Overseas financial markets and U.S. futures rebound somewhat after wild day on Wall Street

Overseas shares and U.S. futures advanced Tuesday, led by gains in Tokyo where the Nikkei 225 shot up just over 6% as markets calmed somewhat after the shocks from President Trump 's tariff hikes.

The modest rebound for most markets followed a wild day on Wall Street, where stocks careened after Trump threatened to crank his double-digit tariffs higher.

Early Tuesday, China's Commerce Ministry said it would "fight to the end" and take unspecified countermeasures against the United States after Mr. Trump threatened another 50% tariff on Chinese imports.
