Suppose that you are told that the minimum variance portfolio has an expected return of 5% and a variance of 16. All investors have portfolios that are on the efficient frontier. If investors don’t have access to a risk-free asset, what can you conclude about the returns and variance of any investor’s portfolio? The expected return and variance are greater than or equal to 5% and 16 respectively. The expected return and variance are less than or equal to 5%...

A2 a) As per the CFA guide on ‘Portfolio Concepts’, an “investor’s objective in using a mean–variance approach to portfolio selection is to choose an efficient portfolio”. Discuss what is meant by an ‘efficient portfolio’. Then explain how minimum-variance portfolios are used to construct an efficient frontier. Plot a hypothetical efficient frontier and denote the minimum variance portfolio. (b) “If an investor can make money through passively investing using Exchange Traded Funds (ETFs) in a rising index, there is no...

Why do investors invest in real estate? Answer this from a portfolio theory perspective, considering the trade-off between portfolio risk and return. (Hint: What is the primary role of typical income property real estate within the portfolio? Is it bought to achieve a high average return?)

Explain the concepts of variance (total risk) and beta (systematic risk) in portfolio theory and the capital asset pricing model. Also explain why according to the capital asset pricing model that total risk should not be rewarded by the capital market. You may use diagrams in your explanation if you wish.

1. Consider an investor with $1 of wealth. He has to compose a portfolio with the following two risky assets. The rates of returns from those assets are specified by expectations, variances and correlations. var[r 1] = 0.02 E[r 1] = 0.05 var[r 2] = 0.03 E[r 2] = 0.08 corr[r 1, r 2] = 0.7 (a) Draw an efficient frontier of the investor. (b) How will the mean-variance efficient frontier in (a) change if corr[r 1, r 2] =...

Give me a complete explanation of portfolio diversification. GRAPHS must be a major part of your explanation. Be sure to explain what each graph is showing! Start with the simple two-asset case and move to the more complex multi-asset case with the efficient frontier, the effect of the risk free rate on investor choices, the investor’s indifference curve, and why all investors should end up choosing the market portfolio as the risky part of their portfolio.
