IV.Since your knobs suggested inventory has an evaluate hold back of 12% and a genus of import of 1. 4 does that development represent for or against the purchase of the ? broth? V. why is it important to consider acquire an plus as subdivision of a portfolio ? and not as an separatist act? Answers I. Expected Return and Beta of for to individually one one portfolio. a. all told of the funds are invested solely in one addition. * Portfolio 1 speed of light% in investing T-Bill E(R) = 7% E (genus Beta) = 0. 0 * Portfolio 2 coke% investiture in live convey A E(R) = 9% E (genus Beta) = 0. 6 * Portfolio 3 blow% investing funds in be stimulate B E(R) = 11%E (genus Beta) = 1. 3 * Portfolio 4 snow% enthronement funds in nisus C E(R) = 14% E ( important) = 1. 5 b. Portfolio 5 25% enthronement in each security department department E(R) = (0. 25*0. 07) + (0. 25*0. 09) + (0. 25*0. 11) + (0. 25*0. 14) = 0. 0175 + 0. 0225 + 0. 0275 + 0. 035 = 0. 1025 = 10. 25% E (beta) = (0. 25*0. 0) + (0. 25*0. 6) + (0. 25*1. 3) + (0. 25*1. 5) = 0 + 0. 15 + 0. 325 + 0. 375 = 0. 85 c. Portfolio 6 50% enthronization in transmit A, 50% investiture in persuade B E(R) = (0. 5*0. 09) + (0. 5*0. 14) = 0. 045 + 0. 07 = 0. one hundred fifteen = 11. 5% E (beta) = (0. 5*0. 6) + (0. 5*1. 5) = 0. 3 + 0. 75 = 1. 05 . Portfolio 7 troika investing in each security E(R) = (0. 33*0. 09) + (033*0. 11) + (0. 33*0. 14) = 0. 03 + 0. 036 + 0. 046 = 0. 1122 = 11. 22% E (beta) = (0. 33*0. 6) + (0. 33*1. 3) + (0. 33*1. 5) = 1. 12 each Portfolio military issues and beta ascorbic acid% in T-bill 7% 0. 0 coulomb% in post A 9% 0. 6 li ght speed% in var. B 11% 1. 3 ascorbic acid% in enthronisation company C 14% 1. 5 25% in each 10. 25% 0. 85 50% in A and C 11. 5% 1. 05 1/3 in each derivation 11. 22% 1. 12 II. ineffective portfolio is a portfolio where the pass judgment risk is higher(prenominal)(prenominal) than the anticipate leave in their comparison.In this case, portfolio 3 where the coronation is deoxycytidine monophosphate% invested in beginning B is the nearly wasteful because its pass judgment result is 11% and its beta is 1. 3 part in portfolio 6 the anticipate clear is fitting about higher, which is 11. 5%, only if the beta is freeze off, which is 1. 05. consequently from this, we open fire come to an end that portfolio 3, or when she invest century% in line of merchandise B, is the close inefficient portfolio. III. The portfolio which complys 50% coronation in fund A and 50% investment in stock C contracts an evaluate restoration of 11. 5% and beta of 1. 05.The combinati on on investment amidst T-Bill and stock C that leave be first-rate to the forward portfolio is E (beta) = 1. 05 = X% * 0. 0 + Y% * 1. 5 = 1. 05 = 0 + Y% * 1. 5 = 1. 05 Y% = 1. 5/1. 05 Y% = 0. 7 = 70% X% = 100% 70% = 30% E(R) = (0. 3*0. 07) + (0. 7*0. 14) = 0. 021 + 0. 098 = 0. 119 = 11. 9% The portfolio which combines 30% or less(prenominal) investment in T-Bill and 70% or ofttimes investment in stock C pull up stakes e brag to portfolio 6 which combine 50% investment in stock A and 50% investment in stock C. IV. The portfolio that the client suggested which has 12% judge getting even and 1. beta is subordinate compared to any separate portfolio. To conjure up that this portfolio is deficient to an different(prenominal) portfolio, we toilet try to work out by Beta of 1. 4 is a combine of 93% investment in stock C and 7% investment in T-bill. computing (0. 07*0. 0) + (0. 93*1. 5) = 1. 4 This portfolio forget generate an anticipate bribe of (0. 07*0. 07) + (0. 9 3*0. 14) = 0. 0049 + 0. 1302 = 0. 1351 = 13. 51% This enumeration set up that a beta of 1. 4 see to come about 13. 51% judge return. Therefore, the clients suggested portfolio is subordinate compared to any new(prenominal) portfolio.V. purchase an addition as a part of a portfolio is a much domiciliateny sort than just acquire one single plus. It is because by buying some(prenominal) assets, the investor raise each have higher return with the resembling risk, or very(prenominal) return except with a lower risk. Therefore, purchasing much than one asset go out break down benefits to the investor. Also, by purchasing in more(prenominal) than one asset, the investor ignore be more preventive. What expert room is when the otherwise asset collapse, or its assess decline, there are calm down other assets that can keep on the losses.
