Answer:
Beta= 1.26
Explanation:
First, we will calculate the proportion of the portfolio of each security:
Security A= 600/1,000= 0.6
Security B= 400/1,000= 0.4
Now, the beta of the portfolio:
Beta= (proportion of investment A*beta A) + (proportion of investment B*beta B)
Beta= (0.6*1.5) + (0.4*0.9)
Beta= 1.26
Based on the amount invested and the various betas, the beta of the portfolio is 1.26
The beta of the portfolio will be a weighted average of the amounts invested in each security.
First find the value of the portfolio:
= 600 + 400
= $1,000
Beta is:
= (600 / 1,000 x 1.5) + (400 / 1,000 x 0.90)
= 1.26
In conclusion, the beta of the portfolio is 1.26
