Expert Solution


Bet of the Portfolio = Weight of Stock 1 X Beta of Stock 1+ Weight of stock 2 X Beta of Stock 2
1.80 = 0.50 X 1.20 + 0.50 X Beta of Stock 2
1.80 = .60 + 0.50 X Beta of Stock 2
0.5 Beta of Stock 2 = 1.80 - 0.60
0.5 Beta of Stock 2 = 1.2
Beta of Stock 2 = 1.2 / 0.5
Beta of Stock 2 = 2.4

Answer = Beta of the second stock = 2.40
