不管怎么样都选sharp ratio最大的。然后其他的可以用现金来调整。

问题如下：

Based on Exhibit 1 and the risk aversion coefficient, the preferred asset allocation for Perkins is:

选项：

Asset Allocation A.

Asset Allocation B.

Asset Allocation C.

解释：

C is correct.

The risk aversion coefficient (λ) for Mary Perkins is 8. The utility of each asset allocation is calculated as follows:

Asset Allocation A:U_A = 10.0% – 0.005(8)(12%)²= 4.24%

Asset Allocation B:U_B = 8.0% – 0.005(8)(8%)²= 5.44%

Asset Allocation C:U_C = 6.0% – 0.005(8)(2%)²= 5.84%

Therefore, the preferred strategic allocation is Asset Allocation C, which generates the highest utility given Perkins’s level of risk aversion.
