Difference in US Tech 100 and NASDAQ price

[MickyGee]

I've noticed this week that there has been about 200 points difference between the US Tech 100 index on IG and the NASDAQ index viewed on other websites (eg. news sites). This is occurring even when the market is open, so it's not just a difference after hours. Example below from this afternoon.

This difference doesn't show for the Wall Street/Dow Jones or US 500/S&P 500, only the NASDAQ. Not sure if this has always been the case either, just noticed it this week.

I'm on demo mode currently, in case that's relevant.

Wondering if anyone can explain? Thanks kindly 🙂

There are 2 Nasdaq indices - The Nasdaq composite (around 2500 companies) which is what you see on most of the news sites as just “Nasdaq” and the Nasdaq 100 which is what the IG Tech 100 is. If you search on the news/finance sites both will come up and you can see the difference.
