  1. CFA I
  2. Portfolio

问题如下：

A financial planner has created the following data to illustrate the application of utility theory to portfolio selection:

If an investor’s utility function is expressed as U=E(r)− 1 2 A σ 2  and the measure for risk aversion has a value of -2, the risk-seeking investor is most likely to choose:

选项：

A.

Investment 2.

B.

Investment 3.

C.

Investment 4.

解释：

C  is correct.

Investment 4 provides the highest utility value (0.2700) for a risk-seeking investor, who has a measure of risk aversion equal to −2.

第四个组合：U=18+0.5*2*0.3^2=18.09

第三个组合：U=20+0.5*2*0.15^2=20.0225

选第三个组合才对吧？
