NEW YORK, New York - Monday's trading session saw mixed performances across U.S. and global markets, with several major indices posting losses amid cautious investor sentiment. Piercing the record-breaking run on Wall Street, U.S. stocks tanked on Monday following President Donald Trump's decision to impose tariffs of up to 40 percent on some countries.  Allies Japan and South Korea have each been hit with 25 percent levies.

"I am pleased to announce that the UNITED STATES TARIFF Letters, and/or Deals, with various Countries from around the World, will be delivered starting 12:00 P.M. (Eastern), Monday, July 7th. Thank you for your attention to this matter! DONALD J. TRUMP, President of The United States of America," the president posted on his social media platform Truth Soical on Tuesday.
