US Open Market Brief, Tuesday 20 October.
General Motors reported better results than expected this morning, but its shares are falling before the US market opens. The company is not raising its profit forecast because its costs are rising, including the memory chips that go into modern cars.
Those same memory chips are in huge demand from AI data centres, which is pushing their price up for everyone else.
3M, which sells parts to data centres, is rising after a good quarter and a bigger deal with Amazon. Oil prices are higher after more attack claims in the Gulf.
The US stock market opens at 14:30 UK time.
Full brief:
GM beat forecasts but fell before the open as memory chip costs hit its outlook, while 3M rose on an Amazon data centre deal and Brent hit a five-month high.
