Deteriorating investor enthusiasm for high-valuation growth companies and a mixed start to the fourth-quarter earnings season made for a volatile week.

Stock prices retreated last week as global central banks joined the Federal Reserve in taking steps to tighten monetary policy.

A more benign reassessment of the possible economic risk posed by Omicron sent stocks sharply higher last week.
