Despite the market being up early on Tuesday, reacting to reports of ongoing trade negotiations by the Trump Administration; the U.S. Stock Market today closed down for the fourth day in a row with the Dow dropping roughly 320 points, while the S&P 500 and the Nasdaq Composite fell 1.6% and 2.2% respectively, removing any gains made earlier in the day and wiping out nearly $1.5 Trillion.
