Frankfurt stocks added 0.5 percent overall, and Paris won 0.7 percent as exchanges headed into the weekend.

In New York, the Dow Jones index was up by 0.6 percent in midday trading.
Oil prices took a stab at recovering from this week's sharp selloff meanwhile, while the euro declined against the dollar.
Investor sentiment brightened after survey data showed eurozone business activity growing at its fastest rate in three years, as Europe's economy emerges from months of Covid-19 restrictions.

The group also revealed that Britain's activity enjoyed record growth in May, jumping to 62.0 thanks to strength in manufacturing and services.

Sentiment in the region continues to be torn between inflation fears and optimism over the economic recovery.
Asia's week finished on a mixed note despite data showing the number of people applying for US unemployment benefits fell for a third straight week to a new pandemic-era low, reinforcing expectations the recovery was well on track, helped by huge government and central bank support.
