Answer:
1.11
Explanation:
Calculation for what will the portfolio's new beta be
First step is to Calculate the weight of each investment
Stock E $ 50,000 / $ 2,00,000
Stock E= 0.25
Stock B $ 50,000 / $ 2,00,000
Stock B= 0.25
Stock C $ 50,000 / $ 2,00,000
Stock C = 0.25
Stock D $ 50,000 / $ 2,00,000
Stock D = 0.25
Now let calculate the portfolio new beta
Weight Beta
Stock E 0.25* 1.45 = 0.36
Stock B 0.25 * 0.80 = 0.20
Stock C 0.25* 1.00 = 0.25
Stock D 0.25 * 1.20 = 0.30
Total 1.11
(0.36+0.20+0.25+0.30)
Therefore portfolio's new beta will be 1.11
