You want to create a portfolio with a beta of 1.5. You want to accomplish this goal by investing in a mutual fund that follows the market and in a stock with a beta of 3.0. Assuming you have $28,100 to invest, how much (in $) do you need to invest in the market fund?
Total amount of Investment to make = $28,100
You will invest in a Mutual fund that invest in Market Fund and in Stock
Beta of market fund is 1 (Note- market Beta is always 1)
Stock Beta = 3
Portfolio beta = 1.5
Let the weight of Market fund be X
So, Weight of Stock will be (1-X)
Portfolio Beta = (Weight of Market fund)(Beta of market fund) + (Weight of Stock)(Beta of Stock)
1.5 = X*1 + (1-X)*3
1.5 = X + 3 - 3*X
2*X = 1.5
X = 0.75
So, weight of market fund is 0.75
Amount to be invested in the market fund = $28,100*0.75
Amount to be invested in the market fund = $21,075
