Answer:
27%
Explanation:
Given the following sorted data from the question:
Seminole Market Portfolio
Average Return 18% 14%
Standard Deviation of Returns 30% 22%
Beta 1.4 1.0
Residual Standard Deviation 4.0% 0.0%
Therefore, we have:
Percentage of investment in Seminole Fund = Market portfolio SD of returns / Seminole SD of returns = 22% / 30% = 73.33%, or 73%
Percentage of investment in T-Bills = 100% - 73% = 27%
Therefore, the percentage of the adjusted portfolio that would need to be invested in T-Bills is 27%.
