On the individual stock pages we can see our how much we have invested in that stock in what I assume is the stock default currency (based on where the stock is listed). E.g. for JNJ is in USD.
Since I’m based in UK, I’m paying for JNJ in GBP and if I scroll down I can see “Avg. price per share” that I paid for all my purchases in GBP.
Would it make more sense to show what’s my average price per share in USD for consistency there? To know how much I’ve paid on average compared with the current price I have to google X GBP in USD right now. The simplest way would be to show average price per share in USD based on the current exchange rate I suppose?
