问题如下:
If annual rate is 14.31% for the financial market, what is the effective annual rate assuming compounded quaterly?
选项:
A.18.81%.
B.15.38.
C.15.10%.
解释:
C is correct.
EAR = [(1 + (0.1431 / 4)]4-1 = 15.10%
老师怎么能看出来题中,14.31%只是“年化”利率, 并不是真实的可获得的年利率,并不代表年初存100元钱,年末就会获得14.31元。这个14.31%只是写出来便于比较的。 为什么不能用(1+r/4)4=1+14.31 ?
