Question
Consider two financial assets, X and Y, traded isolated or as part of a portfolio. All investors take decisions according to mean-variance analysis. Historic return
Consider two financial assets, X and Y, traded isolated or as part of a portfolio. All investors take decisions according to mean-variance analysis. Historic return information is available at no cost for everybody. The following estimates are computed with that information.
a) Compute expected returns, standard deviations and correlation coefficient for both assets.
b) Compute the weights for the global minimum-variance two-asset portfolio. What is its expected return and standard deviation?
c) What will be the return of portfolio P, which has a = 2.35151%? Is portfolio P efficient?
d) What will be the risk (standard deviation) of portfolio K with expected return equal to 7.18%? Is portfolio K efficient?
e) What is the expected return and risk (standard deviation) of portfolio Q, where 120% of the budget is invested in asset Y? Is portfolio Q efficient?
f) Draw an expected return-standard deviation diagram indicating single assets and portfolio.
