What are the different types of expected return and related risk, for individual assets and for portfolios as a whole. Explain carefully what each type represents and give examples in each case. What type of expected returns does the CAPM model capture? What type of expected return and risk you are exposed to if you have the FTSE 100 INDEX only in the portfolio?
The market portfolio (M) has the expected rate of return E(rM) = 0.12. Security A is traded in the market. We know that E(rA) = 0.17 and βA = 1.5.
(1) What is the rate of return of the risk-free asset (rf)?
(2) Security B is also traded in the market. βB = 0.8. Then what is “fair” expected rate of return of security B according to the CAPM?
(3) Security C is a third security traded in the market. βC = 0.6, and from the market price, investors calculate E(rC) = 0.1. Is C overpriced or underpriced? What is αC?
1. What are the two most important inputs one needs in order to model default risk within their portfolios? (Bloomberg)

- Question #1. Portfolio theory tends to define risky investments in terms of just two factors: expected returns and variance (or standard deviation) of those expected returns. What assumptions need to be made about investors and the expected investment returns (one assumption in each case) to justify this ‘two-factor’ approach? Are these assumptions justified in real life? ‘The expected return from a portfolio of securities is the average of the expected returns of the individual securities that make up the portfolio, weighted by the value of the securities in the portfolio.’ ‘The expected standard deviation of returns from a portfolio of securities is the average of the standard deviations of returns of the individual securities that make up the portfolio, weighted by the value of the securities in the portfolio.’ Are these statements correct?
