Answer: 0.92
Explanation:
Beta is a measure of riskiness and Market beta is always 1.
The total portfolio therefore has a beta of 1.
Portfolio Beta is weighted average of the betas of the composite stocks.
The stocks are equally invested in so their weights are 0.5.
Assume the beta needed is x.
(0.5 * 1.08) + (0.5 * x) = 1
0.54 + 0.5x = 1
0.5x = 1 - 0.54
x = 0.46/0.5
= 0.92
