US stocks dived on Tuesday after a second day of stunning reversals, as Wall Street veered from jubilation in the morning towards fear at the close over President Donald Trump’s trade war, which is scheduled to kick into a higher gear after midnight in Washington, DC.

After roaring to an early gain of 4.1%, which had it on track for its best day in years, the S&P 500 quickly lost all of it within a few hours.
