that the complete portfolio's standard deviation will not exceed 18%. a. What is the investment proportion, y? (Round your answer to 2 decimal places.) Investment proportion y b. What is...
Assume that you manage a risky portfolio with an expected rate of return of 14%and a standard deviation of 38%. The T-bill rate is 4%. A client prefers to invest in your portfolio a proportion (y) that maximizes the expected return on the overall portfolio subject to the constraint that the overall portfolio's standard deviation will not exceed 25%.a. What is the investment proportion, y ? (Do not round Intermediate calculations. Round your answer to 2 decimal places.)b. What is the...
You have been asked for your advice in selecting a portfolio of assets and have been supplied with the following data: You have been told that you can create two portfolios-one consisting of assets A and B and the other consisting of assets A and C-by investing equal proportions (50%) in each of the two component assets. a. What is the average expected return, r, for each asset over the 3-year period? b. What is the standard deviation, s, for...
Consider the following two assets. Returns on asset 1 has a mean of ui and standard deviation of 01. Returns on asset 2 has a mean of j2 and standard deviation of 02. The correlation coefficient p1,2 measures how the two assets' returns are correlated, and it takes on values between -1 and +1. An investor puts W1 fraction of her wealth into stock 1, and W2 =1-W1 fraction of her wealth into stock 2. 1. Using the equation on...
You invest $100 in a complete portfolio. The complete portfolio is composed of a risky asset with an expected rate of return of 12% and a standard deviation of 10% and a treasury bill with a rate of return of 5%. __________ of your complete portfolio should be invested in the risk-free asset if you want your complete portfolio to have a standard deviation of 9%.
