Answer:
0.68
Explanation:
A portfolio consists of an investment of $7,500
The amount of common stock is 20
The portfolio beta is 0.65
Suppose one of the stock in the portfolio is sold with a beta of 1.0 for $7,500
The proceeds realized is then used to purchase another stock with a beta of 1.50
The first step is the to calculate the change in beta
Change in beta= 1.50-1
= 0.5
The next step is to divide the change in beta by the number of common stock
= 0.5/20
= 0.025
Therefore, the new beta can be calculated as follows
= 0.65+0.025
= 0.68
Hence the new portfolio's beta is 0.68
