You are shown the following Markowitz frontier and capital market line from a UK perspective, when combining UK stocks with germane stocks. UK stocks have an expected return of 4% and a standard deviation of return of 15%. German stocks have an expected of 10% and a standard deviation of returns of 22%. The correction between UK and German equity returns is -0.5. The UK risk free rate is 2.5%. You wish to construct the optimal portfolio with a standard deviation of returns of 5%. What is the expected return to this portfolio? Approximately what proportion of your assets should you place in UK equities, German qualities and the risk-free asset to achieve the optimal portfolio with this level of risk? How does your answer to part (a) change if you are prepared to have a standard deviation of returns of 20%? You are not permitted to short-sell equity and are unable to borrow.
