You are a mean-variance investor, facing a risk-free rate of 2% and a risky asset with expected return of 10% and volatility (that is, standard deviation) of 20%. 1. Draw the two assets and the set of portfolios that you can form of these assets on a standard volatility/return diagram, like those that are on the slides. 2. If you have a risk-aversion coefficient of 0.5, what is the optimal portfolio of these two assets for you? What problem does the optimal portfolio solves? What changes if your risk-aversion coefficient is 0.9? Explain.
