单项选择题
An investor purchases a bond for $989.00. After 180 days the investor receives an interest payment of $ 25.10 and sells the bond for $1036.40. The investor's effective annual yield is closest to:（）
A. 14.66%
B. 15.20%
C. 15.42%
答案
参考答案：C
解析：
由题意可知，R1=(1036.40-989.00+25.10)/989.00=7.33%，因为是半年的收益率，而每年是365天，所以EAY=(1+7.33%)365/180-1=15.42%。
