Weighted Average Changed – Exchange Rate?

Hi all,

Very basic question here but I noticed recently my average investment in a stock changed recently. Let’s say it was sat at an average of $100 it is now $102.

I deal in the UK so GBP. Is this because the dollar is rising against pound sterling?

If the dollar continues to increase against 1GBP then the average will automatically go up and if it goes down so will the average?

Thanks.
