单选题 An analyst does research about foreign investments. Which of the following is least likely to increase estimated required rate of return by foreign investors to purchase domestic securities?
A. Exchange rate risk.
B. Real GDP growth rate.
C. Capital liquidity limitation.

【正确答案】 B

【答案解析】[解析] 汇率风险和资本流动性障碍会增加国外投资者投资于本国的必要回报率，必要回报率等于名义无风险回报率加上风险溢价，而真实的GDP增长率并不会直接反映在必要回报率中。
