US stocks on Wall Street have opened higher today after a tech sell of caused a bad start to the second quarter yesterday.

At the open the Dow Jones Industrial Average rose 0.4%, the S&P 500 gained 0.5% and the Nasdaq climbed 0.75%. Today’s bounce back comes as Wall Street fell into correction territory yesterday, with the three main stock indices now in the red for the year so far.

Investor anxiety rocked global markets yesterday, stoked by fears of a US-China trade war.

Beijing announced retaliatory trade measures on Sunday in response to Washington’s plans to unveil a fleet of new trade tariffs on Chinese high-tech imports this week.

China announced up to 255 duties on 128 American good including pork, apples and steel pipe, escalating a looming trade war between the two countries.

Beijing’s new set of customs duties followed Trump’s decision to slap taxes on imports of steel and aluminium in February, followed by US plans unveiled for 25% tariffs on some Chinese goods in March.

US tariffs up to $60 billion on tech imports related to intellectual property theft from US companies are expected to be laid out this week.
