Document Summary

Chapter 11: risk and return : the capital asset pricing model (capm) 11. 1 the portfolio weight of an asset is the total investment in that asset divided by the total portfolio value. First, we will find the portfolio value, which is: Total value = (135 shares ) + (105 shares ) = ,650. Weighta = (135 shares ) / ,650 = 0. 5958. Weightb = (105 shares ) / ,650 = 0. 4042. 11. 2 the expected return of a portfolio is the sum of the weight of each asset times the expected return of each asset. Investment in stock a = ,900; investment in stock b = ,300. Return on stock a = 10%; return on stock b = 15% Total value of the investment = ,900 + ,300 = ,200. Expected return of this portfolio = (,900 / ,200) (10%) + (,300 / ,200) (15%) = 12. 74%
