European Factors to Watch-Shares seen tracking Asia higher
LONDON, April 22 (Reuters) - European shares were seen opening slightly higher on Wednesday, a day dominated by results from top firms including Tesco and Roche, following stimulus-fuelled equity gains in Asia and a drop in oil prices after Saudi Arabia ended its military campaign in Yemen.
At 0631 GMT, EuroSTOXX futures were up 0.3 percent, DAX futures were up 0.3 percent and CAC 40 futures were up 0.3 percent. FTSE futures were flat.
Top companies reporting results or sales updates included Tesco and Switzerland's Roche and Richemont. Tesco reported its worst-ever loss, Roche reported a 3 percent rise in quarterly sales and Richemont said full-year profit would drop by more than one-third after losses on financial instruments including derivatives.
The dominance of high-speed trading strategies on financial markets was also back in the news, with the U.S. Justice Department's announcement of the arrest of a high-frequency trader in the United Kingdom over charges he manipulated the futures market and played a role in sparking the May 2010 "flash crash".
And at a time when Greece's ongoing stalemate with international creditors is rippling through credit markets and Athens shares, European Central Bank Executive Board Member Benoit Coeure told Greek newspaper Kathimerini that the ECB would continue to provide liquidity to Greece's banks as long as they remain solvent and have sufficient collateral.
