Suppose you can only invest in risky asset 1 and 2 (asset 3 is not available). Calculate the portfolio weights of the minimum-variance portfolio with an expected return of 10%. What is the volatility of the portfolio? 2 2. Suppose now you invest in all three risky assets. Calculate the portfolio weights of the minimum-variance portfolio with an expected return of 10%. What is the volatility of the portfolio? 3. Suppose you can invest in all three risky assets and the risk-free rate is 2%. Calculate the portfolio weights of the tangency portfolio.
