Shares in French nuclear giant Areva and British postal operator Royal Mail sank Wednesday in an otherwise calm day for European stocks, as the euro edged up against the dollar.
Areva tumbled in Paris after the company suspended its outlook for the next two years. Royal Mail was the biggest faller on London's benchmark index after posting a drop in earnings as its parcels division faces fierce competition from US online giant Amazon.
Later on Wednesday, all eyes will be on the US central bank, which publishes minutes of its last meeting that saw the Federal Open Market Committee (FOMC) stick to its ultra-low interest rate policy.
London's benchmark FTSE 100 index rose 0.56 percent to stand at 6,709.13 points nearing midday in the British capital.
Frankfurt's DAX 30 gained 0.34 percent to 9,488.41 points and in Paris the CAC 40 added 0.12 percent to 4,267.45.
Areva shares plunged 15.53 percent to trade at 10.19 euros in midday deals.
Royal Mail shed 7.97 percent to 431.8 pence "after it warned that growth in parcels would slow thanks to Amazon and its competitive delivery network", noted Brenda Kelly, chief market strategist at IG traders.
"We can expect more of the same from Royal Mail, while the expectation of hitting targets for the full year hinges on a good Christmas and thus the risk of disappointment is high," she added.
The European single currency increased to $1.2541 from $1.2537 late in New York on Tuesday.

"There is only a limited amount of economic data scheduled for release today with the FOMC minutes later tonight likely to take centre-stage... In the short-term markets are somewhat overbought which makes for the occasional round of profit-taking likely."
