Which is the expected return of the portfolio? 2. Which is the standard deviation (risk) of the portfolio? 3. Which are the weights of each asset in the portfolio w1, w2, w3, w4? 4. Is the specific risk of the portfolio the weighted average of assets specific risk? 5. Is the total risk of the portfolio the weighted average of assets systematic risk? 6. Which return can expect the investor if leverages the optimal portfolio with risk free rate asset and is willing to accept a op = 20%? 7.

Which of the four securitiess could be labelled as agressive in the equity market jargon? Questions 9, 10, 11 and 12 refer only to Stock 3. 9.

A financial analyst estimates that the Expected Return of S3 is 22%. Based in the SML valuation, is the asset underpriced or overpriced? Finally, evaluate the change that would entail in the initial optimal portfolio a change in the correlation coefficients of stock 1 to: p1,2 = 0, 15, p1, 3 = 0, 45, p1,4 = 0, 35 13. Has the risk of the portfolio increased or decreased? 14. If an investor invests 10000 EUR in this optimal portfolio, which transaction and for which amount will make with S1
