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.

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.

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.

a)define market risk.       b)define delta-hedged position and describe delta hedging.      c)describe gamma hedging and vega hedging.       d)define and explain value at risk (VAR).       e)describe the analytical (variance-covariance) method of calculating VAR, and discuss its advantages and disadvantages.

Suppose that there are four risky assets whose expected returns E(r) and variance- covariance matrix (S) are shown in the spreadsheet below.

Question 1 Are the following statements true or false? Provide a short justification for your answer. (You are evaluated on your justification.) Remember that a statement is false if any part of the statement is false. A single correct counterexample is sufficient to show that a statement is false. a) assets A, B, C, with expected returns and standard deviations: Suppose you are a mean-variance optimizer. The risk-free rate is 3%. There are three risky E [řa] = 10%, SD [FA] = 5% E [řB] = 15%, SD [řB] = 7% E [řc] = 12%, SD [řc] = 9% You cannot invest in all three risky assets. Instead, you have to choose whether to invest in only assets (A, B), or only assets (A, C). Asset B mean-variance dominates asset C, since it has higher return and lower standard deviation than asset C. Thus, as long as you are risk-averse, you would always prefer the set of assets (A, B) to the set assets (A, C). b) the same market B's. The covariance matrix between A, B, C is: Suppose the CAPM holds. Consider…
