I noticed that some funds are available under different ISINs.
For example the HSBC FTSE EPRA NAREIT DEVELOPED UCITS ETF:
When looking them up I can't identify real differences - just perhaps that (at least) at some stock exchanges just one of them is traded.
So, are these ISINs just aliases? How can I see that?
(I assume there are other cases where there are real differences - e.g. whether dividends are reinvested or not.)
Are there any advantages of buying one over the other?
What is the motivation for a bank like HSBC to create multiple ISINs for a fund?
