请问dividendpaid 不是自己付出的？这是持有获得的？

问题如下：

Using following data to calculate the total return on a share of equity:

Purchase price: $20

Sale price: $28

Dividend paid during holding period: $1

选项：

A.

45%

B.

15%

C.

22%

解释：

A is correct.

R_t = (P_t – P_t-1 + D_t)/P_t-1. Therefore, total return = (28 – 20 + 1)/20 = 45.0%.

考点：Risk And Return, Market Value and Book Value, Required Return

这道题考点是total return，投资一只股票的总收益包括dividend红利和price change即资本增值，基础班讲义P155页。total return的计算公式=(价格变化+期间获得的红利)/一开始的初始投资。
