Private employers shed 20.236 million jobs in April as the economy shut down to control the spread of the coronavirus, payroll company ADP reported Wednesday.

It's the biggest drop in the history of the company's survey, but investors shrugged off ADP's unemployment numbers and stocks rose in early trading as investors continued to bet the economy will rebound as businesses reopen.

"Job losses of this scale are unprecedented," Ahu Yildirmaz, co-director of the ADP Research Institute, which collaborates with Moody's Analytics to compile the report, said in a statement. "The total number of job losses for the month of April alone was more than double the total jobs lost during the Great Recession."

The recession of 2008-2009 was triggered by the collapse of the subprime mortgage market.

In the current downturn, about 30 million people have filed unemployment claims in the last six weeks, the US Labor Department reported.

ADP said job losses were most severe in the hospitality sector and totaled 8.6 million. Restaurants and bars were ordered to close during the coronavirus pandemic, also called COVID-19.

Other hard-hit sectors included trade, transportation and utilities (3.44 million job losses), construction (2.48 million), manufacturing (1.67 million), professional and business services (1.17 million), information services (309,000) and financial services (216,000), the ADP survey found.

The US Labor Department's report, issued the first Friday of the month, is compiled using a survey of company payrolls conducted by the Bureau of Labor Statistics. ADP's report relies on its clients' payroll data to calculate employment trends in the private sector. It therefore has a narrower base.

The reports often provides different numbers. The Labor Department's figures are considered the official jobs report.
