Sell price vs average price vs return incorrect?

Hi all,

I hope someone can enlighten me on an issue I keep having.

One of my investments:

Return: -£4.36
Average price: $74.23
Sell price: $74.35

How can it be that my return is negative when sell price is higher than my average buying price? Is this due to exchange rate changes?

Most likely USD has weakened against GBP since date/time of your purchase, thus when your returns are converted from USD to GBP there is loss on the investment.
