What's happened?

Shares of technology companies have fallen sharply in the US and Asia as investors question how quickly artificial intelligence (AI) can continue to grow.

The falls followed the US midterm elections, when some candidates called for limits on new AI data centres - the buildings that house the computers needed to run AI.

European shares have also fallen, though less sharply than those in the US and Asia. Share prices have also fallen in other types of business, including retailers and healthcare companies.

This means the effects could reach a wider range of investments, not just those focused on AI. It's too early to know how long these falls might last or whether markets could fall further.

The key thing to remember is that the effects of these events are usually short-lived. Markets usually recover fairly quickly.

Investing should be for the longer term which can help ride out any of these short-term ups and downs in value.
