Stock market plunges due to concerns about the coronavirus and drop in oil prices.

The Dow Jones Industrial Average drops for the third time in four days, losing more than 23% of its record value of 29,551 on February 12, 2020. The losses mark the end of the 11-year bull market and transition to a bear market. The Dow gains 11.4%, its biggest one-day gain since 1933, on expectations that the federal government will inject some $2 trillion into the economy, on March 24, 2020. The S&P 500 recovers to the point that it is down only 5.7% from the record high in February by June 5, 2020.
