SP 500 Question


Could someone explain how come CSPX ETF USD (https://www.marketwatch.com/investing/fund/cspx?countrycode=uk) which tracks SP500 index is only down 0.55% today, while the actual index is down more than 9% at the same time? (Marketwatch link - https://www.marketwatch.com/investing/index/spx?mod=home-page
Shouldn’t both be down equally?

Thanks for advice

Because it is traded in London. So today’s losses stopped after London closed.

Don’t worry, you’ll get those losses tomorrow :grimacing:
