Firstly, sorry if the terminology of my question is not correct, I'm quite new to investing.
I am having trouble understanding the differences between two ETF's that follow the same index (a specific example would be Vanguards S&P 500(code VOO) and Vanguards S&P 500 UCITS GBP (VUSA))
..I understand that they are on differing markets and one is compliant with EU'S UCITS regulations and are both hosted in different countries. But what is the reason for the price difference and why is it this way.
Again, sorry about the shoddy terminology/lack of articulation; this is a rather new topic for me and is a massive learning curve.
