Question

Portfolio betas Rose Berry is attempting to evaluate two   possible portfolios, which consist of the same five assets held in different   proportions. She is particularly interested in using beta to compare the   risks of the portfolios, so she has gathered the data shown in the following   table.












Asset Asset Beta Portfolio A Portfolio B








1 1.3 10 30








2 0.7 30 10








3 1.25 10 20








4 1.1 10 20








5 0.9 40 20





















a. Calculate the   betas for portfolios A and B.







betas for portfolios   A =1.30*10%+0.70*30% + 1.25*10% +1.10*10% +0.90*40% =0.935



betas for portfolios   B =1.30*30% +.7*10% +1.25*20% +1.1*20% +.9*20% =1.11

















b. Compare the   risks of these portfolios to the market as well as to each other.  Which portfolio is more risky?

b. Compare the   risks of these portfolios to the market as well as to each other.  Which portfolio is more risky?














Explanation / Answer

betas for portfolios A= .0.935


betas for portfolios B= 1.11


portfolios WITH HIGH BETA ----------MORE risky-SO portfolios B=RISKY
