The portfolio’s new beta will be 1.125
Explanation:
In this question, we are interested in calculating the portfolio’s new beta given the value of the beta of the stock which is used in replacing it.
We apply a mathematical approach here.
Mathematically;
Portfolio beta=Respective beta * Respective investment weight
=(50,000/200,000*1.5)+(50,000/200,000*0.8)+(50,000/200,000*1)+(50,000/200,000*1.2)
= 0.375 + 0.2 + 0.25 + 0.3 = 1.125
