CHAPTER 6 OPTIMAL RISKY PORTFOLIOS (a) for sure. (b) and (d) atomic number 18 firm-specific. (c) and (e) can be any firm-specific or due to market-wide factors. (a) and (c) enter into the portfolio part and thence alter portfolio risk. (a) is true by definition. (b) is also true: tell for pillowcase the example in Figure 6.15. (c) is false, since it cannot be the link portfolio. (d) may also be false. 4.The parameters of the opportunity set are: E(rS) = 20%, E(rB) = 12%, ?S = 30%, ?B = 15%, ? .10 From the streamer deviations and the correlation coefficient we generate the covariance matrix [note that Cov(rS,rB) = ??S?B]: Bonds Stocks Bonds 225 45 Stocks 45 900 The negligible-variance portfolio is free-base by applying the formula: wMin(S) = = = . 1739 wMin(B) = .8261 The minimum variance portfolio mean and measure deviation are: E(rMin) = .1739 × 20 + .8261 × 12 13.39% ?Min = [W?+ W?+ 2WSWBCov(S,B)]1/2 = [.17392 × 900 + .82612 × 225 + 2 × .1739 × .8261 × 45]1/2 = 13.92% 5. |% in stocks |% in bonds |Exp. return |Std.
