(Sharecast News) - European shares jumped at the open on Tuesday as investors digested a raft of corporate earnings and trading statements.

The pan-regional Stoxx 600 index was up 0.27% to 611.12% at 0814 GMT. Germany's DAX was 0.32% higher, the UK's FTSE 100 gained 0.35% and France's CAC 40 rose 0.13%.

Eyes were also on the latest overnight social media pronouncements from US President Donald Trump as South Korea became his latest target for a tariff tirade.

The Asian nation, a key trade and military partner in the region, was threatened with a rise in tariffs on autos, pharmaceuticals and lumber to 25% from 15% because its parliament was yet to ratify a trade deal with America.

"The latest level of uncertainty provided a fresh springboard for precious metals, with gold advancing once more to briefly touch $5100 an ounce and with silver also in demand as investors sought to hedge their portfolio risk," said Interactive Investor head of markets Richard Hunter.

"Despite the brittle backdrop, the main US indices posted advances on the day after a losing week, as attention turned towards a raft of upcoming earnings. Four of the 'Magnificent Seven' will be reporting over the coming days in the form of Tesla, Microsoft, Meta Platforms and Apple, with most of those stocks seeing some buying interest ahead of the numbers."

In equity news, Shares in German sportswear giant Puma surged in early trade on Tuesday after China's Anta Sports Products revealed it was taking a 29.06% stake in the company.

Anta is paying the Pinault family - which owns the Kering luxury conglomerate, home to Gucci - €1.5bn to become Puma's biggest shareholder.
