LONDON, May 17 (Reuters) - European stocks were expected to edge lower on Friday, mirroring losses on Wall Street, following comments from some U.S. central bank officials saying the Federal Reserve could begin easing up its monetary stimulus this summer. John Williams, president of the Federal Reserve Bank of San Francisco, said on Thursday the Fed could end bond purchases later this year, Dallas Fed President Richard Fisher said the Fed should withdraw its targeted support of the housing sector now, while Philadelphia Fed president Charles Plosser said the central bank should dial back its asset buying. However, analysts said that losses in share prices could be limited as some recent poor U.S. data might prompt the Fed to keep its stimulus measures in place for a longer period than indicated by U.S. central bank officials. The Philadelphia Federal Reserve's figures on Thursday showed factory activity in the mid-Atlantic region contracted and the Commerce Department reported a 16.5 percent drop in U.S. housing starts in April. New claims for jobless benefits also unexpectedly jumped last week. "The stock market is driven by liquidity and sooner or later this must end, but the Fed is not going to take any chances. They are going to clearly signal the timing of retreat for the asset purchases, so the market won't be shocked," Koen De Leus, senior economist at KBC, in Brussels, said. "In the near term a correction would be healthy, but on the whole the market is well supported by the huge amount of liquidity that is pumped into the system by the central banks. There is not much that can derail this rally. Enjoy the ride, but protect the downside." At 0635 GMT, futures for Euro STOXX 50, Germany's DAX and France's CAC were 0.1 to 0.4 percent lower. The FTSEurofirst 300 index of top European shares ended flat at 1,245.45 points on Thursday after setting a new five-year high at 1,247.57. However, the index, which is up nearly 10 percent so far this year, is headed for its fourth straight weeks of gains. Investors will focus on more data later in the day for hints about the market's near term direction.
