Same fund, three tickers, four currencies. Which line are you on?
The ISIN is 12 characters and the same everywhere. Its first two letters give the country: IE for an Irish fund.
The ticker is given by each exchange. One €131 billion world ETF has 10 listings and 3 tickers (justETF).
And one of those tickers trades in euros in Milan and in pounds in London.
A line in dollars, bought from a euro account, adds an FX fee.
Do you look up your ETF by ISIN or by ticker?
