Answer:
16.67%
Explanation:
Holding period return = [(actual value - purchase cost) + dividends received] / purchase cost.
First we can calculate the HPR in euros = [(1.15€ - 1€) + 0€] / 1€ = 0.15 = 15%
We now need to convert our earnings to US dollars. We will gain an additional 10% due to the currency appreciation of the euro:
total percentage rate of return = 15% / (1 - 10%) = 15% / 0.90 = 16.67%
