The New York Stock Exchange's massive post-COVID question Read full article Oops! NEW YORK, NEW YORK - MARCH 20: Traders, some in medical masks, work on the floor of the New York Stock Exchange (NYSE) on March 20, 2020 in New York City. Trading on the floor will temporarily become fully electronic starting on Monday to protect employees from spreading the coronavirus. The Dow fell over 500 points on Friday as investors continue to show concerns over COVID-19.

It was the first time in 228 years that the floor was closed but markets remained open. (The floor and trading were both shuttered for two days after Hurricane Sandy in October 2012 and four days after 9/11, more on the latter, later.)
