MILAN, April 7 (Reuters) - European equities edged lower by midday on Thursday, as gains in healthcare shares were eclipsed by some weaker stocks such as Daimler that traded without the attraction of their latest dividend payouts.
German carmaker Daimler fell more than 4 percent as its shares went ex-dividend. Among other companies losing the right to the next payout were Skanska, which fell 7 percent, making the stock the biggest faller on the FTSEurofirst, and Pearson, which slipped 5 percent.
The pan-European FTSEurofirst 300 was down 0.27 percent by 1100 GMT, with investors reluctant to place strong bets. It was on track for its fourth straight week of losses.
"What markets really would need are more positive global economic data ... indicating a pick-up in economic activity, especially in the Eurozone and the U.S.," City of London Markets trader Markus Huber said.
European Central Bank President Mario Draghi said in the central bank's annual report on Thursday that the future of the global economy remained uncertain and there were questions about Europe's ability to weather new shocks.
Healthcare stocks were the top gainers for a second session, with the sector index rising 0.9 percent after the termination of the Pfizer-Allergan merger deal fueled talk of other consolidation activity in the sector.
Shire rose 1 percent after saying it expected its deal to buy American drugmaker Baxalta to proceed as expected, while elsewhere in the sector Roche also gained 1 percent and Astrazeneca advanced 1.4 percent.
Shares in STMicroelectronics gained 5.5 percent, the top gainer in the STOXX Europe 600 index, with some brokers linking the surge to the strong earnings update from its client Samsung, with the South Korean group flagging a 10 percent jump in quarterly profit.
The European technology index, up 0.3 percent, was the second-biggest sectoral gainer, with chipmakers ARM Holdings and ASML Holding gaining 1.9 percent and 1.4 percent respectively.
Wirecard rose 1 percent after the German payments processor reported a rise in full-year profit and proposed lifting its dividend.
