Answer:
1.7202
Explanation:
The computation of the beta for the other stock is shown below:
We assume that the risk free assets has beta of 0
And, the market beta = 1
So the equation would be
Market beta = 1 ÷ 3 × 0 + 1 ÷ 3 × 1.28 + 1 ÷ 3 × beta
1 = 0 + 0.4266 + 1 ÷ 3 beta
1 - 0.4266 = 1 ÷ 3 beta
0.5734 = 1 ÷ 3 beta
So, the beta is
= 0.5734 × 3
= 1.7202
Hence, the beta for the other stock is 1.7202
