You have invested your savings in the VanVeck Blended ETF ('Exchange Traded Fund') that adopts a varied approach to portfolio construction by investing in multiple ETFs. The Blended ETF seeks to maintain the following ratios: 30% in the ASX200 ETF with a beta of 0.8. 30% in the Developed Market Index ETF, which is the worldwide market index. 30% in the Gold ETF with a beta of -0.2 (negative 0.2). The remaining 10% is allocated to a risk-free money market ETF earning the risk-free rate of 2% per year. Note: assume the worldwide market index is the CAPM market portfolio against which the risk of all other assets is assessed a) Given the expected market risk premium is 4% per year, what is the expected return of your Blended ETF portfolio? (4 marks b) Given that the market portfolio has a standard deviation of 25% and the correlation coefficient of your Blended ETF portfolio and market portfolio is 0.3, what is the standard deviation of your Blended ETF portfolio if CAPM theory holds?
