Which portfolio is most appropriate for Washington?

选项：

A.Portfolio A

B.Portfolio B

C.Portfolio C

解释：

C is correct. Although Portfolios B and C have lower returns for the same expected standard deviation compared to the mean variance optimization (MVO) portfolio, Washington’s other preferences argue for some modest adjustments. Specifically, she will be retiring in Portugal, so her lifetime expenses will be denominated in Euro, and she perceives real estate and commodities to be high risk. Furthermore, her risk-averse utility function argues in favor of conservatism. Portfolio C has modest allocations to real estate and commodities, is underweight US stocks, and overweight bonds and European stocks. All of these positions are aligned with Washington’s preferences. Although Portfolio B avoids real estate and commodities entirely, it is significantly overweight US stocks and is only slightly overweight European stocks, suggesting a possible mismatch.
