Consider a portfolio formed of two risky assets whose returns have a correlation of 0.5. What can be said of the standard deviation of the global minimum-variance portfolio formed with these two risky assets? O It's greater than zero. It s equal to zero. It s between -1 and +1. It's the weighted average of the standard deviations of the two risky assets.

Suppose you create a portfolio with two securities: Security Security Weight (%) Security Variance (%) X 70 18 Y 30 22  If the correlation coefficient between the two securities is -0.2, what is the standard deviation of the portfolio？

Mean-variance expected utility is given by Eu = e-, where e is expected return, v is the variance of the portfolio and tis risk tolerance. Suppose an investor has risk-loving preferences. What can we say about the value of t? Select one: Ot1 O. t>0 O t=0

Assume I am holding a portfolio of two risky assets with standard deviations of 1. Assume also that I am holding the minimum variance portfolio of these two assets. I do not know the correlation of these assets but I do know that it's not equal to one. Which of the below statements is true based on the information above? 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 the following linear regression model: (R₁-r)= a; + b(RMkt - rf) + e; The b; in the regression: O measures the deviation from the best fitting line and is zero on aver- measures the sensitivity of the security to market risk. measures the diversifiable risk in returns.

Can the standard deviation of a portfolio be zero? Explain your answer.

in a Statistical sense, the Single Index Model is best characterized by: the Capital Market Line The Security Market Liner Regression of any asset as a linear function of the Market, plus mean-zero random error A regression of the Market, as a linear function of any given asset, plus mean-zero random error I

Assuming that the rates of return associated with a given asset investment are normally distributed; that the expected​ return, r​, is 18.7​%; and that the coefficient of​ variation, CV​, is 1.88​, answer the following​ questions:   a. Find the standard deviation of​ returns, sigma Subscript rσr. b. Calculate the range of expected return outcomes associated with the following probabilities of​ occurrence: (1)​ 68%, (2)​ 95%, (3)​ 99%.

1. Determine the expected return and the variance of the portfolio formed by the two assets S₁, S₂ with weights ₁ = 0.6, x2 = 0.4. The assets returns are described by the following scheme: scenario W1 2لا W3 probability 0.1 0.4 0.5 T1 -20% 0% 20% 12 -10% 20% 40%

Suppose the utility function is U = E(r) - 0.5Ao2. Draw the indifference curve corresponding to a utility level of 0.2 for an investor with a risk aversion coefficient of 3. Please note the vertical line indicates expected return, and plot standard deviation on the horizontal line.
