The U.S. economy grew at a 3.3% annual rate in the fourth quarter, according to the Commerce Department. Economists surveyed by FactSet had estimated 1.7% growth, while both the Federal Reserve Bank of Atlanta’s GDPNow and the New York Fed Staff Nowcast models put the number higher, at 2.4%. While Thursday’s data topped economists’ expectations, it is lower than the third quarter’s 4.9% reading.
