下面这道题是2001年CFA一级考试题
A portfolio of non-dividend-paying stocks earned a geometric mean return of 5 percent between January 1,1994, and December 31, 2000. The arithmetic mean return for the same period was 6 percent. If the market value of the portfolio at the beginning of 1995 was $100,000, the market value of the portfolio at the end of 2000 was closest to:
a. $135,000
b.$140,000
c. $142,000
d. $150,000
答案是b。很显然,这是1加5%的7次方再乘以本金所得的结果,但我的问题是,这里为什么是7而不是6次方呢?
多谢大家的指教。
注意:从1994年初起算,当然是7年,但题中本金是从1995年初起算的,所以我认为应该是6,但此时的贴现率又是多少呢?
