Stock futures fell early Monday as the market reacted to more tariff threats from President Donald Trump–this time targeting the European Union and Mexico. Trump said that 30% levies on imports on two of the U.S.’s largest trading partners would go into effect on August 1, in letters released Saturday. Futures on the Dow Jones Industrial Average fell 133 points, or 0.3% in premarket trading, while S&P 500 futures and Nasdaq 100 futures were also down 0.3%.
