Answer:
3.15%
Step-by-step explanation:
The computation of the arithmetic average rate of return is shown below:
Arithmetic mean = (Year 1 + year 2 ...... Year n return) ÷ (Total number of years)
The rate of return is
= (Capital gain + dividend) ÷ Price
For 2010 - 2011 = ($110 - $100 + 4) ÷ $100 = 14%
For 2011 - 2012 = ($90 - $110 + $4) ÷ $100 = -14.55%
For 2012 - 2013 = ($95 - $90+ 4) ÷ $90 = 10%
Now the arithmetic average rate of return is
= (14% - 14.55% + 10%)
= 3.15%
