Answer:
10.27% and 9.11%
Explanation:
The computation is shown below:
Given that
Year Price Dividend Return
1 $43.55
2 $48.53 $.87 13.43%
3 $57.45 $.90 20.23%
4 $45.53 $.95 -19.90%
5 $52.45 $1.00 17.39%
6 $61.53 $1.08 19.37%
Total 51.34%
Now the arithmetic average return is
= 51.34% ÷ 5
= 10.27%
And, the geometric average return is
= ((1 + 13.4328%) × ( 1+ 20.2349%) × (1 - 19.9049%) × (1 + 17.3951%) × (1 + 19.3708%))^(1 ÷ 5) - 1
= 9.11%
Working Note:
Rate of Return from year 1-2 = (Ending Price - Beginning Price+Dividend) ÷ Beginning Price
= ($48.53- $43.55 + 0.87) ÷ $43.55
= 13.4328%
Rate of Return from 2-3 = ($57.45 - $48.53 + $0.90) ÷ $48.53
= 20.2349%
Rate of Return from 3-4 = ($45.53 - $57.45 + $0.95) ÷ $57.45
= -19.9049%
Rate of Return from 4-5 = ($52.45 - $45.53 + 1) ÷ $45.53
= 17.3951%
Rate of Return from 5-6 = ($61.53 - $52.45 + $1.08) ÷ $52.45
= 19.3708%
