Markets sank on Monday, extending last week’s losses, as investors took in the latest grim forecasts about the sudden surge in the Omicron variant and after a big setback in President Biden’s efforts to pass a comprehensive domestic policy bill.

The stock market initially rallied after the announcement. But now, investors have fully digested the Fed’s plans, raising concerns that “a rapid increase in rates might cause economic growth to slow,” she wrote in a research note.

Shares of technology stocks, which are sensitive to changing views on interest rates, have fallen in recent weeks. Meta, Facebook’s parent company, fell 2.5 percent on Monday, while Amazon, Apple …….
