Question 1. Portfolio Analysis (2 points) a) Assume the following about assets A and B: E[7]0.1, -0.09, E[TB] =0.08, o -0.04. Which one has lower absolute risk and which one has lower relative risk? (1): b) Find the mean return, E[r.), and variance, oz. of a portfolio consisting of 70% of your total wealth invested in asset A (w4=0.70), and 30% of your total wealth invested in asset B (Wg= 0.30). The correlation between assets A and B (P3) = 0.25 (1): (2): c) Now assume that the correlation is -0.5. Use the information above to calculate the variance of this new portfolio. Explain how the riskiness of the portfolio changes
