European stocks weren't fazed by Nvidia's gloomier-than-expected guidance on Thursday, with rising economic confidence levels giving investors one reason to feel cheerful. The European Commission's Euro-area economic confidence indicator was published on Thursday and showed that sentiment climbed to 96.6 in August, up from 96 the previous month. While that could be taken as a positive sign, Capital Economics' Andrew Kenningham warned the jump could be down to a one-off boost from the Paris Olympics, rather than a longer-term recovery in growth.
