Major US stock indices extended losses on Friday to close at levels not seen since mid-July, as the concerning warning from FedEx reaffirmed investors’ worries about the darkening global growth outlook. The Dow closed almost 140 points lower, while the S&P 500 and the Nasdaq dropped 0.7% and 0.9%, respectively. FedEx shares plunged over 20% after it withdrew its full-year guidance and announced cost-cutting measures, citing “significantly worse” global economic trends that are set to compound as major central banks tighten monetary policy to combat surging inflation. All three benchmarks notched their fourth losing week in five, with the Dow Jones shedding over 4%, the S&P 500 retreating nearly 5%, and the Nasdaq falling 5.5%, pressured by sharp declines in policy-sensitive sectors.
