Can anyone explain the difference?

Hi All,

New to investing, and still trying to understand something's. Looking at ETFs to invest in, and in doing my research the NASDAQ has outperformed the S&P 500 over the last 10 years. Come across these two ETFSs, they should be the same but there is a massive difference in returns over the last week. Can anyone explain this? I'm aware of the currency difference but that shouldn't explain one stock losing Vs one gaining should it?
