Europe shares get boost from earnings season

LONDON, April 21 (Reuters) - A raft of positive corporate earnings updates pushed European stock markets higher on Tuesday, shrugging off broader market worries about Greece's stalemate with international creditors.

The pan-European FTSEurofirst 300 index was up 0.9 percent in early trading, nearing multi-year peaks after positive updates from firms including ARM Holdings (LSE: ARM.L - news) , Actelion (Xetra: 936767 - news) and SAP (Swiss: SAP.SW - news) .

European companies are heading for their best earnings season in four years, sharply outperforming their U.S. counterparts on the back of a weak euro and improving economic conditions.

The German ZEW economic sentiment indicator, keenly watched by investors, is also due later on Tuesday.

"The (ZEW) fell short last month and given the lacklustre performance of the DAX last week the potential for disappointment cannot be ruled out," said CMC Markets analyst Michael Hewson. "A slight improvement is expected ... but this indicator is very fickle." (Reporting by Lionel Laurent; Editing by Andrew Heavens)
