iShares S&P500 - changes before US stock market opens

Hey

So the S&P500 tracks US companies. How come, before the USA Stock Market opens, the S&P500 is showing changes today?

Surely it would not until the market opens?

That fund is traded on an exchange that is currently open (I assume it’s the London Stock Exchange) and is priced in £.
There are many different versions of the same index tracker.

And futures market is open, which is a gauge for pricing the ETF.

Following gmullebr’s point, the market is irrational. The price will fluctuate for no sane reason as long as the market is open. Ignore it.
