European stocks opened lower on Friday as doubts about the Federal Reserve's ability to cut U.S. interest rates in the face of strong economic data further dampened investor sentiment. Europe's benchmark index is heading for its worst weekly performance in more than a month, and the rebound in global stocks this week has also weakened. Francois Rimeu, a strategist at Français Asset Management, said that as long as expectations of the first rate cut are only postponed for a few months, it will not change the general narrative, which is "so far so good." He pointed out that the U.S. economy is resilient and inflation is basically under control.
