Final answer:
To create a portfolio with an expected return of 12.4 percent, you should invest $154,800 in stock H and $103,200 in stock L.
Step-by-step explanation:
To achieve an expected portfolio return of 12.4%, you will need to invest a certain amount in stock H and stock L, which have expected returns of 14.3% and 10.9% respectively.
Let the investment in stock H be $x and investment in stock L be $y. The total investment is $258,000, so:
x + y = $258,000
For the desired portfolio return of 12.4%, the following equation must be satisfied:
0.143x + 0.109y = 0.124($258,000)
Solving these equations gives:
- Investment in stock H: $154,800
- Investment in stock L: $103,200
