S&P 500 suffers 2-day drop not seen since 2008

One day after President Trump tweeted that the stock market is "starting to look very good to me," the markets once again took a dive.

The Dow Jones Industrial Average fell 879 points on Tuesday after the Centers for Disease Control came out with a dire warning about the coronavirus, saying its community spread in the United States appeared inevitable and Americans should be ready for the potential of major disruptions in their lives, CNBC reports.

Additionally, the S&P 500 on Tuesday fell about 3 percent, and CNBC notes that "the last time the S&P 500 fell more than 3 percent two days in a row was in November of 2008 during the financial crisis," citing Bespoke Investment Group.

Dr. Nancy Messonnier of the CDC's National Center for Immunization and Respiratory Diseases said Tuesday that the coronavirus spreading in the U.S. is "not so much of a question of if" but rather "a question of when," and "we are asking the American public to prepare for the expectation that this might be bad," The New York Times reports.

This came after the Dow on Tuesday plunged 1,031 points in what NBC notes was its worst performance in two years.
