European Shares Seen Trimming Latest Gains

European stocks were seen retreating on Thursday, trimming some of the previous session's gains as a drop in oil prices puts pressure on heavyweight energy stocks, but the fall could be limited as lower oil eases worries over energy costs for other sectors.

Relief could also come from the U.S. Federal Reserve's policy statement. The Fed held its key interest rate steady and reduced expectations for a rate hike at its next meeting.

Financial bookmakers, or spread betters, in London expected Britain's FTSE 100 index to open between 23 and 28 points lower, the German DAX 28 to 29 points lower and the French CAC 40 26 to 29 points lower.

Oil held above $134 a barrel on Thursday, steadying after a drop of more than $2 the previous session after U.S. inventory data showed a surprise increase in domestic crude stocks last week.
