The Fed decision on Dec. 18 stateside will also be top of mind for investors, with the CME Fedwatch tool currently forecasting a 98.2% chance of a 25-basis-points cut.

Contrary to the general upward trend, market darling Nvidia, the artificial intelligence chipmaker that had driven stock gains over the past two years, saw a 1.7% decline. This drop pushed the stock into correction territory, falling over 10% from its recent all-time high in November.
