Security "Y" goes down on average by 16% when the market goes up and goes up by 16% when the market goes down. Security "Z" goes up on average by 4% when the market goes up and goes up by 4% when the market goes down.

Explanation / Answer

1. Security Z goes up 4% irrespective of the market portfolio movement, hence it must be the risk free security. Thus the risk free rate is 4%.

Now denoting market return by Rm, we have :

Rx = 29% = 4% + Betax * (Rm - 4%) - solving for Rm = 24%, we get Betax = 1.25

Ry = -16% = 4% + Betay * (Rm - 4%) - solving for Rm = 24%, we get Betay = -1

Expected Market Return = 0.5 * 24% + 0.5 * -8% = 8%

Expected Return for stock with Beta 0.8 : 4% + 0.8 * (8%-4%) = 7.20%

3. option (b) a portfolio of security with similar risks

8. Expected Return = 75% * 25% + 25% * 50% + 25% * -25% = 25%

Variance = [25% * (75%-25%)2 + 50% * (25%-25%)2 + 25% * (-25%-25%)2 = 0.125

Standard Deviation = (Variance )1/2 = 0.125(1/2) = 35.36%
