Answer :
Answer:
By definition, we know that Beta for market Portfolio is 1. By this, we need weighted average of J and K Beta as 1
1.38x + 0.93(1-x) = 1
1.38x + 0.93-0.93x = 1
0.45x = 0.07
x = 0.07/0.45
x = 0.16
So, we need 0.16 of J and 0.84 of K.
Weighted Average of J = 0.16 and K = 0.84.
Further Expected return of portfolio will be:
Weight Expected Return Expected Return of Portfolio
J 0.16 14.06 2.25
K 0.84 11 9.24
Total Portfolio Expected Return 11.49
