Answer: 1.048
Explanation:
First let us calculate the amount in Con Edison
= 50,000 - 20,000 - 12,000
= $18,000
To calculate the Portfolio Beta, you take the sum of the respective betas of the various stocks in the portfolio multiplied by their proportion in the portfolio.
Intel = 20,000/50,000
= 2/5
GE = 12,000/50,000
= 6/25
Con Edison = 18,000/50,000
= 9/25
Adding them up we will have
= (1.3*2/5) + (1*6/25) + (0.8*9/25)
= 1.048
