2. Risk and return estimates (4 marks): a. Use CAPM to estimate the expected return for the shares of: i) your case company; and ii} a hypothetical company with a negative beta of -D.2D as at 5 April, 2019. To do this, use the yield to maturity on that date of a 10-year Australian Government bond as a proxy for the risk- free rate, assume the market risk premium is 6% and use the company's most recent 5 year beta. b. Using the data from part 2a, estimate portfolio expected return and beta, assuming a portfolio made up of your case company and the hypothetical company in equal weighting. 3.
