Answer:
1.15
Explanation:
A diversified portfolio consists of $100,000 with 20 stocks and $5,000 invested in each of the stock
The portfolio beta is 1.12
You plan to sell a stock with a beta of 0.90, the proceeds gotten from it will be used to purchase a new stock with a beta of 1.50
Therefore, the portfolio's new beta can be calculated as follows
= (20×1.12-0.9+1.50)/20
= (22.4-0.9+1.50)/20
= 23/20
= 1.15
Hence the portfolio's new beta is 1.15
