U.S. GDP growth slowed in the fourth quarter, gaining just 1% from the third quarter. For the full year the U.S. economy contracted by 3.5%. That makes 2020 the first time that the economy has contracted for a full year since 2009 and the Great Recession. At the bottom of that recession that economy contracted by 2.5%. 2020 is also the worst year for economic growth since 1946 when the economy shrank by 11.6% as the country demobilized after World War II. Consumer spending slowed in all 15 categories tracked by the Bureau of Economic Analysis. The sectors that had powered the recovery in the third quarter–restaurants and hotels, for instance–reversed. The growth in spending on cars and health car also slowed from the acceleration in the third quarter. So why is this good news as far as the stock market is concerned?
