The Dow Jones Industrial Average plunged nearly 800 points Tuesday as investors remained skittish over uncertainties around U.S. trade policy with China, fueled by a morning tweet by President Trump. The meltdown battered most tech stocks but turned out to be a mixed bag for cable shares.

The Dow closed at 25,027.07 on Tuesday, down 799 points as enthusiasm waned concerning the 90-day tariff truce in the U.S.-China trade wars struck over the weekend, after President Trump tweeted “I am a Tariff Man.”

Investors feared that animosity between the world’s two biggest economies could heighten, erasing any gains in the U.S. and rocking already shaky markets in Europe and Asia.
