Answer: 0.82466
Step-by-step explanation:
You did not give the other information required to solve the question but here are some information that was gottten.
Portfolio Weight
HCE Corp = 0.25
Green Miget = 0.31
Alive and Well = 0.44
Volatility
HCE Corp = 10%
Green Miget = 27%
Alive and Well = 14%
Correlation with the Market Portfolio
HCE Corp = 0.43
Green Miget = 0.54
Alive and Well = 0.43
Beta of HCE Corp = (0.43 × 0.10)/0.10
= 0.43
Beta of Green Miget = (0.54 × 0.27)/0.10
= 1.458
Beta of Alive and Well
= (0.43 × 0.14 ) /0.10
= 0.602
The beta of the portfolio will then be calculated as the portfolio Weight multiplied by the beta of very stick and this will be
= (0.25 × 0.43) + (0.31 × 1.458) + (0.44 × 0.602)
= 0.1075 + 0.45198 + 0.26488
= 0.82436
