U.S. stocks surged as President Trump addressed the nation Friday. Each of the three major exchanges saw gains over 9%. 

The U.S. president announced partnerships between many private sector companies in the battle against the spread of COVID-19. 

Walmart, Target, Google, and others will be working on a COVID-19 drive-through system to help Americans get tested. 

It wasn't clear who would pay for the system or how much the drive-through test would cost.

The U.S. president also said the government is waiving interest on federally-owned student loans until further notice and that the U.S. will also buy "large quantities" of oil for reserves.

The stock market had its worst day in nearly 30 years this week, as coronavirus fears swept the markets. 

Trump announced sweeping travel bans on Europe and had to walk back comments made during an address to the nation Wednesday when he incorrectly said all goods coming from the EU would be banned.
