Explanation / Answer

1) Calculation of expected return

= Return in boom condition * Probability of boom + Return in recession condition * Probability of recession

= 13%* 0.81+3%*0.19

= 10.53+0.57 i.e 11.07

Deviation in boom = 11.07-13 i.e -1.93

Deviation in recession = 11.07-3 i.e 8.07

Devaition in boom^2 = 3.7249

Deviation in recession ^2 = 65.1249

2) Portfolio weight of stock C = Investment in stock C / Total Investment

= 400*60/(120*40+600*36+400*60+280*59)

= 24000/( 4800+21600+24000+16520)

= 24000/66920

= 35.86 percent

3) Expected rate of return = Risk free return + Beta * Market risk premium

= 4.6%+1.7*14

= 28.40 percent
